11 Creative Marshmallow and Toothpick STEM Challenges

STEM Challenges can be low cost ways to incorporate learning concepts in your classroom or maker space. One classic favorite of mine are marshmallow and toothpick challenges. We started a Creator Club a few weeks ago. Our kids meet once a week to do hands-on learning projects. We have kids from 4K to 4th grade. As you know that range is wide in abilities. The great news is that there are plenty of activities to do with wide ranges of children. Our first week we dove right in and taught the students how to use hot glue guns so they could build craft stick truss bridges.  This past week we had so much fun creating with marshmallows and toothpicks. I created a list of challenges that I dug up from the internet to use. After a successful Club, I thought you might benefit from this list of ideas, too!

A few tips before you try this activity: let your marshmallows get stale. I opened my bags two days early and that was enough to help them get a little crusty and help them stand up better. Because we’re closing in on Valentine’s Day, we had a little fun with some heart marshmallows I found! Using themed marshmallows adds an additional element of interest. We had no problems keeping the interest for an hour with these challenges. Finally, keep some of your marshmallows fresh. In an effort to curb uncontrolled eating of marshmallows, I told the kids that I had fresh, soft, non-crusty marshmallows for them…I don’t think a single kid ate a crusty marshmallow. They did ask me repeatedly for the “good” marshmallows – but I’ll take that over sugared up kids! I handed out marshmallows about 2/3rds of the way through the club time, when I noticed they were getting a little restless. The quick treat break had them back to building in no time and they were engaged and focused even after eating!

We did not get through ALL of these challenges in one night…but I’m happy to have these ideas all in one place for the next time around. Hope it helps you save some time, too!

  1. Build one dimensional shapes. For younger students this is a great way to reinforce basic geometry. Shapes that worked well for us included: triangle, square, rhombus, rectangle, trapezoid, parallelogram, pentagon, hexagon.

  2. Build three dimensional shapes. The kids went crazy over these. Building pyramids, cubes, prisms, tetrahedrons, and rectangles (I believe the geometry term is hyperrectangle). These small structures were great opportunities for the kids to explore support. Some recognized immediately that their shape wouldn’t stand up with out connecting enough marshmallows and toothpicks. It took others a little longer. We found fun in the falling – but reward in determining how to get it to stand on its own.

  3. Create letters. I see so many opportunities for this from practicing the alphabet to spelling names, to snap words. It may also help reinforce letter structure for those students that sometimes struggle with forming letters. Idea from: Fantasticfunandlearning.com

  4. Build a house. The kids built simple houses at the beginning, but it didn’t take them long to begin experimenting with adding on and growing their houses (and tree houses!).

  5. Build a tall tower. Using our shapes in #2, we discussed the importance of stability in a structure. They built towers using different three dimensional shapes. We discussed the strength found in a triangle. A prism shape worked well for creating taller towers.

  6. Build a bridge. Once you tackle towers, bridges are a natural transition. This is a good small team exercise.
    Idea from: Meredith Vance

  7. Build a pyramid. Just like the bridges, this is a project best suited for small teams. Students can be challenged with limited marshmallows and toothpicks, or limited by time. This helps them stay focused and on task.

  8. Create animals. We loved this challenge! The kids created birds, lions, pigs, long dogs and other unique animals.
    Idea from: ApartmentTherapy.com

  9. Design a snowflake. We’re still in the thick of winter, so a snowflake challenge fits the mood around here! I thought the kids would be more excited about this one, but I think if I had older ones they would have gone crazy.
    Idea from: Julie Bennett

  10. Create a sculpture. I often try to build in time to free build. Sometimes I set a theme such as plants, animals, fruit, vehicles, buildings, holiday themed (Valentine’s Day!). Other times I just let them build.

  11. Make a constellation. I loved this idea when I spotted it on pinterest. Students love talking about space. Combining a natural interest with a STEM project can be great fun.

5+ Ways To Crush Boredom In Your Classroom

Are you tired of your students whining about being bored? Children have beautiful, naturally curious minds. But when those creative minds aren’t challenged, it quickly turns to whining and complaints. Captivating your students can be fun. Learning can be exciting and engaging! We have a few tips to help you stretch your wings and help turn those classroom protests into cheers. Or at least not whining, which is okay, too! Over forty years in classrooms from fourth to eighth grade taught me a lot about engaging students in learning. Worksheets almost never worked. What did work? Authentic, hands-on, creative lessons that made learning come to life. Here are some ways to get started!

  1. Have some fun! It’s okay to enjoy your time in the classroom. Not every moment must be spent serious and focused on the task at hand. If you have a high whining incidence happening in your classroom: Check yourself first. Are you feeling stressed about something? Are you trying to pack everything in. Set aside a few minutes to be silly with your students. It doesn’t have to get out of hand! Kids go crazy for Would You Rather…We’ve also had great fun with numbers while waiting (in line for specials, lunch, recess, the bus)! We like games that you can do on the fly – maybe it’s choosing one child to give you two numbers to add or multiply. Maybe it’s counting by 2s, 3s, 4s, 5s, 15s! Have them chime in and see who can get the furthest with their skip counting. {A pinterest board with some game ideas!} Or have some fun with words like Meridith @fromtheteachersdesk — she made a play on words for her students to help them remember! Play works for all children. It cuts right through boredom EVERY. SINGLE. TIME.
  2. Get Out of a Rut. We’ve all been there. Grateful that you’re teaching that grade for the second, third, tenth year…it’s less prep for you, and you have tested and tried what works (and eliminated what doesn’t!).It might sound terrifying…but consider stepping aside from your trusty plan. Studying oceans? Turn your classroom into an underwater exploration complete with a “submarine” your student scientists climb aboard to do research! Cover some of your lights with rolls of blue clear plastic. Create a wall-scape or bulletin board that shows the areas of the ocean that receive different amounts of light, maybe even include a display of our tallest land features (buildings, mountains) to show just how deep the ocean is! Populate your wall-scape with sea creatures common and unique…Have a Sea Harvest Day where students bring in a recipe made from ocean delicacies (also a fantastic way to incorporate cultures and how many populations depend on sea life for their primary food source).  Yes, it will be more work, but even middle schoolers benefit from the interactive, hands-on learning approach.
  3. Make it Authentic. Create fun activities that reinforce boring concepts through the use of games: a stock market game, a hamburger shack where students hone their math skills, escape games for the classroom that encourage teamwork and critical thinking, games to reinforce probability, fractions and decimals (ours involve shooting wadded up paper at garbage cans and counting – and eating – candy) (these are all at our TPT store). Simple acts of incorporating a little more meaning into what could otherwise be dull, repetitive work turns your classroom from boring to exciting in no time!
  4. Give Up Control. Yikes. Did I really just say that?! Yes. I did. And I know it is not always a popular concept. A controlled classroom (and children) is a productive classroom. Ohh, but it is painful for children to be trapped. Give them options for alternative seating! Wobble chairs, bean bags, poofs, fuzzy bath rugs, mini bicycles, exercise balls, standing desks, anything to let them choose a little freedom. These don’t have to be an all-the-time option (in fact, sometimes limiting it to certain work times can make the seating even more effective!).This is true for your lessons, too. We found so many ways to incorporate lessons into our Makers Space. That’s a whole new level of letting go of control, but the rewards are students who will amaze you with how they grow. Yes, they can learn how to use hot glue, screw drivers, drills, hand saws, sharp scissors, sewing machines and more!
  5. Make it a Challenge. Kids LOVE challenges. Even the most non-competitive students will find something to enjoy if you give them a challenge. We’ve studied physics by doing a roller coaster challenge. Teams are given a supply list and a budget. They can then choose their supplies but must stay in the budget (including track – or pool noodles!, a roller coaster card – a marble, tape, etc.). From there they build their roller coaster but must keep their cart safely on the track! Students learn speed and velocity, gravity and more through trial and error of building their track.We’ve also built a Sail Car with similar concept as the Roller Coaster Challenge. Teams get a given set of supplies and they must use the Engineering Design Principle to make their car travel the farthest or to a finish line. Students can easily be frustrated when their first attempts don’t work, but they develop persistence through trial and error, and bettering their prototype until the final race day!In our Makers Space, we built cardboard and duct tape boats and ACTUALLY LAUNCHED THEM on a lake. The only limit to these challenges is your imagination, and even then, we’d be happy to help you if you feel like you don’t have any ideas. So…there are no limits here!
  6. Get Out of the Classroom. All of your learning could be done in your classroom, but it doesn’t have to be. Tight budgets and testing pressures often make us feel like we need to be strapped to our desks, shoving knowledge into our students at every possible moment.The beauty of children is that learning will occur in any environment. They naturally and readily soak up information while engaged. Find ways to get out of your classroom. That might look like doing messy science on the playground blacktop. Maybe it’s walking to a local nature preserve, library, town museums, fire department. It might even be full day field trips to historical landmarks, science or history exhibits, natural sites, local businesses, the post office, your state capitol building…and more. {Another pinterest board here!}Fourth grade was my favorite age to teach for a variety of reasons, but one big part was the opportunity for field trips. I grouped our trips by location so we state capitol building and a cave on the same day. On another day we explored an Ice Age Center where we learned how glaciers formed our natural topography, we also visited an effigy mound park made by Native Americans who once populated state. On another trip we visited a dairy museum (because we’re known as the Dairy State) and Aztalan park, another historical landmark that pointed to our state’s history.I planned multiple day camps for 7th and 8th graders where we did team challenges, ropes courses, learned to cook meals and clean up each night, we told stories and sang songs, we studied nature and explored. Where you live has a particular value that you can incorporate into your classroom. Seek it out and get out of the classroom.As a last resort, use technology to bring your field trips inside. Although I really believe in getting your students out of the classroom, there are just some things you probably can’t do because of location, cost, or maybe even bureaucracy of your school system. Make a way.When you put student learning first, there’s always a way to make it work!
  7. Clear the Clutter. I’m notorious for being a slob. My classroom always smelled like feet. Okay, maybe that wasn’t on me! My natural tendency leans towards chaos (#4 above {Give up control} isn’t too hard for me!). It drives my wife insane. Despite this natural tendency for mess, I have seen first hand how clearing some clutter helps students relax, focus, and whine less.At the end of the day today, take some time to look around your room. You spend hours decorating and, especially in the younger grade levels, you need a lot of support items. Is there a way you can reduce the noise a bit? Can you tuck some tools into a cabinet, or cover with a blank space. Do you need all of your posters hanging up or could you rotate them throughout the year? As difficult as this is for many of us, because we LOVE ALL THE COLOR!!!! — I challenge you to tackle this with fresh eyes. Take a few steps towards streamlining your classroom today. Your students will breathe easier and be ready to work harder.

Do you like this topic? Do you want to learn more? Give us some feedback! We’d love to help empower you to stretch and grow in your classroom so you can love going to school every day…and your students will be happy to be there too! Follow us on Instagram, Facebook, or Pinterest for new ideas.

How to Create a Fire Safety Unit that SIZZLES!

Fire Prevention Week falls annually on the second week of October. This year that means it starts on Saturday, October 8 and runs through Saturday, October 14. It’s a great time to help your preschool, Kindergarten, First and Second grade students learn how to be safe in a fire and prevent fires in the first place! Fire Prevention Week holds a special place here at Brain Brigade, where Jerry was a volunteer firefighter for over 30 years. Tie his teaching and firefighting (and education) experience together, and we have created some awesome ways to carry out Fire Safety and Prevention into your classroom.

  1. Know your Facts! Help your students learn their address and how to dial 9-1-1. Younger students in the pre-K level respond well to using a pretend phone to dial 9-1-1. Simulate a conversation by answering another phone and asking questions like: What is your name? What is the problem? Are you hurt? Is someone you know hurt? What is your address? These tools can help a child be a hero by learning to speak clearly and feel confident with the types of questions they might face.Older students will benefit from learning their address and phone numbers. Have them practice writing it out. Or send it home as an activity to do with an adult.
  2. Tour a Fire Station. Most local fire departments love having visitors. They often have an educational program in place to host students. Get out of the classroom for a great field trip. One local fire departments hosts their kindergarten class each year. They have stations where they show the protective gear that a firefighter wears (dual purpose to explain why a firefighter wears gear, but also to help children to not be scared if they would be in a real fire). They have a station where the kids learn about fire equipment and tools on the fire trucks and the ambulance. They get to climb through and ambulance to see what they might experience if they are in an emergency.
    The students also watch a fire safety video and get fun give aways including their own fire helmets, coloring books, and more. Then they head outside for activities. They get to try spraying the hose at a “house fire” which is basically a wooden house with a wooden fire in the window. The “fire” is on a hinge, when the spray of water hits the “fire” it tips backwards on the hinge! And finally, they take groups of students on a fire truck ride around the block. The kids love it, but they also leave with confidence in what might happen in a fire or emergency, and how to keep themselves safe.
  3. Invite a Firefighter to Read. To complement your field trip, or if you are limited in your field trip options, invite a firefighter or chief to come read to your students! You can bring a partial fire station experience right into your classroom. Have the firefighter(s) read to the class as a whole, or break into smaller groups. Ask the firefighters to bring in gear and tools for students to touch and feel.  Have students prepare questions in advance (we all know the question that begins, “There was this one time…”!!!).
    One of our favorite books is The Fire Cat by Esther Averill. In this book, Pickles the Cat knows he is destined for big things, but he’s not quite sure what. He gets into some trouble and is not friendly to the other neighborhood cats. One day, he gets stuck in a tree and firefighters rescue him. He gets approval from the Chief to stay at the fire house…if he can be a good cat. Find out what happens to Pickles as he tries to earn a spot at the fire station!
  4. Develop vocabulary with a Fire Word Wall. Fire words make fantastic vocabulary words. Students are eager to write stories and draw pictures with words that are filled with danger and excitement! We have a list of almost 40 vocabulary words, some more challenging, in our Engine 65: Get to the Fire classroom resource. When you build a word wall and encourage your students to write a fire story, you’ll be amazed at how creative they can get!
  5. Make fire safety learning into a classroom game. We might be biased, but this is our favorite way to help students learn. Kids love games and we try to make games out of many of our subjects for our older students. Fire Safety games and activities are a perfect way to engage your students without whining!

    Not sure how to create a game? Read this post on creating classroom games. You can also read, Explore Like a Pirate by Michael Matera, to get insight and inspiration in creating games in your classroom.
  6. Play pretend! Kids love playing pretend and it is a great learning strategy. Have students create their own fire helmets to become firefighters. Then create stories to practice skills. Have students call 9-1-1 and recite their address, practice getting low and staying low (crawling on the ground because of smoke), practicing touching doors with the back of their hands to see if it is hot, etc. Pretend is a fun way to reinforce what students have learned! Make a helmet, have students decorate and cut out. Use bands of paper stapled to the helmet to customize the fit to each child’s head.

    And if you’re short on time, grab our Engine 65: Get to the Fire game. It’s a fast, easy download and you’ll be ready to print in no time.


Secrets for Creating Escape Room Units for Your Classroom

Family time

Dinner together after the Escape Room!

On a family getaway weekend near Blueridge, Georgia (have you been? It’s such a great family vacation spot!). We stayed at a mountain retreat with stunning views (check it out here – not an affiliate link – we just loved it!). On our trip, we went to an Escape Room and there was no going back! Have you been to one? They’re more fun than I expected. And, being the teacher that I am, I couldn’t wait to put together a version for the classroom. It’s a fantastic way to work cross-curricular concepts into a single lesson. I have some tips and tricks to share for creating your own Escape Classroom activity. These activities will challenge your students to think creatively and critically while working together as a team. It gets your students moving around the classroom and into problem solving mode!

Moonshine Mountain Lodge, Blueridge, GA

Sweeping views at Moonshine Mountain Lodge!

Moonshine Mountain Lodge, Blueridge, GA

Seriously one of my favorite vacation spots.








We began with a study of Ancient Egypt. Students explored (as a team) various math, history, science and language arts concepts while solving team challenges. I suspected that my students would enjoy it – but I wasn’t prepared for how they begged for more!

So I’m launching a new one exploring the United State’s Race to the Moon, and have another in the works exploring volcanoes! The kids are going to lose their minds. Ha!

The Race to the Moon is a bit longer and more involved and will take about two weeks for my kids to complete. I’ve dug up YouTube videos to accompany each riddle which has completely re-inspired me in what a country can do when we’re all championing the same cause.

We may not be able to all get behind climate change, healthcare or education systems, or how even our country is run – but I’m pretty sure you’re here because you can get behind being creative in your classroom and engaging your students in a fun and unique way. Let’s get behind that together.

So here are some of my secrets for creating these units:

  1. Choosing a Topic – What’s your specialty? Language arts? Choose a book you’re studying! Science? Incorporate labs into your challenges.
  2. Perspective – Our Ancient Egypt study was broad enough to be multi-disciplinary but we tucked facts into each riddle. Our Race to Moon unit walked students through the timelines of each launch, and the progress (and failures) necessary for the US to set foot on the moon. Our volcano lesson is in progress, but this one is more of a story line of a fictional character who lives in Herculaneum in Ancient Rome who is nervous that the mountain, Vesuvius, is going to erupt and destroy his family and their home.
  3. Challenges – This is where it gets fun! My original ideas spurred from a few of the escape room ideas, but I’ve since branched out. From finding differences in pictures, to solving secret codes, to solving math problems.
  4. Creating the Incentive – This one is a piece of cake. Break up your students into small team and let them after the game. Competition will entice your students to keep after each answer even when the riddles get tough! The Race to the Moon is a bit more involved and we added a currency portion that adds an extra element of fun (and an assessment activity similar to Jeopardy where they can leverage their currency to win!).
  5. Assessment – Speaking of assessments…these are some of the easiest assessments in my experience because the kids don’t have the aversion to traditional assessments. We build a pyramid in the Ancient Egypt program…they have no idea they’re being tested!
  6. Have fun – Seriously. Your students are going to have fun if you get into experience with them. Build a pyramid! Launch a rocket! Explore lava! Don’t forget to be allow yourself to be in awe and let that spark fuel your lessons.

Still not sure where to start? Give ours a try and then come back and tell us what you create!

How to Design an Awesome Maker Space to Bust Summer Boredom

Summer is just around the corner and it is time for me to get our Maker Space at home back into full gear before school lets out! We moved last fall and we haven’t found a great place to set up our Maker Space.  Although our house is significantly larger (we were in an 850 square foot house – so everything is bigger here!), I’m still gauging how we use this new space. I find that my son is generally within 20 feet from me (probably because that’s as far as we could get from each other during the first five years of his life because of the 850 square feet we occupied!).  So here we’ve been for six months using any space around this place as our Maker Space. The kitchen table. The coffee table. The LEGO table. The basement. The floor! We have a great space upstairs that is almost like a small loft, but I’m afraid it won’t be used as often as if we keep it on our main level (ahem, that 20-feet-from-me-at-all-times-issue). Plus, we have the great fun of having my 13 year old niece and almost-9-year-old nephew hang out during the summer and having them upstairs removes me from the fun! It’s a real dilemma. What’s not a dilemma: Learning. Learning doesn’t have to halt simply because summer vacation is here. Learning should be fun, exciting, and spark curiosity especially during the summer!

We originally established a Maker Space in our home to encourage this mindset. What exactly is a Maker Space? Definitions vary, but we define it as, “A place to encourage and inspire children to challenge themselves, to explore, to learn to think creatively, critically, and problem solve.” Your child may have a Maker Space at school, but it can also be set up in your home. A small table, desk or workbench will get you started. As I shared above, right now our Maker Space is fluid. During the summer we extend it to a workbench outside. What does matter is giving your child the freedom to explore ideas, to be successful and even permission to fail.

Inevitably, your child will create a project and it will fail. A perfect example of this is a boat my son wanted to design this winter. He watched a youtube video of a homemade steam powered boat and went to work building it. I took one look at it and knew it wasn’t going to work like in the video. But he was determined and it did float and sort of work before capsizing! A year ago, this same kid would have been angry and quit. But this time, he had a breakthrough. He laughed and we talked about what might have make it sink and what he could change for the next round. And he went right back to work.

No matter your age, failure is a part of life and we use our Maker Space to help our son learn to navigate that process and contribute to a growth mindset. My son is not naturally prone to a growth mindset (and to be honest, neither am I!). Giving him the opportunity to fail in a safe environment has helped him develop greater creativity and persistence.

How to get a Maker Space started in your home:

For young children, dig out your craft supplies. My son was about three years old when we really dove in. By four, he was using a hot glue gun under close supervision. Now, at age five, he uses it on his own. You know your children best – guide them, teach them, and train them to use various tools.

CAUTION: Don’t stand in their way. When Finn was really young, my dad scolded me for doing something for him that he could figure out on his own. He struggled, but he ultimately got it. It was the most difficult lesson of parenting that I have learned. In fact, I’m still learning it. Often I have to ask myself, “Is this something that he can do for himself? Or learn to do for himself with training?”…and more often than not, the answer is yes. Parents let go of the control. Seriously. It has given Finn confidence, motivation, and drive. He is a better person for it. He is more engaged and curious because I allow him to go!

Back to the craft supplies…Make materials available and accessible. Some ideas to get you started:

  • clean recyclables
  • cardboard
  • duct tape, masking tape, scotch tape
  • glue
  • scissors
  • pipe cleaners
  • straws
  • craft sticks
  • string
  • beads
  • wood
  • paint

Start with materials that you already have. Don’t feel the need to run out and buy anything until you get a good feel for what you have. You may not even need to buy anything (other than duct tape and hot glue. I’m perpetually restocking these!).

Alternative resources:
I don’t always know how to do what he is imagining, so we use the internet to search for tutorials and videos. Sometimes, I give him a challenge, other times I let him explore on his own. We generally come back to testing and improving, but sometimes we just have fun. The trick is letting go of controlling the process. Allow your child to drive the project and do the work! That’s where engagement and learning are at their best.

Growing with your Maker Space:
Older children continue to enjoy creating with the materials listed above, but can learn additional elements. You may have a child who loves to help in the kitchen. Challenge him or her to create a series of more difficult recipes. Begin with an easy recipe, maybe three or four ingredients and a few steps. Let your child do it! Am I getting point across yet?! It is very difficult to let go of control. It might get messy. It might not taste great. But one recipe at a time, your child will develop and improve. Before you know it, you might get a day off from cooking dinner (#momgoals).

Older kids can also explore more in-depth concepts. We build cardboard and duct tape boats and test them on a local lake. We love circuits and use inexpensive SMD LEDs and copper tape from SparkFun. Explore coding through a free program: Scratch, from MIT. Teach how to use tools and give your child access to wood, nails and screws. Encourage your child to plan by sketching and listing required materials before building. If your kid is into LEGOs, give stop-motion video a try. The possibilities are endless.

Maker Spaces don’t need expensive equipment. They do need adults willing to support through trials, the freedom to try something new, and a bit of grace when things get messy. Join in the fun once in awhile! Everyone can benefit from making.

Check out our guide to Designing a Maker Space – it can be used in both a classroom or home setting!

Experimenting with Hydroponic Gardening to Grow Strawberries

STEM STEAM Science Hydroponics

If you’re new to our blog, welcome! We generally talk education topics like STEM, STEAM, science, hands-on learning and maker spaces. But in our spare time, we tinker! And now that Jerry of Brain Brigade has officially retired from teaching…he has MORE spare time! We have been involved in many hydroponic and aquaponics projects in the classroom and maker space, but we have been diving in to various hydroponic methods of growing plants at home.

Last summer I visited Iowa and I noticed a really clever hydroponic tower that was growing lettuce. It was made of PVC pipe that wound around a central tower. I thought that the idea was great. It was compact and allowed for maximum use of growing space for sunlight and circulation of nutrient solution. This winter I began to wonder if something like this could be used to grow strawberries hydroponically. After a bit of research, I decided that I would try to make a tower similar to the one that I has seen.

STEM STEAM Science Hydroponics

This is a photo I took in Iowa of lettuce growing on a hydroponic tower.

As I looked at 4 inch PVC pipe I soon realized that it was very heavy and expensive. I decided to use a lighter plastic pipe that I found at Home Depot. It used the same 90 degree elbows that the heavier pipe used. I first constructed the frame that I would mount it on using 1 ½ inch PVC, elbows and a cross piece at the top to connect all of the frame. I mounted this frame on a wooden base and drilled holes to secure it with bolts. Next, I determined that the PVC pipe surrounding the frame would have to be cut at 25 inches. I bored 3 inch holes in the pipe using a circle drill and mounted the pieces to the frame using plastic straps and bolts. I also purchased a 10 gallon tub for my nutrient solution that sits inside the bottom middle of the frame.STEM STEAM Science Hydroponics

I ordered 50 strawberry plants from Jung’s called Tristar that is ideal for hanging baskets and produces a crop in summer and in fall. I also ordered strawberry nutrient from Amazon. My only concern, is that the pipe connections at the elbows will leak because I have not cemented them with PVC cement. I will use my pump from my hydroponic system in my basement to pump the nutrient solution to the plants. I won’t be using the pump during the summer, so it’s a nice way to utilize my materials all year long! Now. We just need it to get warm around these northern parts!

Maybe you’re thinking, “this is cool…” but aren’t quite ready to take on The Tower quite yet. You could give windowsill hydroponics a try to get your feet wet! It’s an excellent classroom project too.

How to Light Up Your Classroom with Bright LEDs

STEM STEAM Science Classroom Maker Space

In this step-by-step tutorial, we show you how we used SMD LEDs and copper tape to create a parallel circuit. The result is a glowing spring card to share with a friend! This project is easy. A perfect beginner activity for introducing LEDs as a STEM or science concept in your classroom. Students will be deLIGHTED {pun intended!} to see their project glow. Get the full download here that includes the printable card and copper tape diagram and information on where we purchased our inexpensive supplies!

STEM STEAM Science Classroom Maker Space

Step 1:
You will notice that the SMD LEDs come in a black strip of 25 small compartments. The tiny lights  can be removed by peeling the strip of clear plastic off of the back of the black strip. As you do this, the small lights will fall out of their containers. Make sure to catch them and place them in a container that you can label and seal so you don’t lose them. I separate by color.

STEM STEAM Science Classroom Maker Space

Step 2:
Print out the card templates on cardstock or heavy paper. Choose two-sided print so that the two pages prints to one sheet of paper. You can also design your own card by drawing or using a computer program to create your desired design.
Step 3:
Fold card in half so that the flowers (or your design) are on the outside. The card will open at the bottom and you should be able to see the inside of the card. This includes the circuit template and personal message lines.

STEM STEAM Science Classroom Maker Space
Step 4:
Open the template back up. Punch holes in the center of each of the flowers. You can use a long hole punch, a paper piercing tool, a sharp pen or pencil, or any other tool you have around.
Our paper punch wasn’t long enough to reach, so we used a tiny screwdriver. We placed our card on a stack of scrap paper to protect the table. Next, we carefully scored around the circle with the edge, pushing firmly but not through the paper. Then we gently pressed around the edge, once again following the edge of the circle and the center circle popped out leaving a
small hole.

Step 5:
Once you have created a hole in each of the flowers, fold the card back up. Mark you hole location using a marker. The marker will leave a dot on your card template that will show you where to place your LED.

Step 6:
Locate the dark gray lines on the diagram. You will be placing copper tape strips on the lines. If you are designing your own, simply look where you have marked your LED placements. We had three flowers, and used three LEDs. This is where you will need to map out how you run your copper tape.

Step 7:
Begin placing the copper tape on the negative (-) side of the diagram, peel off the backing so that the sticky side adheres to the paper.  For your personal design, begin placing the copper tape on one side of the LED dots, keeping one long piece of tape that will run to the battery. The negative side will go under the battery and make contact with the negative terminal on  the battery.
TIP: When making a turn with your copper tape, first fold the tape in the opposite direction of the way you want to go. Then fold it back into the direction and smooth when you are complete.

Step 8:
Use the side of a pen or marker to smooth the copper tape to the paper.

Step 9:
Locate the positive side of each circuit and place the copper tape. Place the battery positive (+) side up in the circle. If designing your own, you will once again locate your LED marks and run the copper tape parallel to the first copper tape you placed.
TIP: Place the positive (+) tape VERY close, but not touching the negative (-) side of tape. The strips of copper tape must be very close so that the tiny LED can connect to both sides, but if the tape touches it will short circuit!

Step 10:
When you get to the battery, stick the copper tape to the positive (+) side of the battery which should be facing up. See photo for close up details.
Step 11:
Using scotch tape, adhere your battery to the cardstock so that it doesn’t move around.

Step 12:
Time to get out your SMD LEDs! Take a closer look at your LED bulb. You’ll notice a clear side, and if you turn it over, a flat side with a green “T”. This is important for knowing which side is the positive (+) and the negative (-). Energy can only flow through an LED one way, so you must put it on the copper tape the correct way so that it lights up. The top of the “T” attaches to the positive (+) side of the copper tape. When you place your LED, look at the “T” before sticking to the tape!

Step 13:
To place, we use a small piece of scotch tape to “grab” onto the top of the LED (the clear part). Then lift the tape and LED up and look at the “T” on the bottom. Use the tape to adhere the LED onto the mark that you made in Step 5. If you have the LED on the correct way, it should light up!
Step 14:
If the bulb doesn’t light up, remove the LED, rotate it 180 degrees. You may have had the positive and negative connections placed wrong. Test again. If it still doesn’t work, review our troubleshooting guide.

Step 15:
Place the other two LEDs following the same process.

Step 16:
Build a switch! To turn off your card, simply slide a small piece of paper under the battery to disrupt the current between the negative terminal of the battery and the copper tape!
