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.

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.

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.

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!

STEM STEAM Science Classroom Maker Space

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!

How to Troubleshoot LEDs Like a Pro

LEDs STEAM STEM Maker Space Classroom Science

A huge part of our teaching philosophy is to help students develop persistence and become proficient at problem solving. But developing those skills isn’t always easy. We live it out around here so that it’s easier to teach in the classroom. We tinker in our spare time. We encourage the kids {actually, everyone} in our family to ask questions and work out solutions. We often ask for help and work together to solve a problem. We recently finished a new light up project; a greeting card that celebrates spring. We designed a cover with three flowers and put our tiny LED lights so that when the card is closed, the LEDs light up and illuminate the flowers. This particular circuit had two switches that were activated by a finger push. Since we were operating two switches from the same battery, we needed to hard wire the battery into the circuit and place different circuits for the lights. It was tricky to say the least, and since I had not tried this before, it took some time to think it through.

STEM STEAM Science Classroom Maker Space

I’m still not convinced that I have the best circuit path for this project. My plan had a small finger push button for each light. When I pushed down on a spot, a piece of copper tape that was stuck on the inside cover of the card made contact with the broken circuit of one light and completed the circuit thereby causing the light to come on. Needless to say, much tweaking was needed.

First, I had to make sure that the copper tape that completed the circuit was positioned exactly above the break in the circuit, so when I pushed down it contacted both ends of the broken circuit. Next, there seemed to be a problem with the LED lights that were in the circuit. I just could not get them to stay on. I finally determined that the copper tape was too close together and the lights were actually shorting themselves out.

Next, the circuit began to act up again and would not consistently light the bulbs. In checking and rechecking the circuit I found where the copper tape touched the battery, it was making contact with both the positive and negative portion or the battery and shorting the circuit.

At times, it can be very frustrating troubleshooting whether it is circuits or programming. What I have learned from this is that there are many ways a circuit can fail. Hopefully, in the future it will help me problem solve more quickly.

You can try this card – we have two tutorials – a beginner version with no switches and an advanced version with the two switches!

Introducing LEDs and Bright Fun to Your Students!


LEDs, or their long name, “Light Emitting Diodes” offer a great deal of cheap, impressive fun in a classroom or Maker Space. We’ve used LEDs with students as young as third grade with great success. Students can explore and create incredible projects once they understand the basics of LEDs. Using SMD LEDs offers many learning opportunities for exploring circuits, trial and error and persistence. Plus, they’re inexpensive…a bonus when you get big results without blowing your classroom budget.

When first exploring LEDs, I was intimidated. My first order from Sparkfun arrived and I couldn’t get the LEDs to work. As it turns out, I didn’t have the LEDs removed from the packaging correctly {true story!}. The first time I placed the LED onto the copper tape it lit up like magic. I was hooked. I wanted to light up everything in sight. It was like a new toy. What else could I make glow?

Completed 3D Washington Monument. It glows red like the real one {Safety first. I think so planes don’t hit it!}.

We’ve been using these powerful little lights mostly to enhance paper projects. We enjoy using them because of their low power consumption and long life span. They have great luminosity and can brighten a dark room. LEDs are great for teaching polarity because the energy can only flow one way through the light. They’re powerful and impressive. And kids love them.

Even Leprechaun’s are rumored to love LEDs!

After my own trials {ahem, having fun}, I was ready to bring them to the Maker Space. I started the students off with some holiday cards that had a template to follow. We created one where Rudolph’s nose glows and the other a Christmas Tree. Then we got crazy. We created a light-up, pop-up 3D glowing Valentine’s Day card. We built a 3D Washington Monument that lights up like the real deal! We made a simple St. Patrick’s Day card for younger students. And we keep exploring…most recently we created a Spring Card that has two switches. So.Much.Fun.

 

Experimenting with LEDs. How many can you light up at once and for how long?

The kids enjoy it as much as I do! I have had middle school students have great success. Once they grasp the basic understanding of parallel circuits, how to make switches and comprehend what a short circuit is, they incorporate them into their own projects.

We’re now experimenting to determine how long 14 LED lights will stay lit off of a coin cell battery. They were still glowing after an hour. With this new information, we hope to incorporate these LEDs into light up constellations that can be made into an interactive bulletin board where a student can press a button and see the constellation light up! We’ll keep you posted!

Transform Your Teaching by Thinking Backwards with Seth Godin

Podcasts

I have recently become a podcast addict. I use the app Podcast Addict which just feeds my hobby. Yes, I now call it a hobby. It’s feeding my mind in a way that books used to {pre-kid days}. I still read, but not with the voracity that I used to. Now, I can fill my brain with quality words and ideas all while scrubbing my dishes or working on my design work. It’s another way to boost my creativity and inspire me.

I have a few podcasts that I’ve really begun to love, but in an effort to avoid getting in a rut listening to the same four podcasts, I began exploring other options.  I began with Creative Mornings and speaker Seth Godin.

Friends, are you trying to make a dent in the world? Are you trying to do work that matters? Work that fulfills you? Then watch the videos linked below now. I realize they are marketing and design focused, but these matter to you as a parent, an educator, a human being who is wanting to create or encourage the children in the world or yourself to create.

As I began listening, these two quotes from Seth Godin in these talks struck a me deep in my soul – and not in a good way:

…What they [industrialists] needed from workers were people willing to sit still for 10 hours, use a number 2 pencil, and follow instructions.

We were trained from the time we were three to ‘Do what we were told’“.

I don’t know about you, but I don’t want that. I don’t want that for my son. I don’t want that for our classrooms. I don’t want that for teachers teaching. I might have lofty goals  to #takebacktheclassroom and #takebacklearning but I believe our teachers and students have the right to learn in creativity-fostering, safe environments. It’s why we believe in Maker Spaces so much here at Brain Brigade. It’s what we live, think, breathe, feel, make, do. We help other teachers build Maker Spaces in their classrooms. We help homeschoolers build Maker Spaces at home. We make at home in our spare time and encourage our children and family members to ask, think, question, explore and more.

Watch & listen to Seth Godin here and then listen closely to his Q&A, and then if you can’t get enough, check him out on this podcast station. While in the Q&A a person asks a question specific to education at 16:50. LISTEN to it. {Here’s the manifesto Stop Stealing Dreams he refers to}.

Create an environment where not only is it safe to fail, but it is required to fail.” Seth Godin

Are you doing that for your students? Are you allowing them to fail? That is what a Maker Space is all about. Students must fail. They must take risks. And our job as educators is to create an environment that is safe for our students to fail. That’s it. It’s why we do what we do.

It’s how we’re taking back our classrooms. It’s how we’re exchanging those number two pencils for hands on learning. It’s how we’re breaking the mold and how we want to help you break that mold in your own classroom and world.

What’s keeping you from scary work? What might get you fired? Run out of town? Encourage you to take risks? If you don’t know where to start, then contact us using the form listed on the About Us page. We want you to you be confident in changing your classroom and changing your world.

Maker Spaces: Appleton Maker Space Tour

Last week I traveled to Appleton, Wisconsin and visited the MakerSpace located there. It was located in a small building behind a hair salon. It is a great place for members to tinker, fabricate and collaborate in making projects that appeal to them. Each month members pay a fee to have access to all of the equipment, materials and storage located in the space. The president of the organization, Chris, gave me a tour. There were several large work areas for woodworking, metal work, electronics, planning and storage. All were equipped with the machines for an inventor to do hands on learning.

A maker space is a great space to have access to all of the various machines needed to invent at a fraction of the cost of purchasing these on your own. There were lathes, saws, planers, welders, drill presses, and many more machines that could be useful for anyone wishing to be creative. I really liked their planning room that had a floor to ceiling whiteboard that was 12 feet wide and 8 feet wide. Members can use the board for drawing, creating lists or planning a project.

Chris introduced me to one of the members who is building an airplane in the space. He had the frame and wheels already made and was working on the wings. It reminded me of the old days when early flight pioneers made airplanes in their garages.

Craft Stick Truss Bridgeu

These are the kinds of spaces that we need in schools! We don’t need
all of the fancy and expensive equipment, but we do need areas where students can invent, create, fabricate, and experience failure and success. A corner of a classroom with craft sticks, glue guns, wires, light bulbs, and any number of inexpensive items helps children use their hands and minds to invent. Let’s get away from this culture of constant testing and get back to the real world!

Hydroponics 101.4: Light Requirements

Hydroponics-101

I’ve been growing plants using hydroponics for a few years now, both at home and in the classroom. For the first several years of doing hydroponics and aquaponics systems, I used a bank of T-5 fluorescent bulbs and they worked okay. But in this last planting, which I have set up in my basement, I purchased a bank of LED lights. I am passionately green and I read that LEDs are much more energy efficient and last much longer than any other type of bulb. I also read that LEDs can be tailored to provide the exact wavelengths of light for plants and flowers. You see, plants love light from the blue and red ends of the spectrum. While fluorescents provide some of that light, much of a fluorescent’s light is white and that is a waste of energy because plants use very little white light.


We’re currently in a series exploring Hydroponics {read our previous entries 101.1, 101.2, 101.3}.


The bank of LEDs was about $275 dollars. This was comparable to the cost of a T-5 bank of fluorescent bulbs, but I was astounded at the small size of the LED bank!

T5-and-LED-Light

I was blown away by the light though! What the LED bank lacked in size, it more than made up for in intensity. The instructions stated that the light should be hung at least 24 inches above the plants. I was able to hang it at about 22 inches. I was stunned that the light covered an area of about 2×4 feet where the plants were located. This from a bank of lights that is five inches wide and 18 inches long! My fluorescent bank was 22 inches wide and 46 inches long.

I left the light on while I worked in the basement. After about 15 minutes I started to see everything in a green aura. The intensity and wavelength of the light was affecting my vision. I decided to turn off the light and construct an enclosure around my plants that had Mylar reflective material on the sides to reflect the light back on to the plants.

My plants are now bathed in blue and red light and are growing wonderfully.

Oh, and my vision is back to normal.
