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!

You Want to Start a Maker Space. Now What?

You’ve read some blogs, maybe even read a book or two, you follow some insta feeds, and everywhere you go the term “Maker Space” seems to pop up. Hands-on learning is your style. You might even be a little out-of-the-box. Maybe you’re a lot out of the box! You desire to help your students learn how to problem solve and think creatively and be curious. You’re ready to jump in and start a Maker Space in your classroom or school. But where do you begin? Do you need a 3D printer? How big of a space do you need? The beauty of a Maker Space is that there are no rights or wrongs. The challenge of starting a Maker Space is that there are no rights or wrongs! Get my drift? It’s your first Maker Space challenge andyou haven’t even started it up! Get ready, because you are about to grow!

Creating a Maker Space can be something as simple as a small table or desk in a corner of your room. A Maker Space can be as elaborate as a dedicated room or bigger! If you have the space. Determine who will be using this space. Is it your classroom only? You might be collaborating with your other grade level teachers so a dedicated location like a commons area or maybe multiple small stations in multiple classrooms might be the solution. Don’t be afraid to think creatively and be flexible.

Once you have a location figured out you can start it up! It’s okay to start small.  You don’t need a 3D printer make your Maker Space come alive.  Collect clean recyclables and get some bins to sort them in. In fact, if you see a sale on bins, buy more. {You can thank me later!} Make tools available to your students {glue, scissors, a hole punch, scotch tape, masking tape, duct tape, maybe some small hand tools, hot glue gun}. Other materials such as string, craft sticks, pom poms, pasta,  straws…. Let your students start exploring when they have some down time or indoor recess.

Teach your students how to use tools responsibly. Wear safety glasses if needed. We have a five year old who uses the hot glue gun to glue and an eight year old who also uses a hot glue gun to glue and weld! Know your students and let them take on some responsibility and calculated risk. Chances are, many other students will quickly display their ability to be mature when the reward is good!

Once your students are familiar with the Space, offer them challenges. How tall can you build a tower? Build a bridge and see how much weight it can hold. Build a car and see how far it can roll down a ramp.

Confessions of a Maker Space Volunteer: Day 1

I started volunteering in the Maker Space at my son’s elementary school a few weeks into the school year. The students had already begun their projects. Their challenge? To design a toy. They had researched and designed their projects on paper and had begun the building phase using engineering design principles. My first morning, the Maker Space teacher/hero, Mrs. H, introduced me and then set me free to the kids. I thought I knew what I was getting into. I was in the risk taking zone. And in that moment, I was afraid of failing.

I knew some of what a Maker Space is because I had been in my dad’s Maker Space at his school a handful of times before he retired. I knew and understood and completely agree with the philosophy of a Maker Space. I had never actually been the one to troubleshoot with students. My own son, yes. My niece and nephew, yes. But to troubleshoot a classroom full of kids? Field their questions? Prioritize requests for help from what felt like ten groups at once!? Everyone needed something from me (or Mrs. H) and I dove in.

Let’s back up a bit. Mrs. H made me out to be waaaaay more of an expert than what I really am. I mean, look at me! I’m a mom in my 30s. Sometimes I wear glasses to make me smarter. Did Mrs. H really think that I should be in this room helping innocent children!?

do-these-glasses-make-me-smarter

Do glasses make me smarter?

I looked at those fourth graders and fear swelled inside my soul. I dove in. I started looking at projects. I began troubleshooting. My first intimidating task: a student needed a hole drilled in wood. I’ve never done that on my own before. Always with the help of my dad or my husband. But I knew how to put a drill bit in. And I knew how to use the drill. So I tackled it. And I did okay. And the student was thrilled!

Before I knew it, 50 minutes was gone. Mrs. H rang a bell, and the kids reluctantly gave up their work and started furiously cleaning up every surface in the room. {Side note: Impressive, Mrs. H. Impressive.} The floors swept, the tables cleared, students lined up and filed out.

Five minutes later, a class of third graders filed in, pulling projects from their silver rack. And we began again. This time, I had a touch of confidence. I had just drilled a hole. I know, pretty amazing. I was feeling good. Until a kid came to me with a 10 foot piece of wood, two inches thick, and 10 inches wide and asked me to cut it.

I had no idea how to use the clamps right, so I asked Mrs. H. She showed me how. I started sawing. The line was crooked. I stopped sawing. I showed the student how to measure to create a straight line (now, that, I taught like a boss!). And I started sawing again. Soon the only sound in the room was the little hand saw chewing through the wood. All eyes were on me. If you’ve never spent time in a Maker Space, it’s NEVER QUIET. But it was silent. Back and forth. I sawed. And sawed. And sawed. Kids started making noise again. Finally, the board hit the tile floor. And the kids started clapping.

I can’t make this up. They clapped. I laughed.

I’m still laughing while thinking about it.

I was hooked. I spend four hours each week in the Maker Space. I wish I could spend the entire day there. My confidence is growing.  And so are my skills. But what’s even better, I’m watching the confidence increase in the students. I’m watching them wrestle with a problem and work through solutions. It’s an exciting place. Terrifying at times, but it doesn’t take long to get past that.

Aquaponics 101

Adding-Tilapia-to-HS-Hydroponics

I’m assisting Oconomowoc High School with the aquaponics system in their greenhouse. So far we have set up two systems with 50 tilapia in one tank and 50 perch in a second tank. We are facing some challenges with our systems from the heat that is building when the outside temperature reaches 70 degrees or above. Tilapia need a water temperature of about 80 degrees, while perch need a water temperature of about 70 degrees. Our greenhouse reaches over 90 degrees and can see temperatures of 110. Before the weather gets too warm we need to find a way to keep the water cool enough for the fish to survive. Enter Travis. Travis is a second shift custodian at the high school and has significant experience in building aquaponics systems. I sat down with him over lunch the other day and was very impressed by his knowledge and experience. Travis has a high school diploma but has so much knowledge that I thought he had a college degree. Travis has had much hands on experience fabricating and problem solving over 150 aquaponic systems. I asked Travis if he had a degree. His response was that he just had a high school diploma but he picked up a lot of money and expertise doing side aquaponics jobs. He also has sought out many experts and used collaboration to build his knowledge.

Our discussion just reinforced my belief that we need more individuals with the ability to fabricate, and to use their hands to build projects that solve problems. I’m very impressed by his ability to think out of the box. After about an hour of talking, we had a solution to our overheating problem. It struck me that what Travis is doing is just the thing I want my students to do. Think out of the box, collaborate, seek expert advice, problem solve. The world could use more people like Travis!

Being Too Busy is Really Being Greedy

Mrs.  Brainiac back with the answer to last week’s math problem. Last week, we discussed how Jolene Brainiac has been nagging Mrs. Brainiac to post her Friday blog updates. “Come on, Mom. It’s not that hard to share some creative thoughts about Maker Space and science projects, maybe something about turning failure into success or how to engage kids’ natural curiosity about science by providing meaningful activities that spark enthusiasm about learning.”

Blah, blah, blah, Brainiac Jolene.

The common denominator is “H” which stands for Husband Brainiac Jerry. So, even though I freed up a great deal of time by eliminating a bunch of other activities, I still have the Head Brainiac around. So, we have been traveling, working on Brain Brigade projects, bike riding and pretty much just having a good old time.

I hope this explains why I was too busy to post my blog. I was having Too Much Fun.

The blog wasn’t the only area of my responsibilities that was neglected due to having Too Much Fun. I forgot to empty the kitchen compost container and it sort of took on a life of its own.

So how do we get away from all this talk of being too busy and overwhelmed by all our activities and responsibilities? How do we slow down and smell the roses?

Part of the problem is we need to “learn to say no.” We all know that already but yet we continue to say “yes.” Let’s delve into that. Why is it so hard to say “no” when someone asks for help with a project, or to volunteer for an activity or even just to meet up with the girls and have coffee? We say “yes” and then spend the next week complaining or stressing that we should have said no. We even say, “I need to learn to say “no.””

Revelation coming: We don’t say “no” because we really do want to do whatever it was! True! We want to do those things, whether volunteering for a worthy cause or visiting with friends. What we don’t want to do is spend our valuable time doing these things. Confused?

Let me say that again. We actually do want to volunteer at the local charity fundraiser. But we want to sit around and watch TV or read a book more than we want to work at the fundraiser. And, you can’t have it all.

The reason you can’t say “no” is because it’s stuff that matters. So, we need to “learn to say no to the things we want to do.” Not all of them, but enough that we can de-stress and relax a bit.

It’s sort of like wanting too many things (being greedy). I think we can probably agree that it’s okay to want things, a nice car, decent home, a meal out once in a while. But can we all agree that we shouldn’t get everything we want? If we get everything we want, we would have nothing to look forward to. We already have it all. It’s GREEDY.

It’s the same thing with wanting to do all the activities that are available to you (again, being greedy). So go ahead and do some volunteering, read some books, hang out with friends or family. But realize that sometimes you have to say “no” to the things you want to do in the interest of getting to ENJOY the other things you are doing. Don’t be GREEDY.

And right now, I’m enjoying writing this blog. And I said “no” to something else I wanted to do (which was making myself a snack). And next time I tell you I’m too busy, feel free to tell me to quit being greedy.

Child Labor Laws-Repeal Them NOW!

My sincere apology. Mrs. Brainiac, the long-suffering better half of Brainiac Jerry, is here today to offer a huge apology. I promised Jolene Brainiac I would faithfully write a blog every Friday about creative tinkering, maker spaces, science, engineering, STEM or other engaging hands-on learning activities. Whoops. The last two weeks I neglected this important duty and Jolene Brainiac is on my case to get it done, so here goes.

I don’t want to make excuses for why I didn’t post my blogs, I just want to EXPLAIN. I’m not sure what the difference between the two is, seems like explaining why I didn’t do it is the same as making excuses but in the interest in getting this blog on the road, let’s continue on.

I’m busy. Really busy. I know everyone says that, but I really am busy. Yes, my four kids are grown up and on their own so that should save me some time. And I sold my house and bought a condo so my yard work is done for me. And I don’t volunteer for the fire department since I moved to my condo. I work more regular hours than I used to, not so much overtime.

Finn Does ALL of Grandma Brainiac's work. Finn wonders why Grandma is so busy.

Finn Does ALL of Grandma Brainiac’s work. Finn wonders why Grandma is so busy. She should use a stopwatch to keep on schedule like Finn does.

So, why am I so busy? Don’t know. Seems like the fewer activities and events I’m involved in, the more busy and frazzled I am. I’m guessing there is a math lesson here somewhere, like “if volunteering (V) plus working (W) plus kids (K) plus overtime (OT) plus cleaning (C)  plus husband (H) equals busy (B), then having less V, W, K, OT and C but the same amount of H should equal less then B.” And yet it equals 2B.

So, what is the common denominator here? And why am using a math metaphor in a science blog?

Let’s look at those equations again.

Equation one: V+W+K+OT+C+H=B

Equation two: H=2B

Comment on this blog post if you think you can explain how these two equations correlate to Why I’m Too Busy to Post My Blog Every Friday Like I Promised.

The explanation will be published in my blog next week. If I’m not too, well, you know.

Air Pressure Experiments (IV): The Big Can Crush

I have a series of air pressure experiments (Air Pressure I – The Small Can Crusher, Air Pressure II – Prank, Air Pressure III – AnticsBernoulli’s Principle), that I’ve done over the years that always amaze my students. I have fun doing these, too. I think when I enjoy a classroom demonstration, my students tend to enjoy it more and participate more, too. Our air pressure science experiments are hands on and applicable to real life. Plus, they’re impressive (or hilarious – check out Air Pressure Prank and Air Pressure Antics). These science activities gets students thinking about air pressure which is an ambiguous concept for students to grasp. We take air pressure for granted. We don’t think about it very often. We notice it in our bags of chips when we’re flying on an air plane. We notice it in the wind and weather. But overall, it’s not as obvious as it is with this Big Can Crush experiment.

What this video doesn’t show are the steps we took before doing this demonstration. We used a clean can, marked square inches, discussed various math concepts like square units and cubic units, and of course air pressure! We heated up some water in this can, removed it from the heat and screwed on the cap. What do you think will happen? Most of my students think it will explode!

Watch what happens:

Air pressure is a force acting on us and in us every moment. If it wasn’t for air pressure in our bodies we’d flatten and crumple like this can! Check our bundled download to try all of these experiments in your own classroom.
