Conductor or Insulator Science Experiment

Testing for Conductors or Insulators
A few months ago I found myself at an electronics store getting a quick tutorial about all kinds of fancy gizmos and such. I went there with the intention of buying bulbs, batteries, and some wire to make circuit experiments for my students. I have wanted to make a Conductor or Insulator Science Experiment for so long! But after telling the nice man that I'm a teacher and what I was looking for, he got really excited and that's how the tutorial started.

I ended up learning a lot about all kinds of stuff and buying some really cute mini jumpers, battery holders, batteries and bulbs

Anyway, that was months ago. Since then I've been so busy with school that I had to put that project on the back burner.  It's a good thing I got a few hours and a good vibe yesterday so I finally started it and once I got started, I could not stop. I was darting from room to room rounding up my supplies and trying out new ideas along the way. Then I spotted the clipboard and everything just clicked after that.

I started by inserting the batteries into the battery holder and clamping it down with the clipboard's clip. My battery holder already came with two wires attached, a red and a black. I clamped one end of a short alligator jumper clip onto the red wire and left the other end loose. I taped the black wire to the base of the bulb which was housed in a tiny matchbox. A paperclip was wrapped around the swirly part of the bulb. I clamped another alligator clip to the paperclip and the other end of that gator clip was loose. I left the loose ends for the purpose of leaving the circuit open so that my students can test different materials for electric conductivity. The circles at the center are like holding cells for the materials to be tested. I just cut them from a tissue roll and taped them down. Then I labelled it with adhesive foam dotty letters. It finally was complete!

Every time I look at it, I feel so good inside. Crafting just makes me happy!

This looks really cool. I think it could be made into a great differentiated performance task given the right "story hook". Amazing where a simple idea will take you. Thanks for the inspiration!

This is awesome! Thank you

About Me

My photo
As a Caribbean primary school teacher, I share my unique classroom with the world through this blog. Readers step into my class through the pictures, articles and classroom samples of games and lessons used in my class. I have been teaching since 2005 at the std. 4 primary level in Trinidad and Tobago. I am particularly interested in sharing my own personal lesson plans, tests and activities. Teachers need to share ideas and support each other because in doing so, we help to educate our students and develop ourselves as teachers. Technology is ever evolving and we as teachers should get on board with it, collaborate and keep up to date with this new age that we live in. Our students belong to this technological era and we must embrace opportunities to learn from each other in this global community. I also love to express my creativity in the classroom. I am a bit of a craftster . So I'm always cutting, gluing or making something... a game, a chart, a learning center, etc. So, teachers and parents, feel free to stop by and see what's new at Nyla's Crafty Teaching!
