In this lesson, we experiment with all sorts of objects to find out what is conductive so you can start designing your own inventions. Here is a quick example of what your finished experiment will look like.

Test an item by laying it across the conductive tape traces. If it is conductive, the game will tell you! Sometimes, it helps to use a plastic ruler to press down on the item so you don't accidentally set off the conductive radar with your hands! Label the item in your t-chart as you test them!

Discussion Questions:
Discussion Questions:
- How are the conductive items alike?
- What do the insulators have in common?
- What makes a conductor different than an insulator?
- What items did you not test that you think might be conductive?
- Why do you think the alligator clips and alligator heads are covered in plastic?
