Thanks to the science staff at Kichuimen Academy, we were able to use a Van De Graaff Generator this morning. (Miss Mullin rehearsed last night!) We used a range of accessories (and three brave volunteers) to demonstrate the basic properties of static electric charge. These properties are:
- Like charges repel
- Static charge tends to reside preferentially on points
- Static charge is generated by frictional contact between certain pairs of insulating materials
We could see and hear the static electricity at work! Our volunteers described it as “like a breeze going through your body.”
Mums and Dads – do you remember doing this at school?
