My class was instructed to do a race of using static electricity to repel or pull rulers in circles and racing one another. We had to chose a popular brand and a car company as our sponsors and use two e”engines” for the race. We chose both engines to be straw and fur.
Before the race we interviewed our drivers for their input on this upcoming event.https://sd43-my.sharepoint.com/personal/132-tjang_office43_ca/_layouts/15/guestaccess.aspx?guestaccesstoken=76PNEL7WSpVtFrdP2z1I%2bdVrAcF5gH33PXQlR2zkUrI%3d&docid=2_1ae4710def1a0489590c0a3f539c37d85
Here is a video to show what we was happening during the race.

The overall science about it was to have the straw steal electrons from the fir and when the straw was close to the wood, because it was neutrally charged, it used its protons to attract it to the straw. Overall I believe that we chose good engines but we could have chose better if we tried more combinations. Thanks.
