PoCoOpolis 500 Static Lab
Kelsea and Nisrene
Purpose: to test which two items when rubbed together create the highest static charge, measured by amount of hole punches the object picks up.
Hypothesis: rubbing the ebony and polyester together will create the highest static charge.
Procedure:
Take a piece of material and rub it with another.
Attempt to pick up hole punches with item.
Repeat process.
Materials:
Wool
polyester
fur
Lucite
plastic spoon
paper hole punches
ebony
plastic bag
cotton
plastic straw
| Object one | Object two | Results |
| Wool | Lucite | 18 |
| Wool | Plastic spoon | 14 |
| Fur | Lucite | 32 |
| Ebony | Wool | 29 |
| Plastic straw | Wool | 20 |
| Cotton | Ebony | 26 |
| Lucite | Plastic bag | 16 |
Observations: how firmly rubbed together tended to make static charge weaker. Fur tended to be most successful with other items.
Results: rubbing fur and Lucite together creates the highest static charge.
Conclusion: our hypothesis was proven to be incorrect. Fur and Lucite rubbed together attract the most paper hole punches. If we were to do the experiment over again I would’ve taken into consideration keeping the amount of rubs more constant.
Thanks for your very complete video lab. You have demonstrated that you have a good grasp of the scientific method. I am glad you completed other parts of the lab in writing to make up for missing parts in the video. One thought is to edit the video to make it more concise and engaging. Good work!
