Our project so far was to find out which combination of materials could attract a cork the best. In the video below, I rub a plastic spoon with fur. The result is that t he spoon attracts the cork. When I rub the spoon with fur the electrons from the fur transfers to the spoon. Since the cork is neutral, it will be attracted to the spoon
After the cork has gained electrons and the spoon loses most of its electrons, the spoon will actually repel the cork, showed in the video below.

Many aspects of the collaboration went well. We were able to find information that was able to help us advance to the next step. We had a general idea of what our plan was. Some things that didn’t quite do so well, was the amount of distractions around the room. Others talking to our group off-topic and vice-versa. It was partly my job to put an end to this, but sometimes, a group member is going to do more work than others, and in my case, that’s okay. I was able to make my group take a step back and approach our plan in a different way. Our group was now focused on our task and we ended up with the table above showing how all the materials reacted with the acetate.
One thing that I would do differently or consider is spending more time making sure that my group members were really going to help me on the project. I feel that if I chose different partners, the project would go completely differently. Maybe one or two group members needed a reminder to stay on task, but that shouldn’t have been the case in the first place.
Another thing I would do differently is maybe doing some more research on how to efficiently test how the materials would react to the acetate. Many groups (including mine) didn’t know that they had to zero the acetate/cork and many didn’t ground themselves when testing, remaining on their chairs and leaning their elbows on the table. In the event that I will be testing charges on objects once again, I will remember to take what I’ve learned from this project and apply it to what I would currently be doing.
