Examine:
We figured that the fur worked the best for each material. It had the quickest reaction with the spoon. When we rubbed the fur against the spoon the fur was giving the spoon electrons. The spoon now had a negative charge. When we put the spoon against the piffball it was attracted to the spoon. Because the spoon had electrons that the ball didn’t have so the ball took the electrons. When you take the spoon away and put it near the ball, the ball rejects the spoon. Because the ball now has the same amount of electrons from the spoon. So they are not attracted because they have like electrons.
We chose the spoon and fur and lucite and fur for the race.
You have included some great information in your post. I appreciate the table of results you added. You didn’t need to include the collaboration plan. You needed to examine the collaboration though. Pictures would help get your message across. Good work, though.
