• During a conductivity experiment, some groups of students marked 'yes' but one group marked 'no' when they tested the pencil lead. Which of the following would be best for this group to do? 1.Change their response to 'yes' to be just like everyone else. 2.Retest to investigate the pencil lead's ability to conduct electricity. 3.Insist to the teacher that they are right and everyone else is wrong.
2.Retest to investigate the pencil lead's ability to conduct electricity.

What makes a rubbed balloon seem to “stick” to a wall? A.Rubbing a balloon charges the balloon, and this charge is attracted to the wall. B.Rubbing a balloon charges the balloon, and this charge is repelled by the opposite walls. C.Rubbing the balloon makes it magnetic and this makes it stick to the wall.
A.Rubbing a balloon charges the balloon, and this charge is attracted to the wall.
