3 C. lightning

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. D. Rubbing the balloon makes it a battery, and this makes it attracted to the wall. 4

4 A. Rubbing a balloon charges the balloon, and this charge is attracted to the wall. Home

7 A. repel

8 How can you tell when static electricity has been discharged? A. The object begins to spin rapidly when it is shocked B. Static electricity gives off many different colors C. Light is released and you can feel a shock D. Heat is released and can be felt

8 C. Light is released and you can feel a shock

9 Which of the following "I Wonder..." statements would explain the connection of static electricity to lightning? A. I wonder is there more voltage in a lightning bolt that hits land or one that hits water. B. I wonder if the hairs on a person's arm or head really stand up when lightning is about to strike. C. I wonder if lightning is seen better from the shuttle in space or standing on the surface of the Earth. D. I wonder if certain animals really start acting strangely just before lightning strikes, like dogs barking wildly.

9 B. I wonder if the hairs on a person's arm or head really stand up when lightning is about to strike.
