This is a review of static charges and the activities with the static sticks.
Please investigate forces using the apparatus and links provided as well as the Wayground and PhET activity with the sweater and balloons.

Balloons
Inflate then investigate the balloons using
hair and clothes
light stream of water from faucet
paper dots
paper roll
In the Show Your Work box, include 2 pictures of your work. (2pts)
In the answer box, please type a few sentences or list the interactions of the balloons. (3pts)
Static Tube
List 3 things you learned or noticed while investigating the static tube.
Add a photograph of a piece of fabric either attracting to or repelling from the tube.
Why do opposite charges attract?
Electrostatic force develops when ...
Please insert a screenshot from the PhET / Wayground balloon and sweater activity that shows the balloon stuck to the wall.
Can water molecules be influenced by electrostatic force?
Insert a photograph that supports your answer choice.
If these negatively charged objects could move on their own, what would they do?
The word electricity is derived from what?
Electrostatic forces from charges are always attractive forces just as gravity is always an attractive force.
What happens to the strength of the force between charged objects as they get closer to each other?
Why are the types of charges called positive and negative?
