This learning activity will be a whole group demonstration. Either print or share the jumping paper? document with the students. The teacher will explain that the balloon will come in close contact with the small pieces of paper, but will not touch them. Have a student volunteer to come up so that they may assist with the charging of the balloon. Explain that their hair will get messy and that you will have to rub the balloon on their hair. Allow the students to make predictions before the demonstration, and then write their observations and make explanations after the demonstration. The teacher will then lead a class discussion on what happened and introduce several topics, including fields and non-contact forces. Possible discussion questions include:
What would happen if we didn't rub the balloon on someone's head?
What other materials could we use to charge the balloon?
Does the amount of rubbing or "charging" of the balloon affect how much paper is picked up, how closely the balloon has to be to pick the paper up, or how quickly it is picked up?
