Question

name sophia date 12 10 23 class 3rd electricity webquest part 1: exploring static electricity directions: go to tinyurl.com/36csup6 and click play. manipulate the simulation and then record your responses to the questions below. 1. rub a balloon on the sweater and stick it to the sweater. observe what happens to the charges found on the sweater and balloon as you rub them together. fill in the chart below with your observations. describe the charges on the sweater: (+ or -) the sweater becomes positively charged as it loses electrons to the balloon during rubbing. describe the charges on the balloon: (+ or -) type here 2. why do you think the balloon sticks to the sweater? type here

Explanation:

For Question 1 (Charges on Balloon):

Step1: Recall Charge Transfer

When two objects rub, electrons transfer. The sweater loses electrons (becomes +), so the balloon gains those electrons.

Step2: Determine Balloon's Charge

Gaining electrons means the balloon has more negative charges, so it's negatively charged (-).

Step1: Identify Charges

Sweater is positive (+), balloon is negative (-) after rubbing.

Step2: Apply Charge Interaction

Opposite charges attract. So the positive sweater and negative balloon attract each other, making the balloon stick.

Answer:

The balloon becomes negatively charged as it gains electrons from the sweater during rubbing. (Charge: -)

For Question 2 (Why Balloon Sticks):
