wood

Static electricity can "jump" from the charged object to another object, causing . .

static cling (objects sticking together)

electric discharge (and a shock!)

• static cling (objects sticking together)

• electric discharge

  (zap/shock)

• white sparkles

• heat

Negative charges gather near the base of the cloud, while positive charges build in the top of the cloud. Those negative charges at the bottom are sometimes attracted to the positive charges on the ground.

What can this cause?

When electrons move from you to the other object. You get a shock.

Select the picture that represents static discharge.

You brush your hair. Then, you put the comb or brush near the hair and it 'stands up' towards the brush without touching.

Two balloons hang from strings. They attracted to each other and touching.

What can you infer by the way the balloons are hanging?

• Both balloons have positive charges

• Both balloons have negative charges

• Neither balloon has a charge

• One balloon has a positive charge, one has a negative charge

 Timmy’s teacher hung a negatively charged balloon from the ceiling. He then asked the class what they needed to do to a second balloon in order for the two balloons to repel each other. 

What should Sandy’s class do to the second balloon in order for the balloons to repel?

• Take protons away from the second balloon to make it negatively charged

•  

  Take electrons away from the second balloon to make it positively charged

• Add protons to the second balloon to make it positively charged.

• Add electrons to the second balloon to make it negatively charged.
