Open Ended

When have you been zapped or shocked by something? What happened for you to feel it?

Static Electricity

• Electrons are a part of atoms (makes up stuff) that can move

• The sudden movement of charges is the ZAP you feel

• The build up of electric charges (electrons) causes objects to produce a force

Charged objects

• When an objects gains electrons, it becomes more negative

• When an object loses electrons, it becomes more positive

• If an object has the same amount of positive charges as negative charges, then it will be neutral

Charged objects

Objects may pick up electrons to become negative, or lose electrons to become positive. Or, if they have an equal amount of + and -, they are neutral

Multiple Choice

If an object gains electrons, it will be...

• positively charged

• negatively charged

• neutral

Interactions between charges

• Charges that are like (both positive, or both negative) will repel - or move away from each other.

• Charges that are different will attract, or move near each other

Multiple Choice

Two objects that are both positively charged will

• attract each other

• repel each other

• do nothing

Multiple Choice

Two objects that have opposite charges (one positive, one negative) will

• attract each other

• repel each other

• do nothing

Multiple Choice
