1. Electricity Lesson 1 Forces and Electrical Charges

2. A. Everything is made up of atoms. An atom is made up of protons, neutrons, and electrons. Protons have a positive (+) charge, electrons have a negative (-) charge, and neutrons have no charge.

3. B. Atoms can gain or lose electrons. Extra electrons give the atom or object a negative charge. Losing electrons make the object have more protons than electrons so it has a positive charge.

4. C. Objects can be charged by rubbing them together.

5. D. Objects with like charges repel each other, while objects with opposite charges attract each other.

6. E. Static means staying in one place, not moving.

7. F. Static Electricity is a build up of electrons of a substance, making a negative charge.
