Answers
1. A parallel circuit has more than one path for the electric current to flow through, but a series circuit only has one. 2. Atoms are neutral as there are equal numbers of protons and electrons. 3. Electric forces hold their electrons in their orbit around the nucleus of an atom. 4. Insulators are the Non-Metals on the periodic table. 5. Conductors are the Metals on the periodic table. 7. Voltage is measured in volts. 8. Current is measured in amps. 9. Resistance is measured in ohms. 10. Two electrons and two protons repel when next to each other, their force is weak. 11. An electron and a proton attract to each other, their force is strong. 12. The current increases. 13. The electricity gets rid of the excess electrons when an object is negatively charged. 14. copper, gold, aluminum, silver, and silicon 15. non metals 16. The Earth 17. Old Christmas Lights

Questions
1. What is Static Charge?

a) A charge that occurs between two objects when they come in contact with water. b) An imbalance of ions due to rubbing two objects together causing the transfer of electrons. c) An imbalance of electric charge due to rubbing two objects together causing the transfer of electrons. d) When a light-bulb in your household, or on your Christmas lights, blows out.

2. What do Electric Forces do?

a) Hold the electrons in orbit around the nucleus of an atom. b) Separate the cations and anions in water. c) Provide electricity in household lights or electronic devices. d) Allow electrons to run through wires easily.

3. What is an insulator?

a) A toaster. b) A material where electrons DO NOT easily move from place to place. c) A material where electrons DO move easily from place to place. d) The wires inside of a T.V.
