4. Column 1, #1 Give an example of current electricity. Turning on a flash light.

5. Column 1, #2 Who invented the lightning rod and what was its purpose. Ben Franklin designed the lightning rod to draw electricity back down into the earth.

6. Column 1, #3 The north and south poles. What are the ends of a magnet called.

7. Column 1, #4 What is the name of a natural magnet found in the earth. Magnetite.

8. Column 1, #5 Opposites attract. When you line up like poles of a magnet, they repel each other. What happens when you try to put like poles of magnets together?

9. Column 2, #1 The flow of electrons. Any path along which electrons can flow. What is an electric circuit?

10. Column 2, #2 It is a measure of how much a material opposes the flow of electric current. In electricity we have conductors, insulators, and resistors…What is resistance, in terms of electric currents?

11. Column 2, #3 Unlike charges attract, and like charges repel. How do the charges of electrons and protons interact in electricity?

12. Column 2, #4 A conductor – metal, water What do you call a material that allows electric current to pass through easily? Give an example.

13. Column 2, #5 What do you call a material that does not let an electric current pass through easily? An insulator - glass, wood, rubber, plastic

14. Column 3, #1 Static electricity is the build up of electrons. When a balloon is rubbed on clothing extra electrons are added and the balloon becomes negatively charged. The negative charges are attracted to the positive charges on the wall. What is static electricity? Give an example.

15. Column 3, #2 Give an example of electricity and magnets being used together to perform a daily function. A door bell, telephone, computer, television, maglev, etc.

16. Column 3, #3 What is the device called that allows you to turn a circuit on and off? A light _____. A switch!

17. Column 3, #4 A series circuit contains a couple of objects along a single path. A parallel circuit connects several objects in a way that the current for each object has its own path. What is the difference between a series circuit and a parallel circuit?

18. Column 3, #5 In a series circuit, the 2nd light bulb is out because the circuit is open. In a parallel circuit, the 2nd light bulb is on because it has its own closed circuit. If you have a circuit with 2 light bulbs, what happens to the 2nd light bulb if the first light bulb in a series circuit is loose; what happens if it is a parallel circuit?

19. Column 4, #1 What is a magnet and give an example of when we use them? A magnet is anything that pulls iron, steel, and certain other metals together. Examples are magnets on the refrigerator door & the refrigerator door.

20. Column 4, #2 Attraction What term describes a magnet’s ability to pull things towards it - attraction or repulsion?

21. Column 4, #3 Repulsion What term describes a magnet’s ability to push things away – attraction or repulsion?

22. Column 4, #4 Electricity What can you make from magnets? Think about an electromagnet…

23. Column 4, #5 What happens to a coil of wire when you run electricity through it? What is it called? Remember our classroom demonstration… It becomes a temporary magnet & is called an electromagnet.
