4. What are atoms?

5. The smallest particle that makes up all matter and where are they located in the atom?

6. What are the Sub atomic particles that make up all atoms?

7. Protons:Nucleus
Neutron: Nucleus
Electron: Outer Shell

8. True or False: Opposite charges repel and Like Charges Attract.

9. False: Opposite Charges Attract
Like Charges Repel

10. Draw the atoms of a magnetized Iron Core and then a demagnetized Iron Core

12. Areas in the magnet where the atoms are aligned are called:

13. Domains

14. What is a magnet?

15. A magnet is anything that attracts iron of metals containing iron

16. What is an electromagnet?

17. An electromagnet is a magnet that is created through electricity.

18. What are 3 ways a magnet loses its strength?

19. Hitting or dropping the magnet. Change of Temperature.
Putting another magnet near the magnet.

20. Describe the purpose of the iron core with an electromagnet.

21. When the solenoid creates a magnetic field the atoms in the iron core align. Therefore, the iron core becomes a magnet.

22. Describe how increasing the number of coils affects the strenght of an electromagnet.

23. Increasing the number of coils creates a bigger solenoid therefore creating a larger magnetic field.

24. True or False Earth is one Giant Magnet?

25. True!!!

26. Why are the auroras at the north or south poles?

27. The auroras are only found at the North or South poles because there are tiny openings at the POLES

28. Describe how Magnetite was discovered.

29. Legend has it that Magnes was herding his sheep in an area of Northern Greece called Magnesia, about 4,000 years ago. Suddenly both, the nails in his shoes and the metal tip of his staff became firmly stuck to the large, black rock on which he was standing.

30. Explain what would happen if the earth did not have a magnetic field to protect us.

31. The solar particles would dry up all the water, people would get cancer and earth would begin to look like mars.

32. What would happen to our sense of direction if earth was not a magnet?

33. Birds would not be able to migrate, people would get lost.

34. What was Hans Christian Oersted’s discovery?

35. He discovered there was a relationship between electricity and magnetism. (electromagnetism). He did this by placing a wire carrying a current by a compass. The compass needle began to move.

36. What was Michael Faraday’s greatest discovery?

37. He founded that a magnet could produce an electric current
He founded that a magnet could produce an electric current. Opposite of Hans Christian Oersted.

38. What is an electric Generator?

39. An Electric generator converts mechancial energy to electrical energy.

41. Create a Venn Diagram comparing the difference between four types of magnets.

42. True or False: do different type magnets have different shape magnetic fields?

43. This is False-because during the “Shape of the Magnet” Lab we were able see that all magnets such as a horse shoe magnet when it was compared to the bar magnet-showed poles in different areas but the same patterns

44. What is an independent variable?

45. Something that is changed or manipulated in an experiment.

46. What is an dependent variable and what are constants?

47. Dependent variable: something that is being tested.
Constants: what is held the same.

48. What is the proper format of a hypothesis?

49. If…then…because statement with scientific reasoning.
