1 Electricity and Magnetism Study Guide Ms. DeSimone Fourth Grade, Room 221 Test Dates: 4D 4D: Wednesday, March 12 th, D3 4R 4R: Thursday, March 13 th, D4

2 Let’s start with… Electricity pg. 562

3 True or False True or False: It is not possible to see, smell, or weigh an electrical charge.TRUE! pg. 564

4 Fill in the blank: Electrical charges can be ______ or ____________. A. north or south B. hot or cold C. attract or repel D. positive or negative pg. 564

5 What is static electricity? Is it… a type of circuit? the difference between a north and south pole? a buildup of electric charges on an object? the way that power flows through wires? pg. 565

6 What is a circuit? The path along which electric current can flow OR… The flow of electric charges through a circuit pg. 567

7 What is a discharge? The sudden movement of electric charges from one object to another. You have experienced a discharge if you have ever touched something and gotten a SHOCK! pg. 566

8 What are the two main types of circuits? Series Circuit Parallel Circuit pg. 568

9 Explain how series circuits and parallel circuits are different. In a series circuit, electric current flows in the same direction along a single path. In a parallel circuit, electric current flows through more than one path. pg. 568

10 Now, let’s move on to… Magnetism pg. 574

11 What are the two types of magnetic forces? ___ ___ ___ ___ ___ ___ ___ and ___ ___ ___ ___ ___ ANSWERS: attract and repel pg. 576

12 When two magnets pull or push away, we say that they ________ one another. R E P E L

13 When two magnets pull together, we say that they _______ one another. A T T R A C T pg. 576

14 Which of the materials listed below do magnets attract? copper nickel tin steel cobalt iron plastic wood pg. 576

15 What are the ends of magnets called? POLES pg. 577

16 Name each type of magnet shown below: pg. 576

17 What is the area of magnetic force around a magnet called? A. magnetic strength B. magnetic field C. magnetic ends D. magnetic tips pg. 578

18 What is an electromagnet? An electromagnet is a magnet formed when electric current flows through wire wrapped in coils around an iron bar. pg. 581

19 Electromagnets can be found in your house. Name some places where they can be found. headphones telephones doorbells motors There are many! Can you think of any others? pg. 581

20 BONUS QUESTION There will be a 2-point BONUS question on your test. It will be about one of the Science labs we have done. Our labs included:  Balloon Static  Stick or Won’t Stick  Making Parallel and Series Circuits  Magnets’ Ends  Lines of Force with Iron Filings

21 ~ THE END ~ PLEASE GO STUDY!
