2. Chapter 7: Static charge is produced by electron transfer Pages 226-247 2

3. 3.01 Explain the production of static charges in some common materials What causes static charges to build-up in objects? Name some common examples of static charges that you have seen at home. 3

4. 3.01.1 Recognize that electricity is an integral part of our lives. Discuss how electricity influence our lives. Discuss current electricity in the classroom 4

5. 3.01.2 Define static electricity  Electric charges that can be collected and held in one place.  Stays until it jumps to a new object 5

6. 3.01.3 Differentiate between static and current electricity using operational definitions. Static Electricity Build-up of electric charges on an object Current Electricity continuous flow of charges through a complete circuit 6

7. 3.01.3 continued… 7

8. 8 3.01.4 Describe the types of charges on objects. Positive

9. 3.01.5 Describe how the charges on objects can change. Neutral objects can develop a positive charge if the object loses an electron. 9

10. 3.01.5 continued… Neutral objects can develop a negative charge by gaining an electron. 10

11. 3.01.5 continued… Positively charged objects can become neutral by gaining an electron 11

12. 3.01.5 continued… Negatively charged objects can become neutral by losing an electron. 12

13. 3.02 Explain the production of static electrical charges in some common materials Note: Negative charges (electrons) move readily whereas positive charges (protons) do not move. Demonstrate Van de Graff 13

14. 3.02.1 Define electric discharge The removal of an electric charge from an object. Examples: Lightning Rubbing feet across carpet Clothes from a dryer 14

15. 3.02.2 Define the coulomb (C) The unit of electric charge. It takes the addition or removal of 6.25 x 1018 electrons to produce 1C of charge. Similar to the number of electrons that pass into a 100 watt light bulb in one second. 15
