The document discusses different types of electrical circuits including closed circuits, open circuits, series circuits, and parallel circuits. It provides examples of each type of circuit and explains how they work. Key points covered include how closed circuits allow current to flow, open circuits prevent current from flowing, the differences between series and parallel circuits, and examples of common circuits like flashlights, lamps, and electronics. Safety tips for lightning are also presented.

5. The reason it worked because the circuit was not open, and the current could flow.

6. It glowed because the resistance of the filament. This resistance causes the filament to get so hot that it glows. The air in the bulb is removed so the filament doesn't burn. http://www.bing.com/images/search

9. It works because there are no open circuits because they are all closed, which therefore, it causes it to work.

10. But however, if there is any closed circuits, it won't work. HTTP :// workingwomen /images/search

13. Some examples:

14. Work sheet

15. Tooth pick

16. Rubber band. HTTP :// workingwomen /images/search

18. Some examples:

19. Key

20. Brass fastener

21. Paper clip

22. nickel HTTP :// workingwomen /images/search

24. This is called a series circuit. You can use a series circuit if only want 1 light blub to shine.

25. Examples:

26. Night light

27. Mini lamp

28. Bedroom light HTTP :// workingwomen /images/search

30. You can use a parallel circuit if you want more than 1 light blub to shine!

31. Examples:

32. TV

33. I pad

34. phone HTTP :// workingwomen /images/search

37. I you take 1 light bulb out of the series circuit, the other one goes out. If you take a light bulb out of the parallel circuit, the other one stays on. This is because the series circuit only has 1 path through but parallel has 2.

41. DON'T go ANYWHERE near a window!

42. DON'T wear jewelery !

43. UN-plug ANY TV , charger , or ANYTHING the can get plugged in or your house will catch on fire! HTTP :// workingwomen /images/search
