2 A piece of iron wrapped in wire that carries an electric current

3 What is an electromagnet?

4 The difference between a bar magnet and an electromagnet

5 What is an electromagnet needs electricity to be magnetic and a bar magnet does not?

6 Two ways to increase the strength of an electromagnet

7 Add more coils or increase the voltage of the power source

8 An electromagnet is only magnetic if it has an _______ passing through its coils.

9 Electric current

10 What would be the effect of a scientist adding a second battery to an electromagnet?

11 The electromagnet would get stronger.

12 A continuous flow of negative charges.

13 What is current electricity?

14 A path along which negative charges can flow.

15 What is a circuit?

16 A material that allows electricity to pass through it easily.

17 What is a conductor?

18 A material that does not allow electricity to flow through it.

19 What is an insulator?

20 When it is open it does not allow electricity to flow through the circuit.

21 What is a switch?

22 The build up of electrical charges on a object.

23 What is static electricity?

24 When static electric charges jump off a charged object.

25 What is an electric discharge?

26 This rule explains why your hair “sticks up” after you comb it on a winter day.

27 What is like charges repel?

28 Rubbing an object with wool causes these charges to move to the object.

29 What are negative charges ?

30 These charges do not move.

31 What are positive charges?

32 A metal rod

33 What is a conductor?

34 A copper candle stick

35 What is a conductor?

36 Tires on a car

37 What is an insulator?

38 Water

39 What is a conductor?

40 A number 2 pencil.

41 What is both- conductor (the lead) and insulator (wood)?

42 A type of circuit that has only one path for electricity to flow.

43 What is a series circuit?

44 A type of circuit that has more than one path for electricity to flow.

45 What is a parallel circuit?

46 If you unscrew a bulb in this circuit all of the bulbs will go out.

47 What is a series circuit?

48 In this circuit, if you unscrew a bulb the rest will stay lit.

49 What is a parallel circuit?

50 This is used to open or close a circuit.

51 What is a switch?
