Directions: Fill in the blanks
17. The molecules in a gas do not stay close together.
18. When paper is turned into ash, this is an example of a chemical change.

water____________.
20. When the sun shines on a parking lot, thermal energy is ______added to the parking
lot_______________ .
21. When solid iron is melted, thermal energy is ____added____ the iron.
22. When thermal energy is added, particles move _faster___ and _______farther apart__________.
23. When thermal energy is taken away, particles move ___slower___ and ____closer together_____________
24. A change in state is a ___physical__________ change.
25. Making a solution is a ____physical________ change.
26. Rust is a _____chemical_____ change.
27. List four clues that signal a chemical change.
a. bubbles__________
b. change in color, state or temperature__
c. _____smell____________
28. A built-up electric charge is called _____static electricity________ .
29. Examples of conductors:
30. Examples of insulators:
31. Flipping a switch on __closes_____ a circuit.
32. Flipping a switch off __opens_______ a circuit.
33. The direction of a compass needle always points ___north________ .
34. What makes an electromagnet different from a bar magnet?
35. _electromagnet can be turned on and off and uses electricity
36. ___A bar magnet does not use electricity and can not be turned on or off
37. Circuit A is a ___series_____ circuit.
38. Circuit B is a ___parallel______ circuit.
39. List the three parts that every working circuit has
a. power source (battery)___
b. _wire (conductor)______
c. _something that uses electricity (light bulb)_______

45. List the three properties of matter.
a. ___size___________
b. ____shape______________
c. ___color__________________
46. An example of a chemical property is _ability to burn___
47. Chemical property can be observed: _when matter is changed into a new kind of matter
48. An example of a physical property is _color, size or shape____
49. Physical property can be observed: ___without changing matter into something new _____
50. When a puddle of water evaporates, does the water change into a new kind of matter? Why or Why not?
Changing form a liquid to a gas is a change in state. Changes of state are physical changes, so an evaporating
puddle does not form a new kind of matter.
51. Like charges __repel____.
52. Unlike charge _attract_______ .
53. List the three parts of an electromagnet.
a. Power source (battery)_____
b. Conductor (wire)
c. _An iron core wrapped with a conductor (bolt wrapped wire)
