Physical Science

4. Water that falls to the earth as hail, mist, rain, sleet, or snow.
6. Matter that has a definite volume and a definite shape.
8. A material that transmits heat.
10. The amount of space found in objects.
12. A substance that has no definite volume or shape.
15. Transfer of energy by electromagnetic waves through space.
18. This is when there is no change in matter.
19. This is when a new matter or substance has been formed.
22. When a substance shrinks in size.
24. A process by which a substance changes from a gas state to a liquid state.
26. The measurement of how fast an object is going.
27. Characteristics and qualities that describe matter.
28. The process by which plants give off water vapor through openings in their leaves.
29. A material that is a poor conductor of heat.
31. A substance that reduces friction

1. A push or pull that changes the motion or position of objects.
2. Has a definite volume and takes the shape of its container.
3. A force that pulls objects towards the center of the earth without direct contact.
5. Transfer of thermal energy between two objects that are touching.
7. This is when an unbalanced force causes a change in the motion of an object.
9. The process of changing from a liquid to a vapor.
11. This is a result of a gravitational pull on objects.
13. A speed or type of rhythm or movement.
14. A force that stops or slows down an object.
16. The space between two points.
17. This is the amount of matter in an object.
20. When a substance grows in size.
21. This is the amount of matter in an object.
23. Everything that takes up space.
24. Movement of thermal energy by the movement of liquids or gasses.
25. Everything that takes up space.
30. Occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into creeks, streams, or ponds.
