1. Matter: Properties and Change

2. Matter
Anything that takes up space and has mass

3. Law of Conservation of Matter
Matter can not be created or destroyed
These legos weigh the same when they are together and taken apart

4. qualitative Information collected and communicated in words
Observable by using your senses
Example: color, shape, odor

5. quantitative
Exact information about the quality you observe using numbers rather than words.
Example: length, weight, volume, temperature

7. weight
Measure of the pull of gravity on an object

8. States of Matter Solid-definite volume; doesn’t change
Liquid-a definite volume but no shape
Gas- no definite volume or shape
Plasma

10. Boiling Point – The temperature at which liquid matter experiences the same pressure as the atmospheric pressure; turns to a gas
Freezing Point – The temperature at which liquid matter turns to solid.

11. Melting Point – The temperature at which solid matter turns to liquid.

12. Physical Properties of Matter
Observable characteristics that can change without changing their chemical composition
Example: color, form or shape

13. Physical Change
Changes in shape, size or physical state (phase) of matter
Example: Shredding paper, cutting up fruit, freezing water, boiling water

14. Chemical Properties of Matter
Properties of a substance that when changed, result in a new substance
Example: ability to conduct heat; reactivity with other substances (rust)
These properties create chemical changes in a substance

15. Chemical Change A change in matter that produces new substances
Examples:
Ability to burn
Wood to ash
Ability to rust/ react with oxygen
Metal to rust
Ability to form a new substance with chemical composition different than the original substance.
Digestion of food
