Physical Change- change to matter in which no new kind of matter is formed
- Examples:
- Origami (art of folding paper)
- Cutting Paper
- Ice Melting
- Mixture- a substance that contains two or more different types of matter
- These types of matter CAN BE SEPARATED!! That is very important!
- Examples:
- Alphabet Soup
- Trail Mix
- Marbles and Beads in a bag
- Solution- a mixture in which the particles of the different kinds of matter mix together evenly.
- This is different from a regular mixture because you CANNOT SEPARATE the different kinds of matter BY HAND!!
- Examples:
- Salt Water
- Sweet Tea
- A Penny (this is a solution of two metals called an alloy. A penny is made of zinc and copper)
Chemical Change- change that forms a different kind of matter
- Examples:
- Cooking Food
- Rusting Nails
- Burning Wood
- What are some ways we use chemical changes in our lives?
- Burn fuel to power our cars.
- Cook food so we can eat it.
- Digestion
- FUN FACT: Plants use chemical changes to make their food!
