1. Problem of the Day
Jose puts water, sugar, and yeast into a balloon. He measured the mass and volume of the balloon. Then he put the balloon in a warm place. What will happen to the mass and volume of the balloon?
a. The mass and volume will change
b. The mass will stay the same and the volume will change
c. Nothing will happen.

2. I will be able to understand the difference between chemical and physical changes.

3. Classifying change
Matter has physical properties that can change how it looks but not what it is made of.

4. Classifying change
Matter has chemical properties that when it changes can cause it to have a new identity(different matter)
This happens when things
Burn
Get rotten
Things rust
A new substance (like gas) is made.

5. How water changes Water can not go through a chemical change.
It expands(gets bigger) when it is cold and contracts(gets smaller) when it is hot.

6. Temperature When matter gets hot it expands
When it gets cold it contracts.

7. Increasing Temperature
Increasing temperature causes chemical reactions to happen faster.
