Matter
This physical property tells us if the matter dissolves in water.
Solubility
Physical or chemical Change:
formation of a gas
Chemical
The sum or the materials in a mixture is the same OR different then the mass of the original materials.
Mass is the same as the original materials.
Heterogeneous or Homogeneous Mixture?
Cereal and Milk
Heterogeneous
This state of matter has no fixed shape and no fixed volume.
Gas
This physical property refers to the way light reflect or bounces off an object.
Reflectivity
Why does fruit change color as they ripen?
Chemical changes from the air, temperature, and light. (I will accept any one of the three chemical causing changes.)
Mass is the measure of what?
the amount of matter in an object
Koolaid and Water
Solution or suspension
Solution
This type of matter has a definite shape and takes up a definite amount of space.
Solid
This physical property describes how electricity or heat moves through a material.
Conductivity
True or False. Bubbles in a soda are a chemical change.
False

Physical
Which has more mass, an inflated balloon or a bag of marbles?
Bag of marbles.
Explain colloid.
A heterogeneous mixture in which the parts are so small they do not settle out.
True or false. The shape of sometimes up matter can be changed more easily than others.
True
Some matter has chemical properties that causes them to react with air or heat. Name one material that reacts with air or heat.
Banana
Wood
Metals
How do we identify a chemical change?
A new type of matter is formed.
(Different)
Adding salt to water will change the mass of the water in what way? Increase or decrease?
