3. Getting Started
You need a copy of Student Sheet 12, or to keep track of all the information on notebook paper in an organized fashion.
We’ll look at three substances that are added to water and practice writing about them.

4. Food Coloring and Water
Describe the properties of this mixture.

10. Lab Students had 5 jars with pure substances:
Copper (II) sulfate (CuSO4)
Sodium chloride (NaCl)
Zinc Oxide (ZnO)
Sulfur (S8)
Sodium Nitrate (NaNO3)
1 lab scoop of each substance was put in a test tube, and then water was added to the test tube.
Test tube was shaken for at least 10 shakes. Then students made observations and wrote about the appearance and whether the material dissolved.

11. Copper (II) Sulfate Describe this mixture.
Determine if the substance dissolved.

12. Sodium chloride Describe this mixture.
Determine if the substance dissolved.

13. Zinc Oxide Describe this mixture.
Determine if the substance dissolved.

14. Sulfur
Describe this mixture.
Determine if the substance dissolved.

15. Sodium nitrate Describe this mixture.
Determine if the substance dissolved.
