4. Mixtures and Physical Properties
Yesterday, we reviewed that some mixtures retain their physical properties when mixed like iron filings and sand.
What if we mixed salt and water? Would the salt and water retain their physical properties? How would they change?

5. Mixtures and Physical Properties
Look at the two items being mixed.
Describe the difference in physical properties in each example before and after mixing.

6. Changes in States of Matter
Changes in the state of matter can occur when a substance is cooled or heated.
What changes will occur when water is cooled to 0˚C?
What changes will occur when water is heated to 100˚C?

7. Changes in States of Matter
Describe the change in the state of matter that will occur in these examples:
+ HEAT
+ HEAT
+ COOLING
+ COOLING
