1. All objects and substances have physical properties that can be measured.
2.Measure the weight (spring scale) and mass (balances in grams or kilograms) of objects.
3. Measure volumes of liquids in milliliters and liters.
4.Matter exists in several different states: solids, liquids, and gases. Each state of matter has unique physical properties. Gases are easily compressed, but liquids and solids do not compress easily. Solids have their own particular shapes, but liquids and gases take the shape of the container.
5. Compare and contrast the states (solids, liquids, gases) of matter.

6. Changes in State- Matter can be changed from one state (liquid, solid, gas) to another and then back again. This may be caused by heating and cooling.
7. Explain how matter can change from one state (liquid, solid, gas) to another by heating and cooling.

All of these concepts are in their science notebooks.
