Physical Science Standards:
1. Identify characteristics of a simple physical change
(e.g., heating or cooling can change water from one state to another and the change is reversible).
2. Identify characteristics of a simple chemical change.
When a new material is made by combining two or more
materials, it has chemical properties that are different from t
he original materials (e.g., burning paper, vinegar and baking soda).
3. Describe objects by the properties of the materials from which
they are made and that these properties can be used to separate or
sort a group of objects (e.g., paper, glass,
plastic and metal).
4. Explain that matter has different states (e.g., solid, liquid and gas)
and that each state has distinct physical
properties.
5. Compare ways the temperature of an object can be changed
(e.g., rubbing, heating and bending of metal).
