-Physical

-Boiling Point

-Melting Point

-Density

3. Explain how elements can be identified, You can see the differences in the different elements. The different densities and the different colors and shape of the elements.

4.    Classify elements according to there properties,   They have to share enough properties to be classified in the same group.

5.          How elements make compounds,    When 2 elements combine undergoing chemical change.

6.        How can a compound be broken into a element?  Some compounds can be broken down by chemical changes. Other compounds are broken down by other chemical changes.

7. Explain how a compound can be broken down into its elements?,      Some compounds can be broken down by chemical changes. Other compounds are broken down by other chemical changes.

8. Give examples of common compounds,   Food that you consume, School supplies that is being used, Clothing that is being worn and You are a compound
