COURSE DESCRIPTION:

Chemistry will give the student a better understanding of what matter is made of and how different types of matter react with other types of matter. Students will look at matter from a quantitative and a qualitative perspective.

COURSE BENCHMARKS:

1. Apply the vocabulary of chemistry

2. Use symbols to construct reactants, of predict products of, and balance chemical reactions.

3. Evaluate chemical reactions in a quantitative form.

4. Construct models of atoms and molecules.

5. Predict properties of atoms and molecules based upon their molecular structure.

6. Determine the quantitative affects of changing environmental conditions on the characteristics of gases.
