Standard 3: Physical

Resources

Benchmark

Indicator

A.   Explain how variations in the arrangement and motion of atoms and molecules from the basis of a variety of biological, chemical and physical phenomena.

1.   Explain that elements with the same number of protons may or may not have the same mass and those with different masses (different numbers of neutrons) are called isotopes. Some of these are radioactive.

2.   Explain that humans have used unique bonding of carbon atoms to make a variety of molecules (e.g., plastics).

 

B.   Recognize that some atomic nuclei are unstable and will spontaneously break down.

N/A

 

C.   Describe how atoms and molecules can gain or lose energy only in discrete amounts.

3.   Describe real world examples showing that all energy       transformations tend toward disorganized states (e.g.,       fossil fuel combustion, food pyramids and electrical use).

D.   Apply principles of forces and motion to mathematically analyze, describe and predict the net effects on objects or systems.

4.   Describe real world examples showing that all energy transformations tend toward disorganized states (e.g., fossil fuel combustion, food pyramids, and electrical use.

5.   Explain how electric motors and generators work (e.g., relate that electricity and magnetism are two aspects of a single electromagnetic force). Investigate that electric charges in motion produce magnetic fields and a changing magnetic field creates an electric field.

 

G.   Explain the properties of gases.

5.   Apply Avogadro’s, Boyle’s, Charles’ and the Ideal gas laws.

6.   Understand pressure and how it is measured.

7.   Describe the behavior of gases in terms of the Kinetic Theory.

 

H.   Demonstrate the quantitative nature of chemical reactions.

8.   Use the mole in molar mass calculation.

9.   Calculate percent composition, empirical formulas for a compound.

10.  Solve stoichiometry problems.

11.  Balance a chemical reaction using the conservation of matter.
