1. Whats the difference between an atom and a molecule?A.An atom consists of a nucleus (containing one or more protons and zero or more neutrons) and some number of electrons. Atoms have the same number of protons and electrons, because otherwise, you would have an ion.
A molecule consists of two or more atoms bonded together.

2. Work with any of the Chemistry Simulations to create your own Teaching Idea. The criteria for this is as follows:
a. must identify and meet three (3) science education standards
b. must be original work
c. must be scientifically accurate and appropriate for the directed grade level.

A.4.2 When faced with a science-related problem, decide what evidence, models, or explantations previously studied can be used to better understand what is happening now
C.4.6 Communicate the results of thier investigations in ways their audiences will understand by using charts, graphs, drawings, written descriptions, and various other means, to display their answer
G.12.2 Design, build, evaluate, and revise models and explanations related to the earth and space, life and environmental, and physical sciences
