**Title:** What's Wrong With Global Climate Change? I Like it Warm!

**Description:**
Students will identify factors that affect the solubility of a salt and test one of the factors (temperature). They will apply their experience to ocean salinity, the effects of temperature on the composition of ocean water, and what effects that could have.
**Standard(s): **

[S1] CHE (9-12) 5: Use the kinetic theory to explain states of matter, phase changes, solubility, and chemical reactions.

**Title:** Exponential Growth and Decay

**Description:**
This lesson on exponential growth and decay involves a variety of teaching resources. There are a variety of websites used to teach and reinforce how to identify exponential growth or decay and how to solve problems relating to growth and decay. There is a lab provided that will help model these concepts being taught and computer based practice on these concepts. Videos are provided that give a picture image of how exponential growth and decay works. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
