### Exponential Growth and Decay ...

We put the exponent in exponential growth! Learn the intuition behind the **exponential growth equation**, and **how to apply it**. Even get fancy with** negative growth. **Explore a range of problems involving exponential growth -- everything from **drug dosing to windmills to human population**. By the time we're done, you'll wonder how you ever survived without it!

### The Mystery of the Missing Housefly

Did you know that a single housefly can produce almost 2 million offspring in a month? And that's just the female babies. So **why aren't we knee-deep in houseflies?** And** what does carrying capacity, logistic growth, or disturbance** have to do with it? You be the detective....

### Bacterial Dynamics: *E coli* ate my homework

Our ultimate quarry: the E. coli that devoured the lab report ... metaphorically speaking. Find out **why a tiny amount of contamination produces an overwhelming disaster**. along the way, we'll zip through the **exponential growth equation**, calculate **doubling times**, **"unbend" exponential growth** on a log plot, learn to deal with **messy numbers**, and even approach the great and mysterious constant named **"e"** in search of a better way of comparing growth rates. Eww, careful with that yogurt!

### Mutation and Equilibrium....

Develops the Hardy-Weinberg phenotypic probabilities from an intuitive/probabilistic point of view. Demonstrates the use of chi-square to test for Hardy-Weinberg outcomes. Explores the graph of the Hardy-Weinberg outcome. Compares Hardy-Weinberg equilibrium with equilibrium obtained from mutation. Discusses iteration of the mutation equation.
