In this lab, students will work with a simple algae/brine shrimp environment to learn about food chains and population dynamics.

I've been working on this activity over the past few days. If your brine shrimp aren't growing as fast as you want or not as big as you want, set up a population in a beaker/jar/flask and add some algae in with the young brine shrimp/ Once they get a good diet of algae available, they will start to grow rapidly.

Here are links to videos students can watch prior to lab to understand the procedure better.

I've added spreadsheets that we used for calculating algae concentration from the absorbance readings, t-test, and ANOVA. There are tools in Excel to do the tests, but these spreadsheets are simpler to understand and a bit more forgiving.
