spit labMacromolecules and Environmental Effects on Enzymes

by Jenn Yost and Erin Mejía

In this module students will do an activity and a lab. A cut-out activity illustrates the anabolic and catabolic functions of enzymes, enzyme specificity, and the individual components of macromolecules. Students then test the effects of temperature on enzymatic activity in spit.

Vanishing Shells

vanishing shellsEffects of Ocean Acidification on Marine Life

by Tara Cornelisse and Bill Callahan

This project is an opportunity for students to learn how increased carbon dioxide in the atmosphere decreases the ocean’s pH and negatively affects shelled marine organisms. Students start with short informational videos and news readings, and then a real-life problem (an oyster business) as the context for designing questions, hypotheses, and investigating this phenomenon through hands-on experiments.
