How the nematode C. elegans maintains balance in a changing environment

This 5-lesson module was designed as an in-class laboratory experiment. A website using videos of worm behavior was developed for online learning. Both are available below.

The lessons teach how worms maintain homeostasis in a challenging environment, how genes and environment interact to determine traits, and how an environmental factor affects the expression of a trait (NGSS HS-LS1-3, HS-LS3.B). The unit also reinforces the concepts of transcription and translation.
