Endocrine Disruptors in Our Drinking Water: Should We Be Concerned?
Students investigate the different hormone contaminants in the water supply. In this math lesson, students analyze data tables and graphs. They demonstrate exponential growth and decay using frog populations.
Illustrative Mathematics
Logistic Growth Model, Abstract Version
Here learners get to flex some serious algebraic muscles through an investigation of logistic growth. The properties of the constant terms in the logistic growth formula are unraveled in a short but content-dense activity. Moving...
