High schoolers investigate the different hormone contaminants in the water supply. In this math instructional activity, students analyze data tables and graphs. They demonstrate exponential growth and decay using frog populations.

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...

Young scholars explore the components of a watershed and the factors that affect it. They read a topographical map and use geometry to determine the area of a watershed. Students estimate the volume of a body of water and perform runoff...
