This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity, learners model the gravitational fields of planets on a flexible surface.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.
