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

This activity (on page 2 of the PDF under SciGirls Activity: Music and Sound) is a full inquiry investigation into sound frequency.

In this activity, learners create a three-dimensional sculpture while examining the characteristics of fish.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

Learners take on the role of environmental engineers as they design water filters.

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

In this activity, 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.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this activity, learners create their own archaeological profiles.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

In this hands-on art activity, learners will study and identify features of the external anatomy of a fish.
