This activity focuses on interactions within Earth systems and the effects of human activities. In this activity learners build a biomass pyramid.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

This activity helps the learner answer the question: "What environmental problems arise due to animal and human overpopulation and what might need to be done to combat these problems?" Learners play a

This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.
