In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

In this multi-step experiment (page 4 of pdf), learners study tide pools, and then drop a "wave" (a 4-pound bag of beans or birdseed) on a shell to mimic the force of crashing surf on tide pool animal

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

In this activity related to dinosaurs, learners explore why animals live in families. Learners discuss and identify animals living in families or groups from images and photos.

In this family or group activity, learners conduct a chromatography experiment to reveal the colors that leaves "hide" under their green pigments.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.

Learners develop an understanding of air pressure in two different activities.

Learners build devices from rubber bands to test for invisible air pollutants.

In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.

Learners gain an intuitive knowledge of the physical aspects of watersheds by creating their own watershed models.

This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.

Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.
