In this activity, learners use models of fossilized dinosaur teeth to understand how dinosaur teeth were used.

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

This activity (on page 2 of the PDF under SciGirls Activity: Extreme Sounds) is a full inquiry investigation into sound.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

In this math lesson, learners make estimates to analyze the number of apples per acre, and visualize the magnitude of one million.

In this activity, learners build a plastic emergence chamber (or use purchased "mini mosquito breeder") to observe and analyze the mosquito life cycle.

This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

This activity (on page 2 of the PDF under SciGirls Activity: Hockey) is a full inquiry investigation into how a hockey stick’s flex affects shooting power and accuracy.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.
