In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

Can gelatin (like Jell-O ®) change the speed of light?

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?

In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

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