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

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, learners shrink the scale of the vast solar system to the size of their neighborhood.

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

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

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

Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

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

This is a classic exercise for visualizing the scale of the Solar System.

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.

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

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

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

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

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

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 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 will investigate the impacts of harmful phytoplankton using NOAA's Coastal Services Center Harmful Algal Bloom Forecasting (HABF) Project data.
