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

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 conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

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 activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

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 chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

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 quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

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 grow sugar crystals (rock candy). They make a hot solution that has an excess of sugar dissolved in it, then as the solution cools, they see sugar crystals form.

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

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

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 activity, learners build models of comets, using edible materials, to learn about comets' structure.
