In this activity, learners investigate convection by using food coloring and water of different temperatures.

This chocolate chip cookie recipe includes templates for baking night sky constellations of the season right on top! Two templates are included, one for 9pm mid-April, and one for 10pm mid-July.

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 some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this activity, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

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

In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.

This activity features two connected hands-on activities about dinosaur bones.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

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

In this activity, learners create a sealed, mini ecosystem that supplies freshwater shrimp with food, oxygen, and waste processing for at least three months.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this activity, learners explore a bucket of sand and beach objects.

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?
