In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

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.

In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

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 (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

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

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

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

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.

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

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.

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 outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.
