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

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 cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

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

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.

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

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

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

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

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

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

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

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.
