In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

Millions of organisms can live in and around a body of water.

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.

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 discover if carbon dioxide has an effect on temperature.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

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 explore rocketry and the principals of space flight.
