Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.

In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this activity, learners make a photographic image—without a camera!

In this hands-on activity, learners investigate the functional design of leaves on a tree.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

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

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

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 activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.
