In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.

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 explore how the power of the sun can be harnessed to heat and cool a building.

Like water drops in falling rain, a CD separates white light into all the colors that make it up.

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 lesson that includes hands-on activities and demonstrations, learners discover that it is the tilt of the Earth's axis (not its proximity to the sun) that causes the seasons.

In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

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

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

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

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.

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

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

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

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
