In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

Learners demonstrate how water can distort, refract and magnify light.

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 outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

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 quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation about the different causes of glacial melt.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this activity, learners investigate passive solar building design with a focus solely on heating.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.
