"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

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

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 activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

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

This is an activity to do when there is a solar eclipse!

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

This is a classic exercise for visualizing the scale of the Solar System.

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

Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
