In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

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

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

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

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

This hands-on astronomy activity lets learners hunt for different objects in the night sky that contribute to stellar and planetary formation, using a Treasure List.

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

Make impact craters with marbles (or rocks or washers) in a container of flour. Find out what you can learn about your "comets" by the craters they make.

In this activity, learners use an astrolabe to measure the altitude of objects. Learners will first practice taking measurements by measuring the altitude of trees and buildings.

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

In this activity, learners explore the physics of impact craters from their own backyard using mud. Learners are encouraged to match features of real impact craters to their models.

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.

In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

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

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this craft activity, learners create a string of cut-out moons and stars.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.
