In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

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

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.

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 construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

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 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.

In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.

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

In this activity, learners explore the different heating properties of soil and water.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

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

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

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

This activity shows how our experience of the Sun changes with time and location. The sun dagger at Chaco Canyon is thought by many to be a sort of ancient timekeeping device.
