The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

How many times have you traveled around the sun? Aspiring astronomers grasp what a year is and they differentiate between orbit and rotation by walking around the sun right within your classroom. Place a lamp in the center of the room to...

Who needs a compass to find cardinal directions? Just place a stick in the ground and record the movement of its shadow over the course of a day. Then, measure the shadow lengths in order to determine a north-south line. A simple...

If you feel like you're standing still, you're wrong! The Earth is constantly rotating and orbiting under our feet. Demonstrate the Earth's movement within the solar system with a collaborative activity. With a candle or lamp in the...

Learners investigate how solar energy is converted into heat in part two of the 10-part Discover Your Changing World series. They build and test homemade solar cookers to boil water and cook rice. Pupils consider the impact of heat...

Sundials are more than just primitive clocks. Learners build their own sundials to study the location of the sun across the sky throughout the day. They use shadow evidence related to their sundials to make conclusions about solar movement.

Three activities make up a solar system lesson that features the sun, its light, and the shadows it produces. Scholars step outside to discover the changes shadows make at different times of day, take part in a demonstration of...

Take young scientists on a trip through the water cycle with this interactive science activity. After setting up a series of ten stations representing the different places water can be found, children use the included printable dice...

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

How is solar energy able to move wind and water to control the climate? Scholars explore the concept of solar energy in the first of 10 activities in the Discover Your Changing World series. They follow instructions to build homemade...

After completing the activity, "Kinesthetic Astronomy: The Meaning of a Year," zoom in on Earth's rotation using the same simulation setup and this outline. Each class member dons a map of the Western Hemisphere and plays the part of...

Calculate the movement and properties of planets like professional astronomers! Scholars use Kepler's third law to find Mercury and Venus's distance from the sun. Using changes in brightness of distant stars and Kepler's third law,...

Scholars examine, cut, paste, and sort 12 images featuring different types of movement in order to show what they know about energy—potential and kinetic. 

How do satellites communicate? What types of satellites orbit Earth? Discover and mimic the way satellites communicate between two points in a hands-on activity that has pupils using mirrors, flashlights, and marbles.

In this science fair project, design and build a mechanical sunflower device that faces the Sun as the sun moves through the sky. By harnessing solar energy, your sun tracker should follow the movement of the sun.

This fun activity helps you to understand the movement of the sun by studying shadows.

Learn how to use the sun to tell time. This simple activity reinforces the concepts of light and shadow, night and day, time, and geographical north vs. magnetic north.
