Wheeeee! Young thrill seekers build a bungee jump—not for themselves, though, but for an egg. The egg must fall from a height of five feet and rebound within two inches of the ground or floor.

Students investigate the properties of plastic eggs filled with solids, liquids, and gases and use these observations to hypothesize whether a chicken egg is hard-boiled or raw.

Life on Earth is made possible by the unique composition of its atmosphere. Working collaboratively, a scale model is created as young scientists learn about the different layers of gas that surround the planet. Cards are included that...

Students investigate plate tectonics by observing a cracked egg shell.  In this Earth science activity, students draw borders of continents on an egg shell, only to watch it crack in a glass.  Students record the breakup of the...

Students discuss plate tectonics and the layers of the earth's interior. They use eggs as models of the earth and answer questions regarding which part of the egg would represent which part of the earth.

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...

Use the scientific method to experiment with an egg. Your class can examine buoyancy and density by finding how many spoons of salt are needed to float an egg. They can predict, experiment, record data, and analyze results.

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...

From days of 24 hour sunlight, to endless nights that last for days, the Arctic is a very unique place to live. Examine the seasonal changes that occur in the northern-most reaches of the globe and the impact they have on the plants and...

Paper mache projects are great for using up paper from the recycle bin. Give your class the chance to create a three-dimensional globe out of paper mache. They'll work to make their globes as accurate as possible, adding proper colors...
