Day and Night

There's more to that glowing ball of light in sky than most children realize. From the overall structure of the solar system, to the changing of the seasons, these hands-on lessons open the eyes of young scientists to...

Get your classroom rocking with this four-lesson earth science unit. Through a series of shared reading activities and hands-on investigations, young geologists learn about the three types of rocks and the unique properties of each.

How do different parts of the world experience day and night? Introduce scholars to the concept of global citizenship while teaching about animal behavior with discussion of nocturnal and diurnal animals. Then, learners complete...

Expand your third graders' universe with a science activity about Earth's rotation. They read a short explanation about the direction of sunlight, then draw an arrow to indicate which way the sun is pointed at an illustration of the...

Inform your elementary scientists why we experience day and night. They are provided with facts and explanation as to why the day and night cycle occur, discuss what they've learned with a partner, and are then given the task of writing...

Where does the sun go at night? Don't worry, it's just facing the other side of the earth. Learn about Earth's axis, tilt, rotation, revolution, and what all this means for your summer vacation with an engaging earth science video.

Why can't we dig through to the other side of the Earth? There are many layers and lots of heat, so the job is impossible. Watch a video that describes and explains each layer of the Earth.

The deeper you go into the Earth, the hotter it's going to get. Discover what is actually beyond the Earth's crust and why it gets hotter and hotter the further you go.

A lamp, four globes, and some signs taped around the room are all you need to set up a solar system simulation for teaching how Earth's tilted axis creates the seasons. (Sticky dots are also needed, but not mentioned in the materials...

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...
