Learners read an online article about an earthquake and follow up with a series of discussion questions about earthquakes. They answer questions in their science journals about continental drift, plate tetonics, and their influence on...

Eighth graders describe how the Earth's position causes seasonal changes. In this astronomy lesson, 8th graders explain how solar radiation varies depending on the season. They create a collage or poster on each of the Earth's four seasons.

Learners experience a computer based applet that explains why the Earth experiences tides.

Students discover how the position of the Sun, Moon and Earth affect tides. In this science lesson, students view a presentation about the tides. Students discuss the different types of tides.

Learners discover ways to preserve the Earth's resources. In this natural resources lesson, students investigate how many gallons of water the average American uses per day and then total their estimated usage. Learners discuss the...

Young scholars define soil, dirt, clay, silt, and sand. They conduct an online scavenger hunt, answer pre-written online questions on a piece of paper, and play the Earth Materials Game after completing the scavenger hunt.

Scholars collect data from heating sand and water before forming testable hypotheses about why sand heats up faster. Afterward, they develop and run experiments to test their hypotheses.

Where does all the heat go when the sun goes down? An interesting lesson has learners explore this question by monitoring the infrared radiation emitted over time. They learn that hot spots cool more quickly that cooler spots.

Here's a stat for your pupils: 18 percent of the human body is carbon! Part 10 in the series of 12 takes pairs on an adventure through the carbon cycle. After a class reading about carbon, pairs read and choose their own adventure...
