Varve: a deposit of cyclical sediments that help scientists determine historical climates. Individuals analyze the topography of a region and then study varve datasets from the same area. Using this information, they determine the...

Ninety-seven percent of scientists who study climate agree that human activity is warming the planet. Learners explore carbon dioxide as a greenhouse gas, a gas causing this warming, through a hands-on experiment. Once complete, they...

Brainstorm ideas to design a sustainable guest village in the Sonoran Desert. The first installment of a nine-part unit teaches young environmental scientists about the basics of the Saguaro National Park and about sustainable design....

You've heard of it raining cats and dogs ... but what about fish and frogs? It turns out, one scenario is much more likely than the other! Intrepid weather investigators examine the curious behavior of waterspouts using a leaf blower,...

It's cloudy with a good chance of learning! An inquiry-based lesson begins with an exploration of transparent, translucent, and opaque materials. Young scientists then connect their learning to the different cloud types as they take the...

Show the six-minute video, "Changing Planet: Fading Corals," and then demonstrate how calcium carbonate forms a precipitate in the presence of carbon dioxide. Separate your scientists into small groups to gather information about coral...

After viewing information about different types of isolation, students will see that reproduction among a group will cause the frequency of a specific trait to increase. The history of prominent scientists such as Charles Darwin are and...

For as small as they are, there sure is a lot of information for young scientists to learn about bacteria. Help simplify the subject with this instructional presentation that explores the structure, nutrition, and reproduction of...

Do you think you know better? Become a scientist and prove it. Scholars review the evidence for two different theories of the origins of the universe. They notice the empirical observations as well as the inferences to determine which is...

Pupils discuss the similarities between the Earth's atmosphere and a greenhouse. In this science lesson, students make their own greenhouses out of plastic bottles and thermometers. Pupils record the temperature different times of the...

Students study about natural resources and the decreasing amount. They observe the need for trained scientists and engineers. Finally, they take a small test to determine the areas of science they find most interesting.

Third graders investigate how scientists collect weather data in order to forecast the weather. They work in small groups in order to research one type of weather technology such as, satellite images, radar, surface observations, or...

Students create their own timeline. In this social science lesson, students write the important events that happened in their lives on their timeline and then compare their timeline to Earth's timeline.

Students create a PowerPoint presentation on the information they research about the ice cores and what they tell us about Earth's past. In this ice core lesson plan, students research radioactivity, air pollution, sodium, snowfall...

Students explore the formation of volcanoes. In this earth science lesson, students build their own volcanoes in the lab using different materials. They identify the different types of volcanoes.

Students download NASA Hubble Space Telescope images of the Martian polar ice caps in summer and winter, and measure and compare various images of the changing Martian and Earth polar ice caps.

Sixth graders research the average temperatures of different places on Earth. In this earth science lesson, 6th graders explain how the sun's heat cause ocean movement. They discuss how temperature change affects the weather we experience.

Second graders investigate the effect of melting glaciers to sea level. In this earth science lesson, 2nd graders simulate the process in the lab by conducting an experiment using ice cubes and clay. They explain the consequences of...

Students take part in a dice game to better explain the differences between direct and indirect evidence. They apply this knowledge to how scientists have used both types of evidence to determine how climate has changed over time.

Students determine the volume of water they displace. In this earth science lesson, students calculate the total water displaced by the world's population. They evaluate whether or not this value is enough to raise the sea level...

Second graders investigate daily weather changes. In this earth science activity, 2nd graders identify the different terms used to describe weather. They use the outdoor thermometer to record data.

Students explore the theory of Plate Tectonics. They participate in a simulation in which they re-enact the debate over Plate Tectonics vs. traditional beliefs of stationary continents that were widely accepted during the 1800's and...

Learners correlate surface radiation with mean surface temperature of several geographic regions. They observe how these parameters change with latitude and construct an understanding of the relationship of solar radiation to seasonal...

Students create their own environment. In this environmental protection lesson, students pretend they are the owners of a tropical island. They create jobs for the citizens and develop the island as a model environment.
