Why do rocks break down over time? Learners explore this concept by simulating physical and chemical weathering of different types of rocks. They use an abrasive to demonstrate physical weathering and acid to demonstrate chemical...

The earth has a love-hate relationship with carbon. Learners complete a series of nine lessons that begin with an examination of the role of carbon in Earth's systems. They then relate changes in climate and weather to changes in the...

After learning about P waves and S waves, fifth graders view the intensity of earthquakes by examining seismographs and images of earthquake damage. Young scientists then forecasting future quakes by analyzing data about...

Kepler's second law of planetary motion, specifically, the law of equal areas, is demonstrated by your high schoolers. On the provided graph paper, they mark out the designated path of Earth at two different times of the year and then...

A whole-group discussion kicks off a hands-on activity that challenges young engineers to build a sailboat using reusable materials. Participants gather recycled items to assemble their one-of-a-kind sailboat and test its ability to...

Students use topographic map skills to interpret impact of the May 18, 1980 eruption of Mount St. Helens on the volcano's topography, and draw profile views of Mount St. Helens before and after the May 18, 1980, eruption.

Having a clean, reliable source of drinking water is essential for any community, but in many cases this is easier said than done. Engage young environmentalists in exploring the five factors affecting vulnerability of a groundwater...

Welcome to your new job as an astrophysicist, astrobiologist, engineer, or research scientist at NASA. Your job is to search for alien life in our solar system! Throughout a unit of activities, learners search the galaxy through...

Eighth graders explore the characteristics of responsibility. In this character lesson, 8th graders complete a self-evaluation. Students view a responsibility video. Students write a newspaper article on selected environmental issue.

How has human activity affected Earth's watersheds? An action-packed lesson plan, part of the K20 Center, examines water's ability to go with the flow regardless of what is in its path. Scholars build model watersheds, examine time-lapse...

Earth didn't always have oxygen, so what caused the change that allows humans to live here? Learn about the change in O2 levels throughout geological history through an interactive graph. Each section offers greater detail on the changes...

Learners are introduced to Gaia theory of natural homeostasis. They graph Earth's temperatures over time, construct terrariums or monitor the outdoor environment. Related videos titles are suggested, but may be outdated. The objectives...

A few of the components of this lesson are not possible to carry out because the rock cycle diagram and challenge handouts are not included. Hopefully, you already have your own rock cycle diagram or worksheet to use as a concept...

In this space science worksheet, students find the answers to the questions concerning the topic of the sun and they label the diagram for the sun.

Students identify the different layers of the Earth. In this earth science lesson, students create a model of the crusts and continents. They explain how plates movement cause earthquakes and volcanoes.

Students organize rock samples according to their properties. In this earth science lesson, students predict whether they are igneous, metamorphic or sedimentary. They compare their prediction with the actual type.

Fourth graders research sources of fossil fuels especially oil while determining how scientists take core samples from an Earth model. They look at oil consumption and production in the US and throughout the world.

Students investigate the earth's structural layers by participating in hands-on activities. They identify the earth's structure and investigate earthquakes.

Students compare and contrast the characteristics of Earth and Saturn. They practice writing analogies using those characteristics. They complete a worksheet to end the activity.

Students complete activities to learn how to use Google Earth and study Alaska. In this Google Earth lesson, students complete a Google Earth scavenger hunt to find facts about Alaska. Students complete two worksheets for the topic.

Students examine the tilt in the Earth's revolution around the sun. Using that information, they draw a picture and label the indirect and direct rays of the sun. In groups, they answer discussion questions and complete an assessment...

Students simulate the Earth's revolution around the sun using CEENBoT. In this earth science lesson students calculate the Earth's distance in AU and it's speed of revolution. They explain how the Earth's movement cause seasonal variation.

Students use the Internet to investigate earthquakes and plate tectonics. In this plate tectonics lesson, students complete a web quest with multiple links and activity types relating to earthquakes and volcanoes. They connect the...

Students complete activities to become more aware of environmental issues and the effect on plants and animals. In this environmental issues lesson, students use a globe to discuss issues with the environment. Students then take a trip...
