Students analyze water samples to see the contaminants and then use the Internet to find the sources of the contamination.  In this investigative water activity students analyze water and work together to solve the mystery of...

Students watch the teacher make a cloud. In this water cycle lesson, students discuss the water cycle and see the formation of a cloud. The teacher leads the discussion including the role of water vapor, smoke and air pressure.

Students elicit data on the water cycle, ocean topography, and island formation in this six lesson unit. The ocean floor and the properties of water are examined through a variety of discussions and hands-on experiments.

In this science worksheet, students look for the meaning of the water cycle and its relation to the formation of clouds. They read the information about the different types of clouds.

Middle or high school environmental studies classes will learn much from this presentation on energy in ecosystems. It covers the foundational topics of trophic levels, food webs, and nutrient cycles using informational text and...

A critical look into the structure and function of ecosystems is here for young learners as a series of lessons and worksheet activities. Topics covered include land-based and marine ecosystems, connections to the water cycle, food...

Thirsty plants soak up every bit of a rainfall, but what happens to the rain that hits the roof? Calculate the amount of rainwater from your school's roof with an Earth science activity, which brings measurement skills, observation...

The thaw depth of tundra creates a positive feedback loop with both global warming and the carbon cycle. Scholars sort photos and develop a hypothesis for ground cover and permafrost depth. Then they review the data and measurements...

Students examine their connection to local watersheds. They describe the water cycle and list species living in their local watershed. They also draw a map of their community.

AP biologists or college-level botanists consider in-depth details of the photosynthetic process. They examine the structures in a leaf and the roles that they play. They label neat and colorful diagrams of photosystems and electron...

Biology classes will bubble with excitement as they complete this assignment. Beginning with an informative overview of cellular respiration and fermentation processes, the highlight comes as an experiment in determining the rate of...

Future meteorologists play a Jeopardy game to review vocabulary and concepts taught during a weather unit. Questions cover such topics as weather vocabulary, tornado safety, the water cycle, and cloud types are part of this review.

Young scholars explore the various steps of the water cycle. They identify the three steps in the water cycle and how they are related. Students describe three ways to conserve water. Young scholars explore the origin of the water...

Ninth graders investigate biological systems. They summarize relationships between systems. Students determine how systems relate within the biosphere. They analyze the carbon cycle.

Students explore the parts of the rock cycle and the process of erosion as they build their own mountain and observe the effects of wind and rain as erosive agents.

Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what...

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Dirt babies are an excellent way to show young botanists the plant life cycle. They explore the functions and industry behind grasses before growing some of their own. Use the informational text here and consider implementing some...

Educate scholars on pollution—air, water, and land—with a series of lessons that begin with a thorough explanation of each type. Learners then take part in three activities to reinforce the importance of reducing pollution. They...

Flotsam by David Wiesner and The Magic School Bus on the Ocean Floor by Joanna Cole, illustrated by Bruce Degen, begin a reading adventure pack focusing on oceans. With story listening and thoughtful discussion, scholars complete several...

Explore soil, genetic traits, natural resources, and pollution in a series of lessons that focus on biodiversity. Kids complete experiments to learn more about the importance of varied genes and organisms in an ecosystem.

This extensive earth science practice test comprises 50 multiple-choice questions and 31 short-answer questions. The questions cover weather, the water cycle, geology, the solar system, and more. Many of the short-answer questions refer...
