In this food chains worksheet, students complete a crossword puzzle by placing 16 terms into the puzzle that match the clues given. Students review food webs, biomass pyramids, and the water cycle.

Students explore the cycles of an ecosystem.  In this environmental science instructional activity, students work in groups to research the nitrogen cycle, the water cycle, or the oxygen-carbon dioxide cycle. Students prepare a...

Fifth graders observe how water changes phase through a teacher-led demo. In this earth science instructional activity, 5th graders relate the demo to the water cycle. They draw and label each stage of the cycle.

Students investigate the water cycle using activities from The Magic School Bus series. They determine what happens when water is heated and cooled by observing two different experimental set-ups.

Eighth graders study the effects of the water cycle. They create a graph of the air temperature versus solar radiation on a rainy and clear 24 hour period using data from a provided link. Afterward, they answer questions to determine the...

Knowing about the hydrologic cycle is the first step to understanding the carbon cycle. Upper graders discuss the earth's water content, polar ice caps, and the concept of the ecological cycle as it applies to carbon, nitrogen, and other...

Here's a powerful demonstration that makes the point that it is everyone's responsibility to conserve water and protect the earth's limited supply of fresh water.

Students explore the water cycle. In this water cycle lesson, students complete a hands-on activity that replicates the water cycle. Students record their observations.

Students explore the water cycle and the path a single drop of water would take if it traveled from their schoolyard to the Chesapeake Bay in Virginia.

Students identify the ways in which water moves through our environment and consider the different forms it can be found in. They view videos, conduct experiments and participate in class discussions. Students determine the role that...

Eighth graders are introduced to the Earth's hydrologic system including the cycling of water in the atmosphere and the movement of water on the surface of the planet using the Great Lakes watershed as an example.

Students observe and identify the stages of the water cycle by observing a simulated water cycle. They complete worksheets demonstrating their knowledge.

Focused little scientists will flitter their arms back and forth across the room with excitement as they learn the life cycle of a butterfly and how living things grow and change over time.

Throughout this earth science exam, high-school geologists complete a series of multiple choice and short answer questions about the solar system, atmosphere, and earth system. This is an amazing test, as are all of the exams developed...

Students build a model and observe the cycle of evaporation and condensation that occurs in the water cycle. They see how the water cycle works, such as water condensing on the side of the jar and drops precipitating into rain that...

Part three in the series of seven has pupils discussing the different greenhouses gases, learning about the carbon cycle, and then watching a short video about the carbon cycle. Based on their knowledge, individuals complete a greenhouse...

Students discover the different forms of water on Earth. In this states of water lesson, students read material on the different forms of water and how they are created. The students answer written questions on worksheets.

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

Explore the Earth's different ecosystems through four lessons, an assessment, and extension activities. Lessons include informative text and step-by-step instructions to apply knowledge in interactive, and thought provoking ways; such as...

Students learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students work in small groups to find out if foods they eat contain water.

Students compare quantities of water. In this water lesson students examine the hydrologic cycle looking for the amount of fresh water that is available. Students use information from charts and diagrams.

Students become familiar with the water cycle and water issues.  In this water lesson students examine what they can do to protect their water.

Students discuss flooding and its causes. They view a Powerpoint presentation about floods and prevention methods. After creating a model with clay and pans, they investigate river behavior in various terrains with different amounts of...

Third graders observe the properties of water and in its different states. In this states of matter lesson, 3rd graders view a video, read The Magic School Bus at the Waterworks and experiment with freezing, melting and boiling...
