Learners explore the basics of ecology. They discuss ecological succession, the water cycle and human impacts on the environment. Students explore the owls, succession, the human impact on the environment and complete the "Incredible...

Students conduct various experiments to investigate plant transpiration. In this biology lesson, students explain how this process helps maintain the hydrologic cycle. They measure the rate of water loss in plants using a potometer.

Students construct their own diagrams outlining the pathway of carbon and oxygen in our atmosphere. They listen to a lecture on the carbon cycle while drawing an example of the carbon cycle on the board. Students comprehend that CO2 is...

In this carbon cycle lesson, middle schoolers review the carbon cycle and visit stations in the room where they experience every phase in the carbon cycle. Students journal about their journey through the cycle and brainstorm ways...

Young scholars complete an experiment. In this precipitation lesson, students complete an activity where they make rain in a jar.

Students examine the changes as water goes from solid to liquid. In this states of matter lesson, students observe and record the changes to water as it changes from solid to liquid and back to solid.

Students study drinking water. In this environment lesson, students draw the path of drinking water from the place of precipitation to the tap after researching a map and information from the United States Geological Survey water...

Pupils discuss how groundwater becomes polluted. In groups, they design and create models of groundwater pollution sources. They demonstrate to the class how the water may become contaminated from local and nonlocal pollution sources.

Learners are introduced to rainfall measurement and develop a network of rain gauges. Students measure rainfall, plot rainfall maps and calculate total rainfall volumes during rainstorms.

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.

Second graders work in small groups with a cup each of several materials. Students layer the gravel, sand, and water into a resealable bag. They draw a picture of this bag in their water journal. Students place their sealed bags in a...

Students illustrate how water is stored and the water cycle. They discover how underground water can become contaminated.

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.

This weather PowerPoint features a game in which students advance to the finish line with a race car as they answer questions related to weather. Topics include types of clouds, weather instruments, the water cycle, and various weather...

In this surface water activity, students review water runoff, drainage basins, and river erosion. This activity has 7 multiple choice and 3 fill in the blank questions.

Students identify and describe various organisms living in a pond water environment. They describe the characteristics of living things. Students compare and contrast organisms created by asexual reproduction and sexual reproduction....

Student learns about the life cycle of plants by watching a time-lapse video. This activity provides students with further evidence that all living things grow and change as they progress through their life cycle. Student conducts a...

Learners examine the rock cycle and the path that rocks go through to rearranged in different ways. They define key vocabulary terms, then in small groups conduct a variety of experiments using crayon shavings as simulated rocks and...

Students conduct hands-on experiments. In this life cycle lesson, students are able to observe a variety of animals as they travel through their life cycle (brine shrimp, mealworms, frog eggs and chicken eggs). Students respond to what...

Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...

High schoolers gather mosquito eggs to record the mosquito life cycle using drawings, descriptions, and any other appropriate means. In small groups, they analyze and describe the process of complete metamorphosis. They classify...

In this exploring the processes from seed to reproduction of a plant online interactive worksheet, students read a passage explaining the plant life cycle and answer multiple choice questions about what they read. Students choose 8 answers.

Learners discuss ammonia, and ways it may get into the aquarium. They complete a worksheet about the Nitrogen Cycle. Students learn how to get the ammonia and nitrite out of their aquarium.

In this life cycle worksheet, 9th graders complete 3 different procedures that distinguish viruses and bacteria and inherited characteristics. First, they read the background excerpt given about bacteria and viruses. Then, students cut...
