Plant Transpiration

Looking for a tree-rific addition to your water cycle unit? Teams of young foresters examine the role of transpiration in the water cycle through a week's worth of activities. Pupils analyze how trees take in and transport water during...

Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...

The four cycles in Earth's biogeochemical system are covered in this activity. Science stars fill in the blanks or define vocabulary terms pertaining to the hydrologic, carbon, nitrogen, and phosphorous cycles. This resource provides a...

What a packed lesson! Provide your class with the opportunity to learn about the cell cycle in several exciting ways. Biologists first learn about the theory behind mitosis, then proceed to view onion tips under the microscope and create...

A woman had a job crushing cans at the recycling plant; it was soda pressing. Video focuses on the ways our environment recycles, including the water cycle, carbon cycle, nitrogen cycle, and the phosphorus cycle. It also describes the...

How quickly does a plant transpire? Learners explore this question through measuring water uptake with a potometer. They time the movement of a bubble a set distance to understand the motion and rate of speed.

Water that leaves the oceans must eventually return. The animations in the final lesson of the four-part NASA series show the complex path water can take across landforms before returning to the ocean. Approximately one-third of the...

Go with the flow! The first video of a seven-part series about the Earth's water resources introduces learners to the water cycle. With an emphasis on cause and effect, it presents the information simply through animation. And, with the...

This is a good explanation of plant water balance issues and carbon fixing cycles. Transpiration processes are explained well with links to additional information.

A quick summary of the water cycle that includes a diagram of the cycle, with links to in-depth explanations of each component of the cycle. Click "water-cycle home" to access water-cycle resources in a variety of languages.
