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...

Eighth graders investigate the water cycle and its processes. They examine temperature and precipiation data to classify climate of ten cities. They then create a climate map of the world.

Students investigate the water cycle and cloud formations by examining photographs.  In this weather lesson, students observe pictures of specific cloud types and identify them by putting them in groups.  Students describe the...

Students research the water cycle and identify main vocabulary associated with the water cycle. They build and observe a closed system model that demonstrates the water cycle in action.

Students create an "animated" water cycle wheel that illustrates where water comes from and where it goes.

Students take a virtual trip to a Catfish Aquaculture Pond and analyze soil bacteria to determine how many nitrogen cycle bacteria are present. They graph the number of colonies present and use data to determine ammonium levels in the soil.

Students explore hydrology concepts. In this environment and biology lesson, students identify and describe macroinvertebrates using a variety of pictures and resources. Students observe and write about a classroom aquarium in which...

Students investigate the lives of frogs by completing several worksheets.  In this biology lesson, students discover the life cycle of a frog from tadpole to death.  Students complete frog life cycle puzzle as well as create a...

This project provides students the opportunity to investigate parasites as a possible cause of the observed frog deformities. It asks students to view web-based evidence and interpret whether it supports the parasite hypothesis. Students...

Seventh graders identify how much carbon is held by the world's forests. For this forestry lesson, 7th graders study the carbon cycle and discuss what role humans have had on climate change. Students write a one page paper on how...

Students investigate the cycle of life by observing tadpoles.  In this biology lesson, students utilize the Internet to read stories, observe pictures, and listen to sounds of frogs.  Students create a poster board collage...
