Biosphere Web Trek

With this Web Trek to help you celebrate Earth Day, upper elementary and middle school students will visit selected websites to learn all about the biosphere and its interactions, including photosynthesis and the carbon cycle. For an extension activity, students will build their own mini biosphere in a recycled, plastic soda bottle. Click on the title above for the student Web Trek, and use the link below for the Answer Key.
