This Life Stinks!

View a video presentation comparing chemosynthesis to photosynthesis. Review the findings of the 2004 Ring of Fire Expedition that studied biological communities around the hydrothermal vents of the Mariana Arc. In...

Chemosynthetic communities of cold seep areas are considered in this instructional activity. Working in collaborative groups, marine biology or oceanography learners research and prepare a report about oxidation-reduction reactions...

Explorers set up Windogradsky columns with local mud so that they can culture microorganisms. After three and six weeks they make observations of the mud and the organisms growing in it. In this way they observe succession and relate...

Photosynthesis was discovered in the 1770s, but chemosynthesis wasn't discovered until 1977. While many have performed an experiment to show how photosynthesis works, the activity allows pupils to observe chemosynthesis. Scholars set up...

One of the most important biological processes: photosynthesis. [13:37]

View how autotrophs and heterotrophs use the energy of the sun to form the energy their cells need, ATP. Learners watch an informative video that details the processes of photosynthesis, learning where it occurs, what...

Students are given the unique opportunity to see the contrast between parts of a leaf that have photosynthesized and parts of the leaf that have not. This visual image helps students see the results of this biological process. At the...

Review the light reaction process of photosynthesis.

Compares and contrasts C3, C4, and CAM photosynthetic pathways. Digram of C4 reaction included.

Compare and contrast the energy generating processes of chemosynthesis and photosynthesis with this interactive resource.
