The Discovery of Fullerenes
Carbon is the most common element on earth, so the innovative discovery of a new type of carbon molecule won the 1996 Nobel Prize. In the ready-to-go lesson, scholars learn about C60 and how it has opened up the entire area of...
Cornell University
Discovering Enzymes
Explore the function of enzymes through a series of lab investigations. Learners use household enzymes such as hydrogen peroxide to model the role of enzymes. The enzymes break down proteins with and without a catalyst.
