Fourth graders model the activity of an enzyme acting on a substrate and observe relationships. Have students place toothpicks in a pile. One member of the team should break as many toothpicks as possible, in 10 seconds.

Many physicals include a blood glucose test, but what are doctors actually testing? Scholars graph and interpret blood glucose data, allowing them to observe the differences in lactase persistence and draw conclusions. They then connect...

Young scholars applied various mathematical analyses to interpret their data. By using the resulting DNA fragment patterns from several enzymes students established a possible evolutionary relationship among the mice.

Determine the number of possible genetic codes. Class members are challenged to determine the number of possibilities of a genetic code that is 20 bases long. They continue to explore the average lengths of broken RNA molecules.

Students discuss as a class the need for a healthy diet. They bring in a food product and analyze the nutrition label. Using the labels, they complete a worksheet and chart the nutrients found in beef. They use a scale to see how...

Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.
