Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

Enzymes: not just for breaking chemicals apart. Young biologists perform an experiment on potatoes. They first remove starch from potato extract. They then add the resulting liquid to samples of glucose-1-phosphate, glucose, maltose, and...

It's a win-win situation: learn about enzymes and get clean clothes, too. Young scientists add enzymes to a dilution of laundry detergent. They apply them to stained fabrics to determine the effectiveness of the enzyme-filled detergents.

How do green plastics reduce waste and environmental pollution? Budding scientists create and test a variety of compounds used in green plastics during an insightful experiment. Beginning with startling statistics and ending with...

Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

Why is lactase important? Biology scholars explore enzyme function in a structured inquiry lab. The activity tasks lab groups with observing how temperature and pH affect enzyme activity, as well as determining which milk products...

How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

The fifth lesson plan in the six part series introduces units of energy including calories, Calories, and joules. Scholars determine the energy released when eating a snack and during activity.
