Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

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.

If you've ever felt a little drained ... try converting some ATP to ADP! Science scholars perform one of life's most important reactions using a simulated lab workbench. The fun-to-use interactive allows pupils to control the reactants...

Enzymes have a need for speed! What happens when they are forced to slow down? A well-rounded lesson plan from the K20 Center examines enzyme activity through role playing and a lab. Biology scholars work in teams and pairs to understand...

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...

Have you ever wondered why some people are lactose intolerant? Participants test simulated patients in a hands-on lab activity to find out! They learn about lactose intolerance by performing an experiment, analyzing data, and drawing...

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 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...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Would you believe that your digestive system stretches to five times your height?! Help your pupils to understand this relationship as they work through the laboratory exercise. The first instructional activity of a 12-part series is a...

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

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...

Can your biology class crack the Case of the Crown Jewels? Junior forensics experts try their hands at DNA restriction analysis in an exciting lab activity. The lesson introduces the concept of restriction analysis, teaches pipetting and...
