How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

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. 

Students explore the reaction rates of an enzyme-mediated reaction through experimentation. In small groups, they use everyday objects to demonstrate the effects of environmental variables on enzyme function. Students graph and...

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...

Scholars learn about kinetics and buffers as they use qualitative and quantitative methods to understand enzyme rates and buffer capacity. The application of Beer's Law and spectrophotometry solidifies pupils' knowledge in the first of...

Students explore reaction rates of an enzyme-mediated reaction. They examine the effects of environmental variables on enzyme function. Students collect, graph, and analyze data relating to the reaction.

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Students pretend to be enzyme that breaks toothpicks in timed intervals. They complete calculations to determine how many toothpicks are broken per second to determine the rate of reaction of the enzyme.

Students explore enzymes and what can inhibit and act as a catalyst for them.  For this enzymes lesson students complete experiments on enzyme properties.

Students explore the properties of enzymes. In this chemical reaction lesson, students explore enzymes through a Web-quest and investigative study. Students will collect and summarize data and create a class presentation. This lesson is...

Students discover enzyme to substrate specificity. The experiment uses samples of glucose and lactose in combination with the enzyme lactase. Students observe the reaction between the lactose and the lactase; the lack of a reaction...

Using an inquiry approach to studying biochemical reactions, cooperative teams of students investigate hypotheses about living materials that contain enzymes which break down in hydrogen peroxide. They perform experiments, practice...

Young scholars observe the effectiveness of detergents on breaking down proteins.  In this investigative lesson students participate in an activity that shows how proteins are broken down in gelatin and fill out a worksheet. 

Young scholars explore biochemical reactions mediated by enzymes in an inquiry approach. They are given two questions about the types of living materials that contain the enzymes that break down hydrogen peroxide, and under what...

Learners design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme...

Students work with models of substrates and of enzymes and test the digestion of lactose with lactase. They determine if digestion of lactose has or has not occurred.

Students observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other elements...

Students examine the characteristics of lactose and lactase.  In this enzyme lesson students study the lactose in milk and its rate of dissolution.

Young scholars examine what amylase is and its history.  In this digestive instructional activity students study the effect amylase has on starch and how temperature affects the rate of activity.

Become an immunologist for the day. Scholars elicit the use of the enzyme-linked immunoabsorbent assay (ELISA) to diagnose an infectious disease. Through the process, they learn about the immune system response to infectious diseases.

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.

Students explore the effect enzymes have on reactions. They demonstrate the process of enzymatic reaction by making cheese. after experimentation, they answer a series of questions.

Students explore organic compounds. Using humor, factual and conceptual correctness, students create a skit explaining organic compounds. Students include topics such as sugar, polymerization, unraveling of proteins, and substrates. ...

Students examine chlorophylls. They explore the absorbing pigments in a variety of plants. Through activities, students determine spectrophotometrically. They compare plant proteins from the family Brassicace to assess the level of...
