Science 4 Inquiry
Enzymes in Action
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.

The Effects of Heat and Acid on the Enzyme Catalase
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!

Working with Immobilized Enzymes or Microscopic Organisms
Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.

Investigating Enzymes Used in Laundry Detergent
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.

Investigating Factors That Affect Rate of Enzyme Action
Students explore the properties of enzymes. In this chemical reaction lesson plan, students explore enzymes through a Web-quest and investigative study. Students will collect and summarize data and create a class presentation. This...
Curated OER
Enzyme Grabbers
Young scholars perform two experiments to show the properties of enzymes. They use pectinase to produce apple juice from applesauce to show enzyme action and then taste the difference between raw and boiled papaya seeds as evidence of...

Enzymes in Action: An Inquiry Approach to the Effects of Enzymes
Students experiment with enzymes as key components of chemical reactions in all living things through this series of lessons.
Curated OER
Enzymatic Action
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...
