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!

Enzymes in Action
Students explore how enzymes are important in the chemical reactions of all living things. In this enzymes and catalysts activity students complete an activity to see how enzymes change living things.

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.

Enzyme Grabbers
Students 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 enzyme...

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...
Curated OER
Enzymes
Students explore enzymes and what can inhibit and act as a catalyst for them. In this enzymes lesson plan students complete experiments on enzyme properties.

Catalysts and Enzymes
Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

Enzyme Action
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.
Curated OER
Enzymes
Tenth graders observe enzyme activity. They discuss the relationship between drug use and enzyme activity.

Enzymes
Tenth graders test their saliva for enzyme activity. In this enzyme lesson, 10th graders conduct an experiment to test the enzymatic activity of their saliva. They relate the lack of certain digestive enzymes with alcoholism.

Bad Microbes in Food Processing
Students complete an experiment to determine if there are bad microbes in food processing.In this bad microbe experiment, students use apples to see how they react to oxygen. Students test apples with chemicals to observe the changes.

PhysioEx: Chemical and Physical Processes of Digestion
In this anatomy worksheet, students complete 22 review questions in the format of short answer, table completion, and fill in the blank after finishing an online virtual experiment about the chemical and physical processes of digestion.
Curated OER
Amylase
Students examine what amylase is and its history. For this digestive lesson students study the effect amylase has on starch and how temperature affects the rate of activity.
Curated OER
DNA Replication
Students create a model of DNA and simulate replication with their models in an activity that uses licorice, colored marshmallows, and toothpicks. Students also label a diagram of replication and indicate major parts of the DNA molecule.
