Module 7 Revision Guide - Chemistry
Two versions of this handout are provided, the second with more detailed information on the same topics. Chemistry aces survey chemical reactions, heat energy transferred, and the action of enzymes by reading this resource. You can...
Curated OER
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 Activity: An Inquiry Based Approach
Students 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 conditions the...
Curated OER
Enzyme Activity: An Inquiry Based Approach
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...
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.
Curated OER
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...

Investigating an Enzyme-controlled Reaction: Catalase and Hydrogen Peroxide Concentration
Are you looking for a way to measure cellular respiration? Try it with pureed potatoes. With some standard high school science equipment, biologists can perform an investigation and collect data surrounding byproducts of respiration. You...
Curated OER
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.
Curated OER
Enzymes
Tenth graders observe enzyme activity. They discuss the relationship between drug use and enzyme activity.
Curated OER
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
Alcoholic Fermentation in Yeast
Biology classes will bubble with excitement as they complete this assignment. Beginning with an informative overview of cellular respiration and fermentation processes, the highlight comes as an experiment in determining the rate of...

Milk—How Sweet Is It?
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...
Curated OER
Enzymes in Action
You can use these easy and inexpensive labs to demonstrate enzyme activity.
Curated OER
DNA Detectives
In order to understand DNA fingerprinting, advanced biology aces divise a crime scenario and analyze three different samples of lambda DNA. This creative lesson plan provides practice with micropipettes, electrophoresis boxes, and other...
Curated OER
Identification of Gram Negative Bacilli
In this biology worksheet, students review the procedures used to complete the lab activity and then examine the purpose and add the information while answering the questions.

7.012 F’04 Problem Set 1 ~ Biology
Course identification information is included in the upper left corner as well as within the title of this learning exercise. If you overlook or remove that information, you are left with a tremendous college biology assignment. There...
Curated OER
Extracting DNA from Your Cells
Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....
Curated OER
Were the babies switched? – The Genetics of Blood Types
Human biology or genetics learners apply their knowledge to a unique situation: two newborn baby girls being possibly switched in the hospital. The engaging activity ends with a Punnett squares assignment in which pupils evaluate whether...
Curated OER
Amylase Enzyme In Saliva
Students test for amaylase enzyme in a variety of substances. Student pairs perform a series of tests to determine how long it takes the starch sample to change to sugar molecules and the blue color to disappear when various saliva...
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
Simulation of Gene Splicing
Students use the exercise as a prelude to a "wet" lab or as a substitute for such a lab. It correlates well with colony transformation labs. This lab is recommended for students what have difficulty with the abstractions that genetic...
Curated OER
Catalase and Catalysis
Students explore enzyme catalysis through a series of experiments. In this chemistry lesson, students determine the factors affecting catalysis. They explain the different uses of this process.
