Curated OER
An Enzyme- Substrate Model
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.

Enzyme Activity: An Inquiry Based Approach
Using an inquiry approach to studying biochemical reactions, cooperative teams of high schoolers investigate hypotheses about living materials that contain enzymes which break down in hydrogen peroxide. They perform experiments,...
Curated OER
Enzyme Grabbers
Students perform simple experiments to show properties of enzymes through studying how apple sauce can turn into apple juice and experimenting with papaya seeds. Students witness how enzymes speed up reactions through witnessing the...
Curated OER
Enzymes and Jell-O
Learners test for the presence of enzymes in fruit and the specificity of those enzymes. They identify the susceptibility of enzymes to certain environmental factors such as temperature and pH in the enzymes environment.
Curated OER
ISOLATION OF DNA FROM ONION
Students perform a laboratory exercise designed to show how DNA can easily be extracted from onion cells. They conduct an optional test for the presence of DNA using standard lab equipment.
Curated OER
Polymerase Chain Reaction Activity
Students explain the importance and function of enzymes. They compare and contrast the processes of DNA replication and polymerase chain reactions. They practice using new vocabulary as well.
Curated OER
How do Restriction Enzymes Work?
Students discover how restriction enzymes work, while learning the importance of restriction enzymes in studying DNA structure.
Curated OER
Applied Evolution: How Will We Get There from Here?
Students explore the basic process of natural selection and how people can manipulate that process today. The consequences of natural selection on daily life and the implications of evolutionary biology in basic and applied science is...
Curated OER
Restriction Enzymes
Students explore enzymes and enzyme combinations. They examine and cut up and practice matching DNA sequences.
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
Small Intestine, Pancreas, Liver, and Gall Bladder
In this small intestine, pancreas, liver, and gall bladder worksheet, students fill in the blanks with information about these structures of digestion. Students research information about organ of the digestive system given.
Curated OER
Proteins
In this biology learning exercise, students identify and locate various vocabulary terms pertaining to types of proteins. There are 22 biology terms located in the word search.
Curated OER
Lactose Intolerance
Learners are taught how enzymes enable chemical reactions to occur a body temperature and how the lack of enzymes in the body can cause problems in the break-down and absorpion of nutrients. They match up different enzymes with the...
Curated OER
Topic: Math, Chemistry, and Food
Students listen as the teacher tells the story of Sisyphus rolling the stone up the mountain. Students prepare two batches of jello, one with fresh pineapple, and one with canned pineapple. While the jello is setting, students work on...
Curated OER
Enzymatic Reaction
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.
Curated OER
Toothpick Breakdown
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.
Curated OER
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.
