Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

Students discuss the functioning of the digestive system and the specific enzymes present. They observe the action of amylase on starch to identify characteristics of enzymes then perform an experiment on the effects of temperature on...

Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

Students test for the presence of enzymes in fruit and the specificity of those enzymes, as well as to identify and show the susceptibility of enzymes to certain environmental factors (temperature and pH) originating in the enzyme's...

High schoolers investigate the enzyme catalase. In this enzyme lesson plan, students observe a normal catalase reaction, they observe liver tissue, potato, chicken and apple for the enzyme catalase and they study the effects of...

Students watch a demo which is a modification of an enzyme lab which is done as a "magic show". It's primary purpose is to tickle the curiosity of the student and grab interest before discussion of enzymes. It is also used to stimulate...

Young scholars participate in a modified demo enzyme lab, a "magic show." The purpose of the demo is to tickle the curiosity of the student and grab their interest before discussions of enzymes. Its purpose is also to stimulate problem...

Young scholars compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...

Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.

Why is lactase important? Biology scholars explore enzyme function in a structured inquiry lab. The activity tasks lab groups with observing how temperature and pH affect enzyme activity, as well as determining which milk products...

Young scholars 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.

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...

Pupils examine the effects of specific enzymes on samples of liver tissue, muscle tissue (chicken), apples, and potatoes.

Pupils 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. 

Students determine the meanings of concentration, surface area, and catalysis through an experiment. In this activity about chemical reactions, students participate in an experiment. Students complete three different parts of the...

High schoolers 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...

Biology learners investigate the effect of sucrose concentration on yeast alcoholic fermentation. During the lesson,they compare and contrast the processes of cellular respiration and alcoholic fermentation. They design an experiment to...

Young scholars 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.

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.

Students 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...

Learners 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.

Fifth graders make cheese using two different methods. In this cheese making instructional activity, 5th graders make rennet cultured cheese following the step by step directions. They also make cheese using a genetically engineered...

Sixth graders design and conduct an experiment with milk to investigate how temperature affects bacteria growth. They, in groups, construct a hypothesis, perform the experiment and then record and present the results.

Students develop an understanding of the decomposition process and the parameters which influence the rate at which it occurs.
