The Effects of Heat and Acid on the Enzyme Catalase

Scholars learn about kinetics and buffers as they use qualitative and quantitative methods to understand enzyme rates and buffer capacity. The application of Beer's Law and spectrophotometry solidifies pupils' knowledge in the first of...

Students observe the effectiveness of detergents on breaking down proteins.  In this investigative lesson plan students participate in an activity that shows how proteins are broken down in gelatin and fill out a worksheet. 

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...

How can you quickly demonstrate the concept of enzymes and their activity within a cell, specifically increasing the timeliness of a chemical reaction? Individuals view a short video that demonstrates this concept in graphic animation...

Hydrogen peroxide bubbles might look painful on a cut, but they are actually doing an important job. The video explores enzymes by allowing learners to see active sites on enzymes and how substrates, like a key fitting a lock, fit...

Many people know enzymes help with digestion, but few realize enzyme production decreases with age, making it more difficult for bodies to digest certain foods. A worksheet offers 28 fill-in-the-blank and short-answer questions over...

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.

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

How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...

Milk the resource for all it's worth. Young biologists perform assay techniques to test the digestion of protein. They place bacterial samples, fungal samples, trypsin solution, and distilled water on a milk-agar plate to see the effects...
