Enzymes: Two Wet Labs and One Dry Lab

WARD470003-980
Which laundry detergent is the most effective? Some detergents work by using enzymes to break down the proteins that result in some clothing stains. Biology teachers Lynn and Bert Wartski designed this hands-on kit to let students determine the rates of enzyme reactions in tubes of gelatin.

Students bring in detergent from home, analyze the performance of the enzymes, then use factors such as cost to select the best overall detergent.

Includes materials for 30 students: ruler, overhead transparency, wax pencil, measuring spoons, measuring cup, stir sticks, glucose strips, graph paper, test tubes, gelatin and complete instructions. Grades 7–10.

Note: Laundry detergent is required but not included.
