Evolution of Yeast—Guided- Inquiry Laboratory Kit
An evolutionary twist on a popular fermen- tation lab! Students investigate three varieties of yeast used in the food indus- try—baker’s, brewer’s and wine maker's. First, yeast is used as a model organism to determine whether respiration rates differ among types of yeast. Students then design their own investigations to test which envi- ronmental factors and food sources make these yeast thrive. Complete for 30 students working in pairs.

Effects of Disinfectants and Antiseptics on Bacteria—Student Laboratory Kit
Students thoroughly investigate and compare several antiseptic and disinfectant products, such as soap, alcohol and bleach. With the buzz in the media about bacterial resistance, you will definitely hold a captive audience while discussing this important topic! Complete for 30 students. Bacillus megaterium is required for this activity and available separately.
Analysis of Over-the-Counter Drugs—Student Laboratory Kit
Students test a variety of physical and chem- ical properties of actual over-the-counter (OTC) drug samples and then use their test results to analyze unknown pain reliever and antacid samples. OTC drug samples—pain relievers and antacids—and special-
ized equipment are provided in the kit. Complete for 30 students working in pairs. Fifteen 24-well reaction plates are required and available separately.

Cheese-Making—Student Laboratory Kit
Learn how fun it is to make cheese right in your lab! This kit teaches the basic process, adapted centuries ago, of cheese-making using a harmless bacteria and a fermen- tation-derived clotting enzyme. This
sneak peek into the industrial process of cheese-making will allow your students to appreciate the fairly specific temperatures and pH requirements of enzymes and the commercial value of bacteria!
Using Bacteria to Clean Clothes? Genetic Engineering in Action— Student Laboratory Kit
Today, genetically modified organisms (GMOs) are used in many ways to benefit mankind, from making insulin to improving detergents. In this easy-to-use kit, students investigate whether detergents that list GMO-derived enzymes as ingredients will “clean clothes” better than detergents that might not contain enzymes. Materials are included for 30 students. A Super Value Kit is also available for 75 student groups.

Transcription and Gene Expression in Bacteria—Student Laboratory Kit
Students incubate the nonpathogenic bacte- ria Serratia marcescens on nutrient agar at two different temperatures. The bacteria may be red, pink, white or colorless depending on whether the red pigment prodigiosin
is produced. Several specific enzymes are required for the synthesis of this pigment. Although the bacteria will grow across a wide temperature range, the genes for these enzymes are only transcribed below a certain temperature. Kit includes enough materials for 30 students. S. marcescens culture must be ordered separately.
