For a class of 30. Microbes can tolerate minor changes in osmotic pressure but may be killed or inhibited by the osmotic pressure exerted by high concentrations of salt or sugar. Students observe the effect of 6 concentrations of sugar or salt on 5 food spoilage microbes. The application of this principle to food preservation methods is addressed. Requires 7 days from setup to completion. Note: Order the kit with the perishable materials (all . items) included or with a prepaid coupon to request perishables later at your convenience.

Grades 5–10. This complete STEM-based curriculum guides students through the culturing and presumptive identification of common microbes on innovative LaMotte® BioPaddles®. Each paddle contains microbe-specific media enclosed in a sterile vial. Explore and identify microbes that students culture from popular dairy products such as milk, yogurt, and kefir. Activities and topics include probiotics, fermentation, pasteurization, and shelf life. Students work in teams to design and apply science, technology, engineering, and math concepts to the exploration of microbes that they encounter every day. Activities develop critical-thinking skills and emphasize engineering as a key component. Kit includes teacher’s manual, student guide, and presentations on CD-ROM; magnifying lenses; and LaMotte® Tryptic Soy/Rose Bengal BioPaddles® (also sold separately to perform additional activities included in the manual). Kit also includes access to the free LaMotte® BioPaddles® Colony ID™ Lite App to compare “unknown” microbe growth on the BioPaddle® against a library of photos. Note: This item is shipped via ground from the manufacturer in Maryland on Mondays and Tuesdays only, and delivered Wednesday through Friday only (depending on delivery location). Please allow 2 weeks advance notice with specific Monday or Tuesday shipping date. 653598 Kit Each $82.50 653579 Tryptic Soy/Rose Bengal BioPaddles Box of 10 $48.85 154711P Spicy Inhibitors Kit (with perishables) Spicy Inhibitors Kit Beginning—Easy to perform; requires no experience in microbiology. For a class of 30 students working in groups of 3. For centuries, spices have been used to preserve foods because they contain natural substances that act as inhibitors. Students grow 5 common food spoilage microbes on black pepper, clove, and chili powder agars and examine the inhibitory effect of these common spices on the microbes’ growth and/or sporulation. Application to food spoilage prevention and the history of the spice trade is discussed and can be easily integrated into a multidisciplinary educational approach. Students practice aseptic technique and microbe culturing. Note: Order the kit with the perishable materials included or with a prepaid coupon to request perishables later at your convenience. Contact us or return the coupon to request materials. Keep bacterial and fungal cultures at room temperature; do not incubate or refrigerate. 154711 Kit (with prepaid coupon) Each $106.60 154711P Kit (with perishables) Each $106.60 653598 LaMotte Milk Microbe Hunter Activity Kit
