Product Information
What turns grape juice into wine, milk into yogurt and cabbage into sauerkraut? In each case, microorganisms break down organic substances, causing the food to ferment. With this kit, students can conduct three easy-to-do experiments that will allow them to observe the fermentation process. This laboratory is useful for teaching students about the relationship between scientific research and practical applications. Developed by Ed Alcamo. Includes materials for 30 students — stain, grater, wax paper, yeast, non-iodized salt, microscope slides, thermometers, droppers, toothpicks, and a teacher’s guide with background information.
