Product Details

Students observe microbial growth in their personally contrcuted Winogradsky column with soil collected from their surroundings. Repeating the soil microbe-growing technique—made famous by the Russian microbiologist, Sergei Winogradsky—is fun and motivating. Over a several month incubation period, students will witness an array of protozoa, fungi, bacteria and algae as their Winogradsky column goes through its successive stages. Includes enough materials for 10 Winogradsky columns (chemical nutrients, wooden stirring sticks and complete teaching instructions).

Complete for 10 students groups. You supply the mud! The 10 columns included in the kit can be resued.
