As the first practical field trip of Rovers of Tamirabharani for the year 2019-20,a team of our students had a detailed hands on experience @ Manjolai. The adventure and explorative trip equipped our students in a study of temperature of the water, measuring the rate of flow of water and also preparing a detailed study of the macro invertebrates in the streams found. Using the foldscope the students prepared an insect chart of the common aquatic macro invertebrates and the biological sample found in the streams were viewed under the microscope.
