Vartak, Rekha; Ronad, Anupama; Ghanekar, Vikrant – Journal of Biological Education, 2013
Scientific investigations play a vital role in teaching and learning the process of science. An investigative task that was developed for pre-university students is described here. The task involves extraction of an enzyme from a vegetable source and its detection by biochemical method. At the beginning of the experiment, a hypothesis is presented…
