pressure, effect of mass, etc. in order to make it better/faster. A single toy can
cover concepts that are otherwise taught in separate lessons throughout the year. Problem-solving
thus can be one of the important methods for science learning. Children use chart, write down
problems, reasons, solutions, that reflect on the science learning taking place. Books on science then
become meaningful and useful that finally structures their thinking. It helps cognitive development of
children and solves many of the pedagogic problems such as application of knowledge, integration of
theory and practice, etc. It is a process from experiencing to organized form of knowledge, rather
finding a method to provide the organized knowledge.
