Piaget views the child as a busy, self-motivated explorer who forms ideas and tests them, against the world without external pressure. Pre-schoolers are naturally born scientists who love to explore, examine and have an inquisitive mind in the things happening around them, They are eager to find out the how’s and why’s of the natural environment around them. Like scientists, children think, form concepts and solve problems. Children observe, infer, classify and reach conclusions. Therefore, it is essential for the teacher to identify how children learn and to select the content that is closest to the children based on interest, past experiences. To keep a balance between biological and physical science and to explore community resources that are available.
