Ilia Podendorf is a science teacher who encourages children
to work on their own and to investigate and solve problems as
scientists do. Doing experiments, like the ones outlined in this book,
not only helps children develop better concepts but, incidentally,
improves reading skill and the capacity to follow directions
intelligently. Thus children become equipped to explore the ever-
expanding world of knowledge to which science leads.
By doing the experiments in this book, children see or hear or
otherwise observe what happens in certain situations. When they
learn what happens in a very small part of the universe they acquire
knowledge that helps to explain events in a larger universe.
Doing these experiments is fun. This is a good reason to do them
for children can learn while having fun. But there is a more basic
reason. Through experiments children get first-hand knowledge that certain
things do indeed take place. The knowledge gained through
experimenting, supplemented by other types of learning, enables
children to build concepts with which to interpret the world
around them.
