Solids, Liquids and Gases has 13 experiments carefully chosen by the
Ontario Science Centre. With minimal supervision, children can explore
the three states of matter, what makes each state unique and how matter
changes from a solid to a liquid to a gas through evaporation,
condensation, melting and freezing. Filled with bright photographs, the
Starting with Science series provides valuable lessons about basic
science for five to eight year olds.
