註釋Most of the materials around us contain blends of more than one substance. These are mixtures and solutions. Seawater, for example, is a solution of salt and water. The engaging text and vivid illustrations in this book will help readers understand how mixtures and solutions form and how they apply to everyday life. Topics include - the difference between mixtures and solutions - how solutions may be diluted or concentrated - how distillation and filtration work - the principles of osmosis. Teacher's guide available.
