Break It Down: How Scientists Separate Mixtures discusses mixtures and the importance in science of being able to separate them into component substances.
Break It Down shows students three contexts in which separating a mixture is important.
Students learn about the separation of pure water from salty ocean water, plasma from blood, and the ingredients of a meal found in an ancient tomb. Each example features a different separation technique.
The book emphasizes that each technique uses the individual properties of the substances in the mixture in order to separate them.
