The most effective way for children to learn about science is through hands-on experience, not through memorising theory. That principle is at the heart of Waldorf science teaching, and is the basis for this invaluable book. The authors explore the nature of 'phenomenological' -- experiential -- science' and how it can help middle-school students engage with physics, and stimulate observation and wonder. The book has step-by-step experiments that demonstrate how to approach science in this lively, real-life way. It is an essential book for any teacher who wants to bring this kind of fulfilling interaction into their classroom.

'What Is a Gas?' provides a simple explanation of matter, a description of gases, and gives examples of how gases can change into different shapes. The photographs and simple sentences help early readers grasp these concepts quickly.
