Relevant examples of the inventiveness of Australian scientists are included throughout. We use our senses of sight, hearing, smell, taste and touch. To help our senses, we use various instruments and sensory aids. In this strongly activity-based chapter students explore how rockets work and investigate the planets of the solar system. There is a short, tantalising glimpse of the vastness of our own galaxy.

Vivid examples of natural disasters grab students' attention for later investigations of geological processes. This chapter discusses what an animal is and then explores the digestive, respiratory, skeletal and reproductive systems of various animals - land and aquatic. The investigations take students out of the classroom and into the local environment. Students are engaged in many stimulating activities for the investigation of energy, in many of its forms. 7 Sources of Energy Students learn that Australians are second only to people in the United States in their use of energy per person.
