- Unit 1 Scientific Learning Science is a way of finding things out: by looking closely, testing fairly and asking many people. You can do all three yourself. Science and research
- Unit 2 Information and Communication Technology Messages, money and photos now travel as numbers. How do the machines that carry them work, and how do we stay safe among them? Technology
- Unit 3 Living Beings and Their Structure Every living thing, from an ostrich to the microbes in gundruk, is built of cells, and scientists sort all life by what they are like. Living things
