This is an illustrated article about how Aboriginal people's traditional knowledge demonstrates an understanding of physics, biology and chemistry and how Aboriginal people gather knowledge through observation, testing, trial and error, adapting and retesting. Written by Kudjala/Kalkadoon Elder from Queensland Letitia Murgha and intended mainly for teachers, the article focuses on the knowledge of the Aboriginal people of the rainforest about: the properties of materials; the use of forces, heat and water to remove toxins from seeds; how a spearthrower works as a lever; and that a firestick works because friction creates heat.
