Systems

How do systems meet our needs?

1. Students investigate their basic needs, as well as their wants, for food, clothing and housing. Ask them to complete a retrieval chart that distinguishes between food, clothing, housing needs and wants. 2. List systems in our local community. The journey of a letter at Australia Post. List steps in a procedure e. from seed to supermarket || **__ Core Tasks __** 1. Have students investigate the possible sources for satisfying needs and wants, eg shops, farms, factories, home produce, community organisations, and complete a retrieval chart. 2. Select two systems in our community and compare and contrast. (Venn Diagram) 3. Write an explanation explaining a system process. || **__ Extension Tasks __** 1. Why are some people’s needs not met? Identify examples (including countries) and possible reasons for this inequality. 2. Compare 3 systems in terms of inputs/outputs and how they benefit us. Eg. Digestive system Desalination plant Photosynthesis 3. What if a major system we depended on failed to work? Disease/oil spills Evaluate the implications. ||  || Product- How will you present your knowledge? Password: student || Miss Keys has encountered a PROBLEM! Try this until she solves it!
