You are a park ranger who has to transport a rare echidna egg to a city zoo. You go to the desert of Australia to collect the egg but you lose the container. Use the materials listed above to make another container. To make things even more difficult, you now have to drop the container with the egg inside it from the top of a cliff for another park ranger 2.5 metres below to pick up. Children construct containers and test drop from various heights.
Children draw plans and flow charts that show all stages of construction and testing.
They write a self-evaluation of the entire process, including feedback on success or failure. Other Technology Activities Take a virtual tour of a traditional farm house here .
