Kellydee Johnson▸ Task 4: Digital Systems

Option 3: Past and present technologies
Prep students will respond better to technologies that they interact with everyday. The Edison centre has some great visual / photographic resources of home appliances from the 1800's to the current year. We will use an old sheet and try and wash it in an old bucket with a piece of corrugated iron and then compare this to how we wash our clothes in the electronic washing machines. We will make some criteria to compare them to like time taken, effort needed & cleanliness achieved.
