Floating and sinking, buoyancy, engineering, sustainability – the list of joyful explorations you can start from water play is endless.
At Little Scientists, we are all about spotting STEM opportunities in the everyday. Exploring with sparkling water, or to children more commonly known as fizzy water, might not be an everyday occurrence but is a fascinating way to introduce gases (in this case carbon dioxide) and if you have access to a soda stream, it could be even more fun!
One of our wonderful Local Network Partners up in North Queensland, Jim Callan, contacted me the other day to talk about a new STEM exploration called floating oranges. He told me that oranges with peel on float and if you take the peel o, they sink. He challenged me to nd out whether it worked for other fruit.
Oil at sea can be a problem. In 2010, BP’s Deepwater Horizon spill discharged 4 million barrels of oil into the Gulf of Mexico, of which only 810,000 barrels of oil were collected. It was the largest marine oil spill in history. As a result, much of the oil was washed ashore by the tide making the beach dirty and causing massive problems for wildlife.
