Dry Ice Experiment
In Week 7, students from Years 7 to 10 performed experiments with dry ice.
They observed the sublimation (moving straight from a solid to a gas, bypassing the liquid stage) of the dry ice and how that can make a chunk skirt around the table with little to no friction.
They saw the acidification of water and the production of carbonic acid (H2CO3) and related it to how excess fossil fuel burning was leading to ocean acidification and the killing of ecosystems like the Great Barrier Reef.
Finally they observed the build-up of pressure in an enclosed environment, making a PET bottle into a makeshift rocket and launching it into the air.
