SCIENCE WEEK 2013
DAY ONE: ASSEMBLY AND CLASS EXPERIMENTS WITH
FIONA BUCKLEY
Experiment: Solar Powered Desalination
A large plastic water bottle and cling film is constructed with salty water inside. A small collection jar is placed in the centre of the plastic bottle where it can receive warm sunlight. The sunlight will make the water evaporate away from the salt and the jar should contain water that is a lot less salty than the water that was put in the beginning of the experiment.
Experiment: Powerful Pondweed
Pondweed is submerged in water. A glass is placed over it in an effort to capture the bubbles of oxygen as they are produced by the plant. As days pass more oxygen should be produced and this should be more obvious as a larger bubble appears at the top of the glass covering the pondweed.
