A science experiment that investigates if evaporation can be reduced by covering a body of water.
Heating a liquid can cause it to vaporise and become a gas. For water, this process is called evaporation. Aboriginal peoples in Australia were aware of this and would cover their wells and waterholes in an attempt to conserve their water supply. Would this actually work? Let’s investigate!
