Year 9 Science Global Heating Experiment

September, being a month that includes threatened species day and considers environmental effects on the thousands of other species in Australia, it is timely that our Lakeside College year 9s are investigating how the air around us, and the other species, is warming.
Recently our year 9 science students completed an experiment (pictured) in our laboratory to look at the rate of heating of air above water, soil and sand when impacted by solar radiation. The sand is used as an analogue representing land that has no plant cover or organic content. The students found that the latter allowed more reflection of solar radiation, resulting in warmer air.
