Year 8-1 Geography class enjoyed their Assessment Task Water Classification activity in the Science Lab.  We were learning about the classification and sustainability of water in the world, so that we can be more aware of the amount of freshwater on earth and consider how to use it more sustainably.

We filled the fish tank with water to show all the water on earth, we then extracted only 25 tablespoons of water from the tank and placed it in the large, clear jar labelled “freshwater.” Leaving 97.5 % saltwater in the fish tank.  We then moved water from the freshwater jar to show how much is groundwater and in another jar how much is in rivers and lakes.  The jars had very little water in them in comparison to the fish tank.  We considered all the percentages and graphed the results for the assessment task.  The students worked very cooperatively in the lab and in the following lessons to complete their Assessment Task Part A.  Assessment Task Part B will be conducted later this term showing how a catchment can be easily polluted with a variety of activities along the river before the water arrives in the ocean.  Thanks to Mrs Eloise Thomas for coming to our lesson in the lab to share with us the joy of water activities.
