Channel: GeoscienceAustralia
Date: 2020-04-22

This short video by the Geoscience Australia Education Team is targeted at primary students but is suitable for a wider audience. This video introduces the concepts of weathering and erosion by investigating why river pebbles are often rounded. Viewers can undertake an activity which demonstrates the process of erosion using sugar cubes. They are asked to predict what might happen (a hypothesis) and then observe what does happen and relate this to the natural environment.
