Water is a precious resource. Certain solutes can threaten that resource. To protect our water, scientists try to identify the presence of pollutants, and, even more importantly, to measure their concentration. For students, how can we drive home the importance of measuring things in the water that they cannot see? Easy – model it with something that they can see! Sports drinks are a great way to introduce solutions and concentration. The color helps students visualize that a solute is present and conductivity measurements can quantify the amount of electrolytes. Molecular visualization tools can be added in to then help students understand the process of dissolving.<br/> <br/>Join me for this session to see how the combination of data collection and molecular visualization tools can connect levels of representation and lead to meaningful student learning about water and solutions.<br/>
