    This lesson is probably my favorite and it can be done at the aquarium or even in a classroom. In a classroom, the Sonde really isn’t required and all that is really needed is the data sheets and supporting file. Introducing the students to properties of gas and liquids while comparing the idea of how dissolved gases behave in liquids by relating it to a can of pop gets students thinking about the conclusion, which is then supported when they graph the data. This can be expanded upon by having students think about bodies of water in their community: have them think about the temperature and use their graphs to find what level of dissolved oxygen they predict would be present. This could help them predict what fish species will be present by using the fish table in the supporting file.
