This activity will help you understand that the ocean is not like a swimming pool where water is stationary, but more like a river with deep currents. These currents have a huge effect on global climate and the movement of water in the Arctic Ocean acts as a pump driving the system of ocean circulation.
Ocean circulation relies on different densities of water falling and rising. The density of water is affected by salinity (the amount of dissolved salt) and temperature. With this activity, you can predict and observe how different types of water behave.
To prepare for this activity, you will need to prepare four different types of water for students to work with.
