My Ocean Currents Experiment

McCahon has been using Thinglink for our learning, it's awesome! And you can add so much of your work into only one interactive image.
We have also been learning about Ocean Currents. This is what we have found-

• Cold salty water is denser and heaver than  warm or cold freshwater.
• That surface tension is the thing that holds small insects that can walk on water.
• We have also found a word which is Thermohaline it means currents caused by salt and temperature.
