Ocean Currents Science Experiment
Every child who has ever watched Finding Nemo has heard of ocean currents. Seriously educational stuff there folks! While Finding Nemo is definitely not the most educational movie of all time, it can really spark curiosity in kids to find out more about ocean currents, like the East Australian Current, and how they are formed. This ocean currents science experiment is a fun way to see currents form right before your eyes!

Materials needed for the Ocean Currents Science Experiment:
Cold Water
Ice
Boiling Water
Red and Blue Food coloring
Clear or white large baking dish
First, fill the clear baking dish about 1/3 full with cold water and add a few drops of blue food coloring. You won’t want the blue to be too dark or you won’t be able to see the currents forming.
Add a 1-2 cups of ice to the cold water and stir. Let it set for a few minutes for some of the ice to melt. Our goal is to have very cold water.

Lukewarm water will not give you the same results. (Trust me on that!)
While the ice is melting, boil about 4 cups of water. Add red food coloring to the boiled water, this one you will want to make darker.
Once both sets of water & dye are ready, gently pour some of the boiling water into a corner of the baking dish filled with cold water.

Then, watch as currents form right before your eyes!
The hot water will push through the cold water creating currents. In the ocean these are faster moving strips of water (like the East Australian Current…)
As an added bonus, we got to see some eddies form! Eddies are circular moving currents and you can see them very clearly in this picture.

Eventually the water mixed together to create lukewarm (and purple) water which is what it also does in the ocean.
