Marine Science Fun

Today, Noirin from the Explorer's Project came into our class to talk to us about marine science. She showed us some dried sea creatures, including a starfish, a seahorse, a sea snail and a set of shark's teeth! We then did an experiment to determine whether fresh water is heavier than salt water. 
We put red food colouring in the salt water and as you can see, we discovered it is heavier than fresh water!
