Background For Teachers:
This activity demonstrates a variety of sea water properties. Density is addressed by station 1, 4, 5, and 6. The ocean is a layered system with the coldest, saltiest water at the bottom because it is most dense.
Station 2 illustrates a property of salt water that is meaningful in polar areas. Water with salt in it has to be much colder for it to freeze.
Station 3 shows how water pressure increases with depth.
Station 7 shows that waves do not move water but wind does.
