Ocean unit - week 1

We started our Ocean unit this week - we got to have a good look at the difference between an ocean and a sea. We also looked at how much of the earth's surface is covered in water,

they drew a circle and divided it into 10 sections

and coloured 3/10 green for the land and 7/10 blue to represent the water. 

The girls also explored estuaries - they looked at the specialised plant life found there and did a cute activity to see how salt and fresh water mix.

One bottle was filled with salt water (we used bottled water rather than tap), another is filled with fresh water coloured blue. When the fresh water is first introduced into salt water it briefly forms a slight layer on the top then mixes together. 

They also worked on naming the oceans.
