Float and sink

 LI: to identify the bouyanty of an object.

This week for Science we learnt about how things/object sink and float. Things float becuase they either contain air inside of it or they are light becuase they are made out of plastic. Things sink bececuase they are heavy and don't contain air.

We got into partners and had to tes the size, weight, compostion (What its made out of), Prediction (If it floats or sink in water) and the Bouyancy result.

I found this task intresting becuse i did not know that a large wood would float .
