Science - Topic 4 Floating & Sinking

 L.I: To check which objects would float or sink. 

For science we did experiments on floating and sinking.  First we talked about floating, sinking and semi-float. After doing writing down all the information we know about floating and sinking we started the experiments. 

What is Negative and positive buoyancy?

Negative buoyancy causes the object to sink.

Positive buoyancy cause the object to float.

We checked the size, weight, composition, and made a prediction. For the first experiment nearly all the objects sunk and for the second experiment some of it floated and semi floated. 

I enjoyed this experiment because I enjoyed the part where we checked if it would float or sink.
