Buoyancy

 LI: To test the buoyancy of different objects.

This week in Science Tech we experimented with the different buoyancys that different objects have. The objects that we were experimenting with were Tennis balls, Large and Small marbles, a table tennis ball, and a golf ball. We also experimented with some different shaped blocks, that also composed of different materials.

When things float the term to use is 'That object is positivley buoyant' and when an object sinks then the term to use is 'That object is negativley buoyant'. Water rises when the weight of the object in the water is greater than the amount of weight that the water displaces. Mass is the same as how 

I enjoyed this task because it was very intereging seeing if the object would float or sink.
