P7F have been experimenting with Buoyancy and Density as part of their science project. We have experimented with how a solid object could be made to float on water by manipulating some Plasticine.
We have experimented with how the density of water will change the ability of an object (an egg) to float by adding salt to it.
Finally, we experimented with the density of different liquids. We predicted whether honey, fairy liquid and oil would float or sink on water then tested our hypotheses.
