What house hold plastic will float?

Last week we 'Engaged with Science' by conducting an experiment to see what house hold plastics would float and which would sink.
We learnt about fair testing, how to write a scientific report and how when variables change, it can influence the results of the experiment.

In the first experiment we tested which plastics would float and sink in water that was still and not moving. When we repeated the experiment we made the water move representing the waves and currents in the ocean. Interestingly the results were very very different.

Here are some examples of our reports, conclusions we made and data we gathered. The students did very well to relate their findings to the big picture of plastic pollution in the oceans.
