2.1.2 Discussing your results

Figure 2

You should have now completed this week’s experiment and be ready to share your findings with your fellow learners.

If you would like to share an image of your experiment, you can do this by photographing or scanning your graph and attaching the photograph file with your forum post.

  • Did the water, salt water and oil behave the same way as Janet’s did?
  • Did the liquid you chose yourself perform how you expected?
  • Can you think of any other substances where the solid state would float on top of the liquid state, like water?
  • Why do you think the ice floated, while the frozen oil did not?

Remember, science is often about collaboration – did other learners have broadly similar or vastly different results? Why do you think that might have been?
