We have been learning about the circulatory system and how our bodies work. This investigation shows how osmosis works in the human body only we used jelly babies and conducted fair tests to see what happened to them in different liquids. We made predictions, measured the length and weight of each jelly baby before placing them in 20ml of water, milk, oil and cola. We left them for 2 days to see what happened, then observed and recorded our results. Then we wrote our conclusions based on our findings.
