We have been studying passive transport within a cell and the process of diffusion and osmosis. The students wrote a creative story that contained diffusion or osmosis in the storyline. They picked a plastic animal that is one of the characters in the story, an inspiration for the story. This allows the children to make a connection to these processes and everyday situations. This process is also used by the eukaryotic cell to move molecules in and out of the semi-permeable membrane.
