Students were asked to work in small groups to design and conduct an experiment that explored the effects of osmosis in gummy bears in salt solutions. The task required students to apply their knowledge of osmosis, cell transport, and semi-permeable membranes as well as their knowledge of the skills and processes involved in designing a scientific investigation.

This group made a hypothesis, selected tools and materials, developed a set of procedures for conducting the four-day experiment, and developed charts for recording observations and data. They then conducted their experiment, adjusting their procedures as necessary. They graphed and analyzed their data, considered sources of error, and generalized and drew conclusions based on their data. They used their generalizations to ask new questions and make new predictions, including whether the effects they observed would also be seen if they used potatoes instead of gummy bears.

After the experiment, each student completed an individual lab report.
