10. Purpose- to observe osmosis in action by placing gummy bears in solutions of various solute concentrations
We will place one gummy bear in a salt water solution and one gummy bear in tap water. We will also have a control gummy bear that will not be placed in water.

11. Hypothesis – Come up with one

12. Materials- gummy bears beakers water salt ruler scale

13. Procedures- Write as I explain
