Collect gummy bears. Keep a few for control and for snacks.
Heat 1 cup of water on stove. Slowly add salt and stir. Continue adding salt until it no longer dissolves and a few salt crystals remain at the bottom. Poor the solution in a bowl and let mixture come to room temperature.
Repeat process with sugar.
Fill last bowl with normal water.
Place a few gummy bears in each bowl and keep a few for control.
Observe what happens and discuss osmosis.
Further exploration – change salt or sugar contents, test different types of liquids, try different types of gummies, weigh the bears before and after.
