Experiment 3: Dried beans in a sealed container
Materials
• 1 small plastic tub with a flexible snap-on lid (for example, a small margarine, sour
cream, or yogurt tub). You want the lid to snap on relatively tightly, but not be screwed on
because it has to be able to pop up and eventually off.
• 1 to 2 cups of dried beans of any type (enough to almost fill the tub)
• 200 mL of water
Procedure
• Fill the plastic tub with enough dried beans to reach about 1 cm below the lid.
• Pour all the water in the tub and seal with the lid.
• Shake the container to make sure all the beans get wet.
• Leave the container at room temperature.
• Wait 24 hours and observe what happens to the lid.
