Science Sunday: Investigating How Submarines Sink and Resurface

Some of the most active learning can be done when a student is simply curious about a topic, and eager to experiment with it. So in this week's Science Sunday segment, we're exploring how submarines can sink and resurface by making a cartesian diver with just a condiment packet and a soda bottle:

• Learn more about the science behind cartesian divers.
• A link to the Exploratorium where Kristen says she got the inspiration for this demonstration.
• Learn more about how this applies to submarines.
