Beakman explains why your house creaks at night and then explains the purpose of snot and mucus in your nose.
Beakman uses the laws of gravity to explain why people don't fall off the round world. Galileo shows the effects of gravity. Next, Sir Isaac Newton explains inertia and how a seat belt helps save lives.
Beakman explains the cyclical process of rain and evaporation. The sun warms up water in a puddle, turning it into invisible vapor. As the vapor rises it cools, which makes it condense into drops that form clouds.
In the volcano segment, Beakman shows the process that a volcano goes through creating magma, and then a volcanic eruption.
