Beakman explains what the moon is and its shape. Liza dresses up as a giant moon while Lester shines a spotlight to act like the sun. Beakman is the Earth, and they show that, depending on where the moon is, it will change the light reflecting off of it. Therefore, we see different phases of the moon. To explain craters on the moon, Beakman sets up a large box of flour covered in paprika and drops a large rock into it to emulate space debris hitting the surface of the moon.
