The lesson will explain what the moon is and does. The Moon is an object that moves around the Earth in orbit. Other planets, not just Earth, also have their own moons. Students will think of another planet that has a moon. Students will also think about times they've seen the Moon make different shapes.
Then, students will be introduced to the different Moon phases: full moon, gibbous moon, half moon, crescent moon, and new moon. Each phase is lit up a different amount by the Sun. A full moon is fully lit up, and a new moon is not lit up at all. They will match the Moon phase to its corresponding image.
