3, 2, 1, blast off!
Third graders explore our solar system: the Sun at the center, eight planets in order, and the Moon traveling around Earth. They learn that the Sun is a star, that Earth's spin causes day and night, and that the Moon seems to change shape in phases over about a month. Many classes compare the planets and look at constellations. The click moment comes when a student explains that the Sun doesn't really move across the sky, Earth is spinning!
Space is huge and far away, so we bring it down to kid size. These moves do the trick.
Play the Moon Song and have kids act out each phase with their hands: a sliver, a half, a full circle. Use it as a warm-up all week. Music helps the order of the phases stick.
Why it works: a catchy, repeating tune gives the brain a hook to hang words on, so sung text is remembered better (Wallace, 1994).

Why it works: going from real objects to pictures to symbols is a core recommendation of the U.S. Department of Education's elementary math guide.
Try it withSolar System Sequencing Planets ActivityActivitiesOpen it →Have kids draw the Moon each night on a calendar for a month. Then look for the pattern together. Real observations turn moon phases from a picture in a book into something they've seen themselves.
Why it works: pairing a picture with each word gives kids two ways to remember it, a well-tested principle of how people learn (Mayer, 2009).

Most 3rd graders study the solar system, the Sun as a star, the order of the planets, day and night, and the phases of the Moon. Exact topics vary by state.
Earth spins on its axis once about every 24 hours. The side facing the Sun has day, and the side facing away has night.
The Moon doesn't really change shape. As it orbits Earth, we see different amounts of its sunlit side, which creates the phases.
Look at the Moon together each night and draw it, or use a flashlight and a ball to show day and night. Stargazing on a clear night is a great family activity.
