How can you tell they’ve got it: Earth's Spin & Orbit?

If they’ve got it, you’ll see things like: Demonstrate with a globe or ball that Earth's rotation causes day on the Sun-facing side and night on the opposite side; State that one full rotation takes about 24 hours (one day); State that one full orbit around the Sun takes about 365 days (one year). Or just try it together: Can your child explain that we have day and night because the Earth spins, and that a year is the time it takes Earth to go all the way around the Sun?

Earth's Spin & Orbit

Your child knows the Earth moves two ways. It spins once a day, which gives us day and night. It also circles the Sun once a year.

In curriculum terms

Understand that Earth moves in two ways: it rotates (spins) on its axis once every 24 hours causing day and night, and it orbits (travels around) the Sun once every 365 days, which is one year
