Earth's Spin & Orbit
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

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?

Check understanding
- 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)
