From our teachers' playbook

Hot, cold, rocky, gassy, and one just right

What do 3rd graders learn about planets?

Third graders get to know each planet as its own world. Mercury is closest to the sun and has almost no air. Venus is the hottest, wrapped in thick clouds. Mars is red and rocky, Jupiter is the biggest, Saturn has the brightest rings, and Uranus and Neptune are icy giants. They also learn how Earth's spin makes day and night, and how its trip around the sun takes one year. The click comes when kids realize Earth is the only planet we know of with liquid water and life, and they can explain why its distance from the sun matters.

Our favorite ways to teach planets

Each planet has a personality. These moves help kids remember who's who.

Planet song warm-up

Start science with the planets song and have kids point to each planet on a classroom chart as it's sung. After a few days, sing it with pauses and let the class fill in the missing planet. Fun, fast and memorable.

Why it works: words set to a repeating melody are easier to recall than the same words spoken (Wallace, 1994).

One planet, one fact page

Assign each group a planet like Mercury. They read a fact sheet and create a "planet passport" with size, temperature and one wow fact. Then groups present so everyone learns all eight.

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).

Model the solar system

Kids build a hanging or paper model of the solar system, placing planets in order. Ask, "Why are the inner planets rocky?" Building the model helps kids remember order and distance.

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.

Planet questions parents and teachers ask

What do 3rd graders learn about planets?

They learn the eight planets in order, how inner and outer planets differ, key facts about each planet, and how Earth's rotation and orbit cause day, night and years.

Which planet is the hottest?

Venus is the hottest planet, even though Mercury is closer to the sun. Venus has thick clouds that trap heat like a blanket.

What causes day and night?

Earth spins on its axis once every 24 hours. The side facing the sun has day, and the side facing away has night.

Which planet is the biggest?

Jupiter is the biggest planet. More than 1,000 Earths could fit inside it, and it has a giant storm called the Great Red Spot.
