Space Activities for Kids Ages 4–8

Quick answer: Four short space activities need only paper, crayons and a ruler: walk the Moon's orbit, measure "an inch a year," line up the eight planets, and talk about our one star. Each uses a fact checked against NASA.

We publish the book Space Explorers mentioned near the end of this page, and we say so there.

Activity 1: Be the Moon (ages 4–8, 5 minutes, needs a clear floor)

Fact: The Moon is tidally locked to Earth, meaning the same side generally faces Earth. People did not see the far side until a Soviet spacecraft flew past in 1959.

Try it:

  1. A grown-up stands still. They are Earth.
  2. Your child is the Moon and walks slowly around them in a circle, always keeping their face pointed at the grown-up.
  3. Ask: "Which side of you can I see?" (Only the front.) Then ask what is happening to their back.
  4. Swap roles.

Why it works: It gives children a physical way to picture why we only ever see one side of the Moon.

Activity 2: The Moon moves an inch a year (ages 5–8, 5 minutes)

Fact: NASA says the Moon goes around Earth at a distance of about 239,000 miles (385,000 kilometers), and that it is slowly moving away, about an inch farther each year.

Try it:

  1. Show your child one inch on a ruler.
  2. Ask: "If your age is 7, how much farther away is the Moon than when you were born?" (About 7 inches. That is our arithmetic from NASA's "about an inch a year.")
  3. Draw the Moon and Earth on paper and a tiny arrow between them.

Talk about it: "Would we notice an inch?"

Activity 3: The planet parade (ages 4–8, 15 minutes)

Facts: NASA lists eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Mercury is the nearest to the Sun and the smallest planet; Jupiter is the largest.

Try it:

  1. Draw eight circles on separate cards and color each one a different way. The colors are up to your child; this is art, not a color chart.
  2. Put them in order from the Sun, then try ordering them from smallest to largest, using NASA's page as the answer key.
  3. For ages 4–5, start with only three cards: Mercury (smallest), Earth (home), Jupiter (largest).

Rhyme tip: Make up a silly sentence with the first letters, M-V-E-M-J-S-U-N. Children enjoy their own sentence more than ours.

Activity 4: Our one star (ages 4–8, 5 minutes)

Fact: NASA says the Sun is the only star in our solar system, about 93 million miles (150 million kilometers) from Earth, and "only an average star in terms of size."

Try it: Draw a big yellow circle for the Sun, then ask your child to draw Earth far away on the other side of the page. Ask: "How far apart should we draw them?" (NASA says about 93 million miles, so very far; it's fine that the drawing can't be to scale.)

Safety: Keep this a drawing activity. Don't look directly at the Sun.
