Space

Grown-ups

Space Month: July

July's four space missions, one a week, made from things you already have at home. Do one, tap "I did it!", and a badge goes in your Sky Book.

Week 1: Take a planet walk

You need: a ball for the Sun (a basketball, softball or ping-pong ball), nine sticky notes or the printed signs, a long sidewalk, path or park.

  1. Pick your Sun ball on Planet Walk. It tells you how far apart the planets go and how big each one is.
  2. Put the Sun down and walk, counting steps, to each planet. Leave a sign at each one.
  3. Stop and look back at the Sun from Neptune.

Why it works: The planets are tiny and far apart. Most of the solar system is empty space, and a walk is the only way to feel how much.

Week 2: Spot the space station

You need: Peabody's Station Passes for your area, a clear evening or morning.

  1. Find the next visible pass this week, and set a reminder.
  2. Go out a few minutes early with a grown-up and face where it appears.
  3. Look for a steady bright dot moving smoothly across the sky, with no blinking lights. Wave: people live there.

Why it works: The station goes around Earth about every hour and a half. You see it because sunlight is still shining on it, high up, after it's dark where you are.

Week 3: Count the stars in a tube

You need: a paper towel tube, a clear night, a pencil and paper.

  1. Go outside with a grown-up and wait ten minutes for your eyes to get used to the dark.
  2. Look straight up through the tube and count every star you see in the circle.
  3. Do it three times in different parts of the sky and add them up.
  4. Try again somewhere darker, or on a night with no Moon. Do you count more?

Why it works: Lights from towns hide the faint stars. Counting stars in a tube is how scientists and families everywhere measure how dark their sky is.

Week 4: Launch a balloon rocket

You need: a balloon, a long string, a drinking straw, tape, two chairs.

  1. Thread the string through the straw and tie it tight between two chairs across the room.
  2. Blow up the balloon and hold its neck shut. Don't tie it.
  3. Tape the balloon under the straw, then let go.
  4. Try a bigger breath, or a longer balloon. Which goes farthest?

Why it works: Air rushes out of the back and pushes the balloon forward. Real rockets work the same way: they push hot gas out of the back, which pushes them up.

Little ones: Balloons are a choking danger for under-eights: a grown-up blows it up and holds it, and pieces of a popped balloon go straight in the bin.

Every month
