my 9 year old asked why we have summer and winter. can you draw it so she gets it?

Why We Have Summer and Winter πŸŒβ˜€οΈ

The Big Secret: Earth is TILTED!

Earth spins around a pretend stick called an axis. That stick isn't straight up and down. It leans to one side, and it always leans the same way as Earth travels around the Sun.

    JUNE                                         DECEMBER
                                                         
          N                                            N
         /                                            /
       (🌍)    ----->       β˜€οΈ       <-----        (🌍)
       /                   SUN                     /
      S                                           S

  The top half leans                     The top half leans
  TOWARD the Sun                         AWAY from the Sun
     = SUMMER β˜€οΈ                            = WINTER ❄️
  (for the top half)                     (for the top half)

Notice the stick points the same direction in both pictures. But because Earth moved to the other side of the Sun, the top half goes from leaning toward the Sun to leaning away from it!


Why Does Leaning Toward the Sun Make It Hotter?

Reason 1: The sunlight is more concentrated πŸ”¦

    SUMMER                         WINTER
  (Sun high in sky)             (Sun low in sky)

  Sunshine squished into       Same sunshine spread out
  a SMALL spot = HOT!          over a BIG area = COOLER

Reason 2: Longer days ⏰ In summer, the Sun is up for a long time (more time to warm things up!). In winter, it gets dark early.


πŸ§ͺ Try This Together (5 minutes!)

Flashlight test:

  1. Shine a flashlight straight down at the table. See the small, bright circle? That's summer.
  2. Now tilt the flashlight so it shines at a slant. The light spreads into a big, dim oval. That's winter!

Orbit test:

  1. Put a lamp in the middle of a dark room (that's the Sun).
  2. Stick a pencil through an orange or ball and tilt it a little (that's Earth).
  3. Walk in a circle around the lamp, keeping the pencil pointed at the same wall the whole time.
  4. Watch how the top of the orange gets more light on one side of the circle and less on the other!

🀯 Bonus Fun Facts

  • It's NOT about being closer to the Sun! Earth is actually a tiny bit closer to the Sun in January!
  • When it's summer here, it's winter in Australia! The bottom half of Earth leans away when the top half leans toward the Sun. (Some kids there have Christmas at the beach! πŸ–οΈπŸŽ„)

The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
