Erklär’s mir, als wär ich 5

Das steht auf den Slides

1. Slide 1

   explain like i’m 5 🧠

   why is the sky blue?

   5 tiny steps. by the end you can explain it to a real 5-year-old.

2. Slide 2

   step 1 of 5

   sunlight looks white, but it’s every colour of the rainbow mixed together

   a prism or a rainbow just un-mixes it.

3. Slide 3

   step 2 of 5

   light travels in waves. blue has short, wiggly waves. red has long, lazy ones

   think of it like small steps vs. big strides.

4. Slide 4

   step 3 of 5

   the air is full of tiny bits: nitrogen and oxygen molecules

   way too small to see. there are trillions in every breath.

5. Slide 5

   step 4 of 5

   those tiny bits bounce short blue waves all over the sky. long red ones mostly slip past

   scientists call this scattering.

6. Slide 6

   step 5 of 5

   so wherever you look up, blue light is coming at you from every direction

   bonus: at sunset light crosses more air, the blue gets bounced away, and reds are left.

7. Slide 7

   in one sentence

   air scatters blue light more than red, so blue fills the sky
