Hear from a cloud, conduct some science experiments, and finally learn why the sky is blue!
1. Meet Nimbus the Cloud
The best way to learn is from an expert… and who better to teach about the sky than someone who lives there? Meet Nimbus! He and Mr. Derek talk about different types of clouds, while grounding the conversation in emotions that we all feel.
Hi From the Sky: Meet Nimbus
Hi From the Sky: Nimbus’ Silver Lining
Hi From the Sky: Nimbus and the Falling Water
Now that you’ve met a cloud, want to have one of your own? You can create a cloud on the ground with our DIY cloud in a bottle experiment! Using shaving cream, a cup, and some blue food coloring, you can observe a Nimbus of your own. He’ll even “rain” in the cup!
You’ve learned all about the sky… but how do you get there? One way is with a rocketship! Rockets enable astronauts to travel into outer space. There they can visit the moon and learn about other planets and stars.
We can build two types of rockets at home. The first one is a balloon pushed by air in a straw. The second one is an empty water bottle that’s propelled by a chemical reaction. Test out both, and send us videos of your rockets flying!
So… why is the sky blue?
It’s one of the most popular kid questions, and for a good reason. The sky is usually a beautiful shade of blue. But why?
NASA has a great answer to the question. Here’s what they say:
- Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
That’s why our sky is blue! But the sky can look different on other planets. On Mars and Venus, for example, the sky is much more orange during the day. Our sky has those colors during sunsets.
What’s your favorite look for the sky? Do you like when it rains or snows? Do you like seeing airplanes flying through the clouds? Let us know!
