Series: Crash Course Kids
Playing with LEGOS is fun. But, they can also teach us something about matter.
The world changes. It really does! But sometimes it changes so slowly that we don't notice it. Other times it changes REALLY FAST!!!
Air resistance! It's a thing! In this episode of Crash Course Kids, Sabrina does her own Astronaut Experiment to show us how we can prove it!
What are air currents? Air currents are like rivers of wind caused by areas of high and low pressure.The air above the land is warmer and less dense, so it rises. The air over the water is cooler and heavier. The cool air rushes in toward the low-pressure zone over the land, forming a lovely sea breeze. But what about jet streams? Show Less
So, what's the difference between "weather" and "severe weather"? Is it just how hard the wind is blowing? Is it just thunder and lighting? Well, it can be some or all of those things.
Why is my weather app sometimes wrong? Well it has a lot to do with wind. Jet Streams, air cells, the shape and movement of the Earth... there are a lot of things that make weather a little unpredictable.
