All About Tornados
Tornadoes, nearly three-quarters of which occur within the U.S., are unpredictable and can cause massive damage. New tools and data are helping scientists learn more about when they might form and what paths they might take.

What is Climate Change?
Climate Change is a real and serious issue. In this video Bill Nye, the Science Guy, explains what causes climate change, how it affects our planet, why we need to act promptly to mitigate its effects, and how each of us can contribute to a solution.

Clouds and Weather
This video, featuring original stop-motion animation, is a fun way for children to learn about different types of clouds and their relationship to weather. It encourages young children to develop their powers of observation, an important component of the scientific method. After seeing the video, children can watch for cloud patterns in the sky and observe what these clouds signal about weather changes.

The Water Cycle
It's easy to take water for granted. After all, you just turn a faucet and it pours right out. But how does it get to our faucet? We'll explore the water cycle from rain to your drain. And did you know that space is full of water? It's one of the most common features of the universe. We'll also look at all the important things our bodies do with water -- and how that's a cycle too. Caution: this episode may make you very thirsty. (21 minutes)
Water, water everywhere -- but how does it get there?
Thunder, lightning and tornadoes
There are some basic ingredients needed to make thunderstorms and tornadoes. We'll find out what they are – and how to observe these powerful and amazing storms safely. Plus: A weather-related mystery sound! (14 minutes)
Thunder, lightning and tornadoes: Where do they come from?
Predicting the weather
There's all sorts of weather happening right now around the world. Rain, sun, wind, snow... you name it, somewhere it's happening. It may seem hard to keep track of it all, but scientists have it figured out. We'll find out how they collect data on weather around the globe and turn it into a forecast. We'll also find out where wind comes from and test our ears with the mystery sound! (24 minutes)
How do meteorologists predict the weather?
From a distance, snowflakes may all look the same, but they are not. In fact, there are lots of different shapes of snowflakes -- not just those classic shapes you might try to replicate with paper cut-outs. Dr. Ken Libbrecht answers all of our snowflake questions: How are snowflakes made? Why are they different shapes? How is it that they're all unique? And how does a scientist who lives in southern California study snow? And, he also lets us in on his brush with a couple Arendelle princesses. Music in this episode by Podington Bear. (12 minutes)
Why are no two snowflakes the same?
