It s the end of this first season of Crash Course Kids and we ve learned so many things. In this episode, Sabrina takes us on a tour of some of the ideas we ve talked about and how they fit into our lives. Also, what all of these ideas mean for our future.

So, we ve built a lot of things over the last year and we ve become awesome engineers in the process. But now it s time for a real challenge. Let s build a city! That s right, you heard me! In this episode, Sabrina shows us what we need to think about when we start engineering something as huge and full of problems as a city! ///Standards Used in This Video/// 3-5-ETS1-1.

We ve already talked about how the Earth is divided into four spheres (The Hydrosphere, the Biosphere, the Geosphere, and the Atmosphere). But, how do these different spheres interact with each other? In this episode of Crash Course Kids, Sabrina chats with us about how two of the spheres do, in fact, work together. This first series is based on 5th-grade science. We re super excited and hope you enjoy Crash Course Kids! ///Standards Used in This Video/// 5-ESS2-1.

So, how do we go about being engineers? In this episode of Crash Course Kids, Sabrina talks to us about the Engineering Process and why we should do things in order, as well as many of the questions we should ask along the way. This first series is based on 5th-grade science. We re super excited and hope you enjoy Crash Course Kids! ///Standards Used in This Video/// 3-5-ETS1-1.

Variables: What are they? In the case of engineering, a variable is a condition or value that can change. Sometimes we control a variable, and sometimes we don t. In this episode of Crash Course Kids, Sabrina chats to us about how variables affect our choices as engineers. ///Standards Used in This Video/// 3-5-ETS1-3.

So you know what a star is, right? Well, if you don t, you should. We ve talked about that big one in the sky a few times: The Sun! But there are a lot of bright dots in the night sky and not all of them are stars. Today, let s play a game of "Star or Not a Star" to learn a little more about everything that s up there. This first series is based on 5th-grade science. We re super excited and hope you enjoy Crash Course Kids! ///Standards Used in This Video/// 5-ESS1-1.

Let s say you re looking for a specific constellation in the sky, but can t find it. That could be because you re on the wrong part of the planet to see it. In this episode of Crash Course Kids, Sabrina talks about how the Earth s rotation and axis can affect what we see in the night sky. ///Standards Used in This Video/// 5-ESS1-2.

Hey... what s matter? No no no, not what s THE matter. What s MATTER? In this episode of Crash Course Kids, Sabrina talks about what matter is and the three states of matter: Solid, Liquid, and Gas. She also does a quick experiment that you can do at home to prove that air is matter. This first series is based on 5th-grade science.

So, if gravity pulls everything down, then why don t things on the bottom of the Earth get pulled down into space? In this episode of Crash Course Kids, Sabrina talks about gravity and explains that when we talk about gravity pulling things down, what we really mean is gravity is pulling things TOWARD the Earth. Really, it s all about attraction. This first series is based on 5th-grade science. We re super excited and hope you enjoy Crash Course Kids! ///Standards Used in This Video/// 5-PS2-1.

Have you ever heard the phrase, "You look like a Million Bucks?" Well, you do... but you also look like a million particles. In this episode, Sabrina talks to us about matter and particles and that all matter is made up of particles. Also, she shows us how matter can change states from a solid to a liquid, a liquid to a gas, a gas to a solid, or a liquid to a solid. This first series is based on 5th-grade science.

Every hear of "Sol"? Sure you have! It s our Sun! It sits at the center of our 8-planet solar system, providing us with heat and light. But how does that energy get to us?

Remember pre-school? If not, IT WAS SO MUCH EASIER! But when you were stacking blocks and figuring out which block went into which shaped hole, you were learning about properties.
