In this episode of Crash Course Kids, Sabrina talks about the way energy moves, or flows, through an ecosystem and how that movement forms Food Chains!

FEED ME! In this episode of Crash Course Kids, Sabrina has a chat with us about what living things eat to get energy. What makes something an omnivore, or a carnivore, or an herbivore? And how do plants fit in to all of this? Find the answers in this engaging video.

This awesome science video explores how engineers run trials to identify failure points and then design ways to fix those failure points so that they come up with a viable solution to the problem they are working on.

We know that if we take an animal out of its habitat, it will have a difficult time surviving. We also know that there's a lot more going on in ecosystems than just temperature. In fact, there are so many elements in ecosystems, that if just one leaves or gets out of whack, it can be terrible for the whole thing. This video examines how Spider Monkeys are a vital component of a rain forest habitat and what would happen if they weren't part of the ecosystem.

In this episode of Crash Course Kids, Sabrina talks about two of the four spheres that make up our planet; The Geosphere and the Biosphere. What's in these spheres? How do they affect us? How do they fit into the puzzle that is Earth? Check out the video to find out!

This is the second part of the two part tale of the puzzle that is Earth. In this episode, Sabrina talks about the Hydrosphere and the Atmosphere and what is contained in each one.

So, how are people fixing their water problems? In this episode of Crash Course Kids, Sabrina talks about a few different examples how some freshwater sources were good, then bad, then made good again. Also, Sabrina talks about parasites, fish, and dams!

This awesome science video explores how engineers develop solutions to the problems they are working on.

In this first episode of Crash Course Kids' Life Science: Ecosystems and Flow of Energy videos, Sabrina takes a look at why all living things need to eat. Plus, she shows you a way to investigate why all living things need to eat.

Water travels... a lot. In fact, the water cycle is amazing and takes water all over the planet by using evaporation, condensation, and precipitation. In this episode of Crash Course Kids, Sabrina shows us how the water cycle works and how you can create a mini water cycle right in your own kitchen!

Do you know how many people have been to the moon? Only 12! Part of the reason it's so few is because of how difficult it is to escape Earth and get into space in the first place. In this episode of Crash Course Kids, Sabrina talks about gravity, escape velocity, and how gravity works between two objects.

In this episode of Crash Course Kids, Sabrina talks about all the different mixtures, solutions, and ants that can be at a picnic.

What happens to a single ecosystem when the amount of freshwater available in it changes? Not really much good. In this episode of Crash Course Kids, Sabrina talks about ecosystems and how one small change can lead to a cascade effect in the entire ecosystem.

How would a Polar Bear do if you put it in the desert? Not well. But why? Why can't anything live anywhere? Well, this has to do with Habitats and how animals (including humans) are suited for living in one place over another. In this episode, Sabrina talks about how these Habitats form Food Webs and how those Food Webs help us understand a lot about the world.

In this episode of Crash Course Kids, Sabrina talks about how humans get the resources we need to survive, even though those resources may come from a long way away.

In this episode of Crash Course Kids, Sabrina talks about what properties are and how we can measure them to tell us more about an object.

Playing with LEGOS is fun. But, they can also teach us something about matter. In this episode of Crash Course Kids, Sabrina chats about chemical reactions and the Conservation of Matter.

One interesting thing about the energy we get from the sun is that it's not absorbed the same way by different materials. In this episode of Crash Course Kids, Sabrina chats about how the properties of land and water differ enough for absorption and reflection.

If you look out your window, you'll probably notice a bunch of things; houses, streets... hopefully a tree. But beyond that you'll see things like mountains, rivers, volcanoes... well, hopefully not a volcano. These are landforms and they come in different varieties. In this episode, Sabrina chats about how things like mountains, volcanoes, and plateaus come into being.

This awesome science video explores using the engineering process to build a city, while considering all the the variables.
