This awesome science video goes over how and why engineers evaluate different solutions to come up with the best solution to the problem they are working on.
Today we're going to take a hike up Mt. Kilimanjaro so we can talk about how the geosphere changes based on many different things. On the same mountain we can travel through many different habitats like rain forests, savannas, and moorlands. Let's take a walk with Sabrina and see how!
This video takes use down into the ocean to see what habitats await us there. Yep, the ocean has layers and the types of things we encounter there change the deeper we go.
Have you ever heard of the Peppered Moth? It's a great example of how living things can change because their environment has changed. And it's not just them! There used to be giant insects roaming the world, but they got smaller through time because their environments changed. In this episode of Crash Course Kids, Sabrina gives us some examples of how and why living things change because of their environments.
Plants! We absolutely depend on them. Oxygen, food, and looking super nice to boot! But, plants have a lot more going on than meets the eye. How do we know that? Investigations and Experimentations!
Did you know we can actually make diamonds in a lab? It's true! We can! In this episode of Crash Course Kids, Sabrina shows us how materials scientists have done just that and why it's so important.
So, we know what materials are, but can we make new materials? Or improve the materials we already have? In this episode of Crash Course Kids, Sabrina shows us how Material Scientists are working on these two things today.
In this episode of Crash Course Kids, Sabrina uses what she knows about properties of objects to solve the mystery of what she tripped over last night.
So, what happens to normal stuff (like water) when it goes to not so normal places? What happens if you take a glass of water to the top of Mt. Everest? Or Space? In this episode of Crash Course Kids, Sabrina shows us how matter is affected by different pressures and how that make water do some weird things.
Ever heard of Oobleck? How about Non-Newtonian fluids? Well, today Sabrina is going to show us that things can sometimes behave like a solid, and sometimes like a liquid depending on how much force is applied to them. In this episode of Crash Course Kids, we'll talk about some weird stuff that's still... normal.
This Crash Course Kids video reviews how substances can be organized into groups according to their various properties.
Do you want to be an astronaut? Would you like to someday walk on the moon? Well, you better learn a little about gravity so you can escape from Earth and head into space. In this video, Sabrina chats with us about what it takes to get to the moon!
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 awesome science video explores what the Earth's resources are and how we use them.
This awesome science video leads students through the process they could use to engineer the solution to a problem. There is a challenge to design a robot to help them solve the problem in the video.
Even an empty lunch sack is useful to science. You can examine it and come up with some traits. In this episode, Sabrina chats about things like malleability, hardness, conductivity, and magnetism.
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. In this episode of Crash Course Kids, Sabrina talks to us about what makes Severe Weather and how it interacts with the Geosphere and Biosphere.
This awesome science video explores how engineers discover solutions to their problems by identifying the parts of the solution that fail (failure points) and using that information to design better solutions that won't fail.
This awesome science video explores how engineers make a plan to test all of the variables for the problem they are seeking a solution to.
This awesome science video outlines how, as part of the engineering process, engineers identify and isolate variables and then run trials to test their solutions.
