How the heck do we map out a planet without oceans? NASA had to figure that out when we sent the Mariner 9 probe to Mars. There's some tricky, yet fascinating science behind all of it! In this episode of Crash Course Physics, Shini talks...

Upon viewing the The Changing Phases of Matter video series, students will be able to do the following: Explain that phases of matter, also called states of matter, are the physical forms matter can take. State the four phases of...

This video explains the concept of heat energy and its role in temperature and phase changes. The video also highlights how heat energy is responsible for phase changes, using the example of water transitioning from solid ice to liquid...

In this video, we explore the concept of heat energy and its role in warming up our hands when we rub them together. The video also highlights examples of phase changes, such as ice melting into liquid water and further heating...

If you have ever torn up a piece of paper or seen ice melt, then you have witnessed physical changes. This fascinating program helps students understand some of the different ways matter changes physically. Vivid animations also...

Upon viewing the The Water Cycle video series, students will be able to do the following: Define the water cycle as the continual movement of water between earth and the air. Explain that the water cycle consists of three processes:...

We know that the free energy change associated with a process will tell us whether it is spontaneous or not. And we also know that this depends on the change in enthalpy and the change in entropy for that process, as well as the...

In this video Paul Andersen explains how energy can enter and leave a system. The amount of energy a substance can receive through heating or lose through cooling is measured using the specific heat capacity. Phase changing energy from...

The Water Cycle part 1. Students will be able to do the following:

- Define the water cycle as the continual movement of water between earth and the
air.
- Explain that the water cycle consists of three processes:...

What are the differences between solids, liquids, and gases? In this program students will investigate real-life examples of the various phases of matter. Colorful animations illustrate how these states differ in the movement of...

In Water as a Natural Resource we are introduced to words such as habitat, ecosystem, watershed and estuary. Not only do kids learn that water exists everywhere on Earth, but that it is vital for life in plants, animals, and all other...

This program begins by defining heat of vaporization is the amount of heat that must be added or given off to vaporize one gram or kilogram of a substance and is expressed as J/g or J/kg. Through real, live footage and animation,...

Water and oil do not mix (immiscible liquids) because water is polar and grease oil is non-polar. They do not form intermolecular bonds and instead repel each other. There is a separation of oil and water layers. The denser liquid...

In this video, I explain how to use Gibbs phase rule in relation to phase diagrams; also, I work 5 examples of Gibbs phase rule.
