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...

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...

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...

Do you know how transistors work? What is it about transistors that make them the building block of so many electronic items, like computer, laptops, smartphones and tablets these days? What is a transistor? The transistor is arguably...

In this video students will observe that regardless of the type of change that occurs in heating, cooling, or mixing, the total weight of matter is conserved. A hands-on demonstration helps students set-up their own activity to prove...

All particles belong to two large groups: fermions like protons and electrons make everything we consider "matter", while bosons like photons and gluons transmit the fundamental forces. And that about covers the universe: matter moving...

David Thouless, Duncan Haldane, and Michael Kosterlitz won the Nobel Prize in Physics in 2016 for discovering that even microscopic matter at the smallest scale can exhibit macroscopic properties and phases that are topological. But -...

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 around a billion years, increases in the sun’s energy output will ensure oxygen levels on Earth drop to levels that cannot sustain complex life, so we should build a giant thruster to shift the planet’s orbit.

SchoolOnline's Primary English videos are brilliant, bite-size tutorial videos delivered by examiners and skilled teachers. Ideal for ages 9-13, they cover every key skill in English Reading and Writing that students need to master in...

In this video Paul Andersen explains that entropy is simply the dispersion of matter or energy. He begins with a series of video that show the natural direction of processes. According to the second law of thermodynamics the entropy...

Tracy Slater describes two college professors—Ronna Johnson in English and Claire Schub in French—who profoundly shaped her love of literature, writing, and independent scholarship. Their deep passion for their subjects inspired her to...
