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...

SciShow News explains the latest climate weirdness, and why the Global Warming Hiatus wasn’t really what it sounded like. Plus, see how humans have harnessed the climbing power of the gecko!

This video is an educational program about physical and chemical changes in matter. The host uses examples such as baking cookies and a rusty bike fender to explain the concepts of physical properties of matter, chemical reactions,...

In this video, students will learn about different methods of separating substances in mixtures and solutions. They will explore physical changes in matter, the properties of mixtures and solutions, and the processes of evaporation,...

This video is a lesson on the physical changes that occur in matter as its internal energy increases. The video describes how the physical state of matter changes as it is heated, from a solid with particles in fixed positions to a...

Howcast - Check out part 63 of this walkthrough for this action RPG Deus Ex: Human Revolution and sneak through Omega Ranch to rescue Megan Reed.

The malaria vaccine was invented more than a century ago -- yet each year, hundreds of thousands of people still die from the disease. How can we improve this vital vaccine? In this informative talk, immunologist and TED Fellow Faith...

This video lecture focuses on how the volume of a gas affects its pressure. It first explains how temperature affects pressure and then delves into the example of how a fixed mass and temperature of gas stored in a piston react to...

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...

The video explains the three main states of matter, which are solids, liquids and gases, and their properties. The concept of state symbols is introduced to indicate what state chemicals or particles are in a reaction. The video also...

When a substance changes its state, heat energy is involved. This energy is used not to heat up the substance, but to separate the molecules from each other. This is known as specific latent heat. Specific latent heat is defined as the...

True Calling Grant Filmmaker: Chelsea Kanstrup It all started when Ry Williams decided to run across the country. From there he became a motivational speaker, which led to learning how to weld and working in the oil and gas industry....

Safety in science always comes first. This program demonstrates safe practices in science when conducting even the simplest of activities. Emphasis is placed on avoiding accidents to eyes, skin, clothing, and equipment. Safe practices in...

The elephant is a creature of epic proportions -- and yet, it owes its enormity to more than 1,000 trillion microscopic cells. And on the epically small end of things, there are likely millions of unicellular species, yet there are very...

Physical Science for Kids is the fun way to learn important facts about physical science and get ready for tests. Take a fascinating journey to the Super Science Station to learn about lab safety, the scientific method, atoms, molecules,...

Most people are taught that dinosaurs went extinct 66 million years ago when a giant meteor crashed into the Yucatan peninsula. I'm here to tell you that's wrong. Dinosaurs are alive and well today, and you don't have to go to Jurassic...

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 -...

The full moon might seem bigger on the horizon than when it's higher up, but when does it actually take up more space in the sky?

This video explains the relationship between energy and changes of states in matter. It discusses the different changes of state, such as melting, boiling, and condensing, and the fixed temperatures at which they occur. The concept of...

What's up with baby teeth? Do other animals have them, and what are they good for -- other than squeezing money out of the tooth fairy? We have the answers!
