What's Matter? - Crash Course Kids #3.1

Hey... what's matter?

No no no, not what's THE matter. What's MATTER? In this episode of Crash Course Kids, Sabrina talks about what matter is and the three states of matter: Solid, Liquid, and Gas. She also does a quick experiment that you can do at home to prove that air is matter.

Particulate Nature of Matter (online lab)

In this interactive activity from ChemThink, learn about solids, liquids, and gases at an atomic level. Investigate how the behavior and interaction of atoms and molecules account for the states of matter. Important terms such as elements, molecules, compounds, and mixtures are also reviewed.

States of Matter - Solid, Liquid & Gas

Everything that has weight and occupies space is called matter. All matter is made from particles called atoms and molecules.

This matter can be classified into three states:-

Solid -- The molecules of solids are tightly packed, usually in a regular pattern. Solids do not flow, since their molecules are strongly attracted to each other.

Liquid -- Molecules in liquids are close together but not necessarily touching each other. There is no pattern as they randomly move about in all directions.

Gas -- Gases are made up of very loosely packed molecules that are largely spread out moving all over the flask.

Watch this video and understand about states of matter with the help of this animated learning module for kids.

How heavy is air? - Dan Quinn

Too often we think of air as empty space — but compared to a vacuum, air is actually pretty heavy. So, just how heavy is it? And if it's so heavy, why doesn't it crush us? Dan Quinn describes the fundamentals of air pressure and explains how it affects our bodies, the weather and the universe at large.
