Josh Kurz breaks macaroni salad down to its smallest chemical components. [3:14]

One way scientists talk about matter or substance-that is, the stuff in the world-is in terms of pure substances and mixtures. Pure substances are substances that contain only one kind of molecule. Water with nothing else in it is a pure...

Work samples, phenomena, assessment templates, and videos that directly address standard MS-PS1-5: conservation of atoms in reactions.

Can you defy the force of gravity by making liquid in a toy rise and fall without turning it over? This experiment will show you how to use hand boiler that uses temperature and pressure to move liquid into the top chamber.

Investigate the properties of a strange substance which acts like a liquid and a solid. This simple experiment can be done with corn starch and water.
