Teach Engineering: Penny Perfect Properties (Solid Liquid Interactions)
Students investigate the property dependence between liquid and solid interfaces and determine observable differences in how liquids react to different solid surfaces. They compare copper pennies and plastic "coins" as the two test...

Bbc: Gcse Bitesize: Why Do Scientists Think That Light and Sound Are Waves?
Light travels as transverse waves and can travel through a vacuum. Sound travels as longitudinal waves and needs to travel through a solid, liquid or gas. Read about the properties of light and of sound, and learn the differences between...
CK-12 Foundation
Ck 12: Chemistry Simulation: States of Matter
[Free Registration/Login Required] Compare three states of matter: solid, liquid, and gas.
Fact Monster
Fact Monster: Adhesion and Cohesion
The forces of adhesion and cohesion are compared and contrasted. Various phenomena which can be explained by such forces are identified and discussed.
