Let knowledge of chemistry flow like water. Future scientists conduct two different experiments to investigate the properties of water. They learn about surface tension and cohesion as they see how many drops of water they can place on a...

Why do different substances have different boiling points? Through an interactive lesson, learners explore how intermolecular attractions affect boiling points. They interact with molecules through an animation and make conclusions about...

Crystal comes from a Greek word meaning ice. Activity eight in a series of 36 has class members analyzing amorphous and crystalline solids and further classifying them based on their forces. They then explore solids, learning about unit...

Due to surface tension, dew — a liquid, is spherical in shape. Learners explore the properties of liquids in activity seven in this series of 36. Beginning with its basic properties such as boiling point and moving through to surface...

Sixth in a series of 36, this lesson focuses on gases and their behavior in given situations. Learners review the states of matter and then focus on gases, specifically learning Boyle's, Charles's, Avogadro's Laws, Dalton's, and Graham's...

The Environmental Protection Agency monitors sensors to track air pollution and set clean air standards. Enthusiastic young scientists use similar sensors to gather data in their area and then apply the gas laws and conservation of...
