Physics is like music—practice makes perfect! Challenge your class using an interactive that builds harmonic skills. The engaging lesson from a playlist exploring sounds and waves revolves around wave behavior in closed-end air columns....

Ever wonder what really goes on inside a clarinet? Show your young scientists the physics of open-end air columns through an easy-to-use interactive. Learners examine the features of standing waves and calculate frequency and length in a...

While scientists have identified seven states of matter, these puzzles cover the most common three. Scholars match the properties, particle motion, and particle picture to each type of matter. Three Sudoku-style puzzles review the data...

We can't see most gases and we can't see things at the molecular level — but that's about to change! A simulation shows pupils the activity of molecules in a gas. The simulation allows scholars to vary the volume, heat, and...

Do solids, liquids, and gases even matter? Scholars match the state of matter to its particle picture, size and shape description, and description of the arrangement of the particles. Once they complete that activity, they complete a...

Alkanes contain only single bonds and have no functional groups. Scholars match the properties of six alkanes in a series of four puzzles. Problem solving and logic help cement the concepts with repetition.

Twenty-four questions about matter, the states of matter and the properties of matter make up this interactive online worksheet. Your class will determine the volume of water, the shape of water and the shapes of matter.

In 1897, J.J. Thomson discovered the electron, the first subatomic particle proven to exist. Scholars review their understanding of electrons, protons, and neutrons as they work through the puzzles. Each puzzle connects two or three...
