A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Since light travels faster than sound, some people may appear bright until you hear them speak. The presentation covers what sound is, how fast it travels in various mediums, properties of sound, hearing, and the parts of the human...

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...

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....

What can your class tell about a wave just by looking at it? Using a simulation, physics pupils work through a series of case studies to determine the effects of speed, frequency, and density on waves. Part of a larger playlist on waves...

Learning about waves can have its ups and downs, but a demo-packed tool kit has the class "standing" for more! Learners gain experience with several different wave types, organizing observations and data, and wave...

Begin your states of matter lessons with a demonstration designed to introduce the concept that all matter has properties. Reinforce this concept through vocabulary exploration, and the creation of atom models; salt, water, and carbon...

What is a physicist's favorite part of sports? Doing the wave. The presentation covers longitudinal, transverse, surface, and standing waves. It includes in-depth information on frequency, wavelength, period, amplitude, reflection,...

What is the net effect when two waves interfere with each other? The lesson plan answers this question by helping the class visualize waves through graphing. Pupils graph individual waves and determine the effect of the interference...

Section 9 of the 12 linked Saxon Math sections introduces the young algebrist to graphing periodic functions, creating graphs from quadratic roots, working with inequalities, and rational equations. Common among all the lessons is the...

Sugar cubes, collide! Groups design protection systems using bubble wrap to protect sugar cubes from being destroyed by falling batteries in the STEM lesson. They consider how the experiment relates to collisions in real-world...

Combine the study of art, music, and history with an activity that asks kids to craft rattles out of slabs of clay.

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...
