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...

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....

Little learners experiment with sunlight and map out how light travels. Using a mirror and slotted card, they find out about items that can reflect or absorb the light. They experiment with a variety of materials to find out how light...

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...

STEM scholars investigate sound attenuation by conducting an experiment in which they compare the farthest distance that they can hear a sound with and without ear protection.

Raise the energy level of your physical science class with this exciting hands-on activity. Applying their knowledge of kinetic and potential energy and Newton's laws of motion, young engineers use foam tubing and marbles to create...

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...

A fuel cell is where the jailer keeps gas guzzlers. Scholars review chemical reactions, chemical bonds, and chemical structure in order to apply these concepts. Participants construct fuel cell kits, using electrolysis to run the car and...

Although their name makes them sound dangerous or toxic, carboxylic acids are found throughout nature in things such as citric acid, vinegar, and even in your DNA. Through detailed readings, discussions, and answering questions...

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...

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

Bring the ocean floor to life! Earth science scholars discover the process of deep sea mapping in the third installment in a series of five lessons about ocean exploration. The teacher's guide includes helpful resources, worksheets, and...
