Some interesting diagrams here will pique your students' interest as they discover what is actually inside the telephone that they use every day! The frequency and amplitude labels then lead to further details about sound and waves of...

What do physicists and musicians have in common? A lot more than you might think. After first viewing a slide show presentation and completing a series of skills practice worksheets on the physics of light, sound, and...

Toys are great for learning about physics. Scholars use Slinky® toys to study Newton's laws of motion and types of energy. After a little play, they then model longitudinal and transverse waves with the Slinky® toys.

Students explore sound. In this "sound" science instructional activity, students define sound and explain how sound travels. Students experiment with paper cups and string to conclude how sound travels. Students research a chosen aspect...

Students explore musical pitch. In this cross curriculum musical instruments and "sound" physics instructional activity, students identify and describe common traits of woodwind instruments. Students research "pitch" and what causes...

Young scientists investigate the scientific concepts and principles that help make common toys such as hula hoops, yo-yos, slinkies, and silly putty work. As a class, they read "Backyard Rocket Science, Served Wet" to get a look behind...

A brief set of notes opens the door to telecommunication via radio. The formula for the speed of radio waves is followed by the components of a radio. That's about all there is in this physical science PowerPoint. 

Class members discover how mathematics can quantify the behavior of light waves with the fourth installment of a seven-part series that teaches future engineers about equations related to refraction, including the equation to...

Make sound visible with an activity that provides directions for how to build a vocal visualizer meant to create light patterns. Making noise into the visualizer causes a mirror to vibrate, reflecting a laser beam, and creating...

Make music. Class members construct a simple record player using a paper cone and a pin. The resource provides a description of what is happening and why listeners can hear the sounds through the cone. 

In this physics instructional activity, students design and build a signal generator. They write a lab report and answer 4 short answer questions about their design.

Discovery of microwaves and other trivia starting this PowerPoint will help interest your class in the application and behavior of these radio waves. Great images to show real-life experiments and equipment help understanding of how the...

You can't b. cereus until you see this lesson! Young microbiologists learn to prepare deep well slides, observe two types of microorganisms, and compare and contrast their physical characteristics in this interactive and lively activity.

After reading about radio transmission, application, and the difference between AM and FM, small teams of engineers use a kit to construct an FM radio and then send and receive broadcasts. This is an ideal activity for middle school STEM...

Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and...

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.

Youngsters examine resource maps to find out which states are using solar and wind power and discuss as a class various other renewable energy sources. They use a provided data table to record pros and cons to each technology, build and...

Young scholars explore the properties of electricity. This lab shows students the need for a circuit in order to have a flow of electricity. It demonstrates Ohm's law, which relates voltage, current, and resistance.

Students design a program to make an automated vehicle perform a specific task. In this robotics lesson plan, students play the role of scientists competing to win a factory's contract. They present their algorithm to class.

The lesson is real—even if the computer code isn't. Scholars learn about pseudocode, which simulates computer code using everyday language. They write pseudocode for simple actions, then have classmates guess the action from the written...

Students examine how a community works together to protect them from fire. They work together to design a functional tool that could be helpful in fighting fires. They share their tool with the class.

Students examine the concepts of forces and motion. They work together to design protective devices for their egg rovers as they are dropped from a specific height. They record their observations and discuss.

Young scholars participate in a role play in which they use simple machines to do the work of retrieving their sibling from a tree which lost its ladder. They investigate how work is accomplished when an object moves in the direction of...

Young scholars investigate plate tectonics and their correlation with natural phenomena like earthquakes and volcanoes. They use the internet to see real-time data about earthquakes and volcanoes. Students plot latitude and longitude...
