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...

Learners examine the basic concepts of radio waves and magnetic fields. They study how the AM radios are built and demonstrate the concepts of amplitude and frequency.

Students investigate tsunamis and how they are caused.  For this natural disaster lesson, students discuss earthquakes, volcanoes, landslides and other causes of tsunamis.  Students conduct an experiment in which they drop...

Students identify the four types of seismic waves, their characteristics and effects. Then they predict the level of damage each wave might cause in a residential area and test their predictions against several computer animations. ...

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.

The scientific explanation of seismic waves is detailed in the introduction. A fictional scenario is also provided for your class to discuss. Pictures and handouts that are meant to be included, however, they are not accessible....

Let's talk about earthquakes .... Using the Internet, pupils research what causes earthquakes, how scientists measure them, their locations, and their effects. The resource is not only informative, but it also builds crucial...

Data can travel on light waves ... who knew!?! Pupils explore the idea of using light waves to transmit data through space. They then build their own boards that detect a specific wavelength of light.

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 study erosion and its effects on shorelines. In this erosion lesson plan, students work in an engineering team to design a seawall and submit a cost bid to their teacher. Students must determine the energy of a wave and design a...

Pairs use an online simulation to determine the epicenter and magnitude of an earthquake. Using real data about the earthquake's maximum S wave amplitudes, they then determine the magnitude. The resource provides a great career...

How can nanoparticles be used in the battle against skin cancer. Class members take on the question as they gather information about electromagnetic radiation, specifically ultraviolet radiation. Pupils learn about the mathematical...

Satellites require rockets to launch, but it doesn't take a rocket scientist to understand them. Future engineers learn about how satellites send data to Earth and how to interpret satellite images. They see how radio waves play a role...

How do you demonstrate radio transmissions? Pupils build a low-energy radio transmitter by constructing two coils from magnet wire and connecting them to audio/phone plugs. The resource provides the details on how to build the...

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...

Investigate sound waves with acoustic mirrors. Using audio software, groups make recordings of musical instruments, both with and without acoustic mirrors. They compare the recordings to see the effect of acoustic mirrors on sound...

Hedy Lamarr led a double life. Best known as an actress, Lamarr was also a brilliant inventor, responsible for the technology found in Wi-Fi, GPS, and Bluetooth. After studying primary and secondary source materials, groups conduct an...

What types of materials absorb sound? Learners explore sound waves, the decibel scale, and how different materials affect sound. Then, they use their knowledge of sound meters to complete a STEM engineering design task to build...

After investigating visible light and the electromagnetic spectrum students explain the concept that light can be considered an electromagnetic wave. They give two examples of how engineers use electromagnetic waves, and describe how...

Zero in on an interesting resource involving radar technology. Groups construct a radar sensing unit and learn to calibrate the system. Using the radar system and the Pythagorean Theorem, they calculate distances between objects.

Students experiment with a vibrating ruler and a kazoo to study the different pitches and frequencies they produce. They create both high and low pitch sound waves. They examine how engineers use sound energy when designing electronic...

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...
