Eighth Grade Waves and Their Application for Information Transfer. MS-PS4-1 Students who demonstrate understanding can: Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
MS-PS4-2 Students who demonstrate understanding can: Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials. MS-PS4-3 Students who demonstrate understanding can: Integrate qualitative scientific and technical information to support the claim that digitized signals (sent as wave pulses) are a more reliable way to encode and transmit information. A wave is a disturbance involving the transfer of energy from place to place. Each wave has a repeating pattern of wavelengths, frequency, and amplitude that allows for energy or information to travel distances.
Bone conduction: Get used to the voices in your head. Bone conduction technology allows people with deafness to hear, helps tech-heads talk, and lets swimmers listen to music underwater.
Find out more. For people with some forms of hearing loss, where sound cannot take the natural path from the outer to the inner ear, bone conduction can help them get round the issue. The Bonebridge implant transmits sound waves via bone conduction directly to the inner ear where they are processed just like a natural sound. Artist Markus Kison found a haunting new use for bone conduction technology: allowing visitors to Dresden, Germany to relive the horrors of the city's WWII air raids. At a silent observation deck, visitors can look out over the city, while placing their elbows on the railing and cupping their ears to hear the screeching airplane engines and exploding bombs. Monday’s Fun: If You Put Labs In Water, They Turn Into Dachshunds! Waves. This is a set of interactive tutorials designed to teach the fundamentals of wave dynamics.
It starts with very simple wave properties and ends with an examination of nonlinear wave behavior. Sheets - create and edit spreadsheets online, for free. One account.
All of Google. Scientists have found a way to photograph people in 3D through walls using Wi-Fi. Wi-Fi can pass through walls.
This fact is easy to take for granted, yet it's the reason we can surf the web using a wireless router located in another room. But not all of that microwave radiation makes it to (or from) our phones, tablets, and laptops. Routers scatter and bounce their signal off objects, illuminating our homes and offices like invisible light bulbs. Now, German scientists have found a way to exploit this property to take holograms, or 3D photographs, of objects inside a room — from outside it. Sound wave visualised.

New Tech Could Read Books Without Opening Them. Using technology akin to X-ray vision, scientists can read closed books, identifying letters printed on stacks of paper up to nine sheets thick.
This finding could lead to office machines that can scan reams of paper at once, or help researchers scan ancient books that are too fragile to open. The researchers also said it could perhaps help spies read mail without opening envelopes. The prototype device uses terahertz radiation, the band of electromagnetic radiation between microwaves and infrared light. Sound Booth Construction. (From TeachEngineering.org.

Lesson Plans On Sound And Acoustics For Grades 4 Through 6. Acoustics is the study of the properties of sound and how sound is transmitted through space.
Engineers working on airplane design pay close attention to the acoustics of the airplane cabin in an effort to keep passengers as comfortable as possible. In this module, students develop, test, and modify designs for a quieter airplane cabin. Gravitational force on a dropped slinky. Google Docs - create and edit documents online, for free.

Modeling Earthquake Waves. An earthquake occurs when massive rock layers slide past each other. This motion makes enormous vibrations, which travel from the site of the earthquake in waves. The waves (seismic waves) travel all the way through the Earth. Seismologists can record these waves when they reach Earth’s surface using seismographs.
Earthquakes generate three kinds of waves: Compressional waves (P waves) travel the fastest. Seismograph. Seismic waves animation activity. How do P & S waves give evidence for a liquid outer core?
