Measuring Hearing Impairment

Pupils study hearing and are able to differentiate between different sound waves.  In this sound wave lesson students develop a cause and effect model that shows the parts of the ear. 

Beautiful music doesn't just write itself, but if you ever feel bad about procrastinating, remember that Mozart wrote the overture to Don Giovanni the morning it premiered. Introduce young scientists to the elements of sound including...

In this Benford's Law learning exercise, high schoolers read about the first digit frequency of numbers. Learners solve 3 problems about sunspot numbers, solar wind magnetism and the depth of the latest earthquakes by using on line sites...

Molar mass, gram molecular mass, and gram formula mass essentially mean the same thing. The brief video, part of the Socratica "Chemistry Lessons" playlist, explains how to solve these problems. It walks through the required tools, the...

Scientists and engineers in every field use scientific notation. The Socratica video explains what scientific notation is and why people use it. Then, it offers examples of how to convert a number into and out of scientific notation....

Generally, Lorentz transformations require high level math skills, but conceptual understanding can slip just beyond the grasp of many. Using a story and graph about the time and motion of people and cats, viewers of a short video can...

Young scientists explore hearing through multiple experiments, demonstrations, and activities. They focus on the changes in hearing over a lifetime, how we can determine where a sound is coming from, and the ability to filter noises.

Young scholars examine the effects of hearing loss. For this lesson on physical disabilities, students survey five older adults on hearing impairments. Young scholars pool their data and compare their results with the results from other...

The human body can regulate itself through sweating and resting. Learners with visual impairments discuss how the body changes when it is under stress and what it does to regulate itself. To start, kids use talking thermometers to take...

Explore how sound travels as waves with a straightforward lesson that explains the basics of waves in relation to sound. The presentation considers sound waves in both open and closed pipes and shows how to calculate wavelength and...
