facts for kids. Sound Facts. Learn some interesting facts about sound that you might not have known. Understand how sound waves come from vibrations and how your ears give you the ability to hear them. Find out what the speed of sound is, how sound relates to music, the meaning of acoustics and much more.


Physics of Light and Sound for Kids. Physics is a specific area of study in the field of science that focuses on the makeup and properties of both energy and matter, as well as how the two interact together. Some of the forms of matter and energy that are covered in physics include electricity, radiation, atoms and heat. ...


In the 19th century, scientists developed wave models to visualize how sound waves moved. They understood that sound is a series of compressed air, characterized by sound molecules close together, followed by rarefied air, in which the molecules are farther apart. Waves that follow this pattern are called longitudinal waves.


There are many properties that scientists use to describe waves. They include amplitude, frequency, period, wavelength, speed, and phase. Each of these properties is described in more detail below. Graphing a Wave When drawing a wave or looking at a wave on a graph, we draw the wave as a snapshot in time.


Sound is like this vibration when it moves through objects. A purring cat is also another excellent way to feel sound at work. Sound Check; lightning makes the way for us to hear thunder. A bolt of lightning will heat up air particles very quickly. These particles are then pushed outwards, making a huge sound wave better known as, thunder.


4 Groovy Activities to Teach about Vibration and Sound Energy Most STEMists learn to appreciate vibrations as an infant when they hear their first lullaby. And, many learn to love singing children’s songs with the accompaniment of maracas, drums and triangles in preschool and elementary school.
