Sound can be a difficult concept to portray because the sound waves cannot be seen or touched. Luckily, there are several at home experiments that demonstrate the properties of sound waves.
You can use a fish tank half filled with water to give a visual demonstration 
of ‘sound waves’. Water is a perfect medium to show the propagation of waves. This demonstrates how sound waves travel though the air. There are two ways to display this activity. One way is to simply press your hands onto the top of the water and allow the waves to be made by the pressure of your hand. This allows students to see how waves travel though a medium. You can also use this to point out the aspects of a wave such as frequency and amplitude. Another way to show waves is to place a speaker next to the tank and allow the sound to produce the waves. This can show that sound is a form of pressure just like your hand. Read the rest of this entry »
