He stuffed a tea towel into the container assuming it would absorb most of the sound.

HOORAY for Science Sparks. In the Making Sound Waves activity, students model the function of the eardrum using a bowl covered in parchment or wax paper with loose sugar, salt, or colored sprinkles on top. Scissors or sharp knife to cut the bottle. When objects vibrate, they transfer energy in the form of sound waves. Looking for great end-of-year student gifts? Each Video Lesson asks a science question, teaches students about the relevant science, and guides students in a hands-on experiment that will help them answer the question. Today we're doing some science experiments with sound. Record the noise you hear outside with an MP3 device. This is volume. [E] Find out if the frequency of a sound wave affects the speed of that sound wave. All of those will work just make sure you are consistent as far as method and period of time. Balloons are a staple of STEM for teaching kids about static energy, but this sound experiment puts these handy party supplies to use to discuss another kind of energy! It was once thought that the ocean was a silent place. Help your child fill each jar with varying amounts of water. http://theeducatorsspinonit.blogspot.com/2013/07/music-ideas-for-summer-fun-after-school.html.

Making sounds with this paper device, kids will observe the changes in sound based on the size of the vibrations, similar to the way the rubber band on the harmonica works. Students will use the data collected to create and build 2 and 3 dimensional topographical maps and graphs. Then, read the results on the audio meters on your software package to find out which material absorbed the most sound and kept it from coming out in the hall. You could blindfold them and spin them around, or you could have them ride a merry-go-round, or twist them around in a swing, and let the swing turn back around to its normal position. Through this service youll be first to know about the newest free experiments, science news and special offers. See how this family experimented with a rubber band guitar and even added a guitar neck from a cardboard tube. Skill Summary Legend (Opens a . These sounds are analyzed qualitatively (verbal descriptions) and then quantitatively (measuring frequency, wavelength, and amplitude) using a microphone, a hydrophone, and a computer with a sound analysis program.
