Sound the Alarm

History Sets the Scene:The First Telephone 1875 First Sounds experimented with twangs using a technique called "harmonic telegraph“ 1875 Discovery Graham discovered sound could be heard over a wire. The sound was that of a twanging clock spring. 1876 First Voice “Mr. Watson, come here. I want to see you.” experiment with the telephone. Speaking through the instrument to his assistant. 1876 Inventions Patent for telephone filed with the United States government. 1877 Incorporation Formed the Bell Telephone company. By 1880 over 60,000 phones were in the United States. 1878 International Bell demonstrates the telephone to Queen Victoria.

Feel the Vibration Soundis caused by vibration. Sound is energy that you can hear. You may a hear a dog barking or a telephone ringing. You may hear music playing or people talking. The sounds different, but they are made in the same way. All sound is made when something vibrates, or moves quickly back and forth. What sounds are these pictures making?

How do we measure sound?

Shhh! Did You Hear That? Did You hear that?You hear a sound and turn your head. How did you do that? How did you hear a sound vibration in the air?

How You Hear You hear sounds with your ears. • Sound vibrations move through the air into your ears. • Moving from your outer ear to your inner ear, the vibrations cause the eardrum and the tiny bones in you r ear to vibrate. • The inner ear sends signals to the brain.

HowWe Hear

Dance to the MusicEnjoy a selectionof music with different beats and rhythms, and learn about pitch. Create instrumentsand use them to play at least three different pitches.

Experimenting with Sound • Students will be instructed to get with their partners for a sound experiment. • Materials Needed: • Metal Coat Hanger • String • Bowl of Water • Metal Spoon • Table • Children will test the sound-vibration that travels from the hanger and metal spoon to their ears while putting their fingers inside with the string attached. They will record what happens in their Science Journals and then other materials will be available to be tested like a muffin tin, a plastic spoon, etc. They will record their findings in a chart (Appendix )

FilamentalityMixing Technology with Sound • Students will be given the laptops and asked to search the Filamentality page set up for them. • In it, they will be asked to find certain sounds and answer questions based on the information on the directed sites. • http://www.kn.att.com/wired/fil/pages/listhearthete.html
