Yesterday the class did a sound experiment. We started the experiment by scratching under the table and listening to what it sounded like. Then we put our ears on the table and scratched under the table again to see if there was any difference in the sound. When we put our ear to the table the sound was louder. When we sat up straight, the sound was quieter. Then we used our fingertips and did the same thing. It was really squeaky. Then we used our knuckles and banged the table. It was loud. We discovered that sound travels ten times better through wood than through air. Then we wrote sentences from the board into our science copies.
