Making Waves (Amplitude) Sounds On Strings Sounds in Tubes Air Cannon Student Experience Students investigate how the amount of energy affects the wave form. Students investigate how to create different sounds on vibrating strings. Students investigate how to create different sounds in columns of air. Students observe a pulse of air moving objects T4T Material Cords String, materials to use as mass(apply tension) Straws Cardboard drum, rubber bands Pee cup lids, plastic Big Idea The amount of energy affects the height (amplitude) of a wave. Length and tension affect sound pitch. Pitch is caused by changing frequencies & wavelengths. Vibrations in air can produce sound. Sound carries energy that can move through a medium to cause objects to move. Connection to Culminating Activity Amount of energy affects the amplitude of a wave. Loudness is perceived through the change in amplitude of a wave. Vibrating strings can produce sounds. The length of the string and tension are two factors that can affect the pitch. Air passing through a column can produce sound. Sound passes through a medium as energy (wave) and causes the ear drum to move allowing sound to be heard.
