A Pan Flute. Shorter pipes produce higher frequency sound waves and a higher pitch. Good activity when you teach a unit on sound. The link gives you exact measurements to make notes in a true scale so you can play songs. The shortest straw must be exactly half the length of the longest straw.
Tesla said it. Einstein Agreed. Science proved it. It is a known fact that everything—including our own bodies—is made up of energy vibrating at different frequencies. That being said, can sound frequencies affect us? Most music worldwide has been tuned to A=440 Hz however, studies regarding the vibratory nature of the universe indicate that this pitch is disharmonious with the natural resonance of nature A=432 Hz and may generate negative effects on human behaviour and consciousness.
Here is an entire unit on sound complete with lesson plans and 4 activitie for students to explore concepts about sound such as: frequency, pitch, sound waves. Common Core Standards also included. Objectives: The students determine what makes a sound loud or soft, conclude that sound travels in waves, demonstrate the effect that length has on the sound of a vibrating material, demonstrate how frequency affects the pitch of sound, and create an instrument that produces sound.
Outdoor chimes, My father built these for me. The stand is made out of PVC pipe and the chimes are electrical conduit. Each chime is made in graduated lengths for different sound pitch. by Corinne Carr
Water Play, Music Play & Children: A Natural Combination at Children's Play Music. This is amazing. Spend six minutes and watch the video. Then, grab the kids and a big tub of water and get ready for music, play, and the science of noise! PS - I am totally making a packing tape drum!!
