In this Unit we will cover: The Physics of Sound
Project: Creating a Frisbee Harp
The Materials we used were: -Frisbee - Elastic cord - Eye screws - Paper Note: We used small square pieces of paper to label each the note produced by each string
So we basically created a harp by pulling plastic chords over the lip of a frisbee. We secured the string by attatching one end of it to the middle of the frisbee, and the other end over the lip of the frisbee.
Unit 1 - Write the Unit Title here
Then we reealized we needed to somehow change the pitch of the sound the strings produced when they were plucked
Cool Physics ;)
1. So. . . we attatched the eye screws to the lip of the frisbee 2. Then wetook off the end of the string attatched to the lip of the frisbee 3. Last, we reattatched the string to the eye of the screws
We were then able to change the tension of the string by turning the eye screws, allowing us to produce different pitches!!!
