1) Check out the following youtube video:
Go outside and listen to the cars as they pass. Notice the shift in the frequency/pitch of the sound as a car goes from approaching you to leaving you behind.
You are NOT listening for how the cars get louder as they get nearer and then less loud as they go off into the distance. You are listening for a change in pitch
(like in the video).
2) Hang a spoon from a piece of string in such a way that it is free to swing without hitting anything. You are going to time how long it takes for the spoon to
swing back and forth ten times under the following conditions: One spoon hanging from a piece of string 6 feet long and initially swinging very high (keeping
the string tight you simply let it go from a fairly high position). One spoon hanging from a piece of string 6 feet long and initially swinging fairly low. One
spoon hanging from a piece of string 3 feet long and initially swinging very high. One spoon hanging from a piece of string 3 feet long and initially swinging
fairly low. Two spoons hanging from a piece of string 6 feet long and initially swinging very high. Two spoons hanging from a piece of string 6 feet long and
initially swinging fairly low.
3) Now get yourself at least five pieces of different colored paper. One at a time, stare at one of the pieces of paper for 60 seconds and then stare at a white
piece of paper or white wall. What do you see? Why? Your Lab Report should include of a statement of what you expected to happen (the hypothesis), a
detailed descriiption of what you did, and a listing of your observations and conclusions.
