Please write a description of the project you are proposing. Why do you want to take this on, and what do you hope to learn?
We will designing and building lab equipment (especially for lab practicums). We have helped kelly build experiments before and have found it to be very enjoyable. Kelly will also share our designs with the larger physics teaching community.
January 18 Thursday, a cold afternoon in lab biology.
The fan with many angles
The clock ticks tic tock as the ball rolls to its end
Here is a lab practicum for the BFPM objective. This practicum involves a frictionless track and fan cart, a stationary fan, some spring scales, and a piece of cardboard (or folded paper).
Question: The force exerted by the Fan on the Cart (fan 1) on the Cart itself is .25N (or whatever you measure) at a distance of 21cm apart, the force exerted by the stationary fan on the cart is .2N (or whatever you measure). Making no additional measurements, set up the angle of fan 1 so that the cart is stationary at a distance of 21cm (or whatever you choose) from the stationary fan.
Extra Question: The fan cart has a mass of 350g. When a 500g mass is placed on it, set the angle of fan 1 again so that it rests at 21cm (same as before) when both fans are turned on. [Note: the answer for this one will not change from the last question. If you want to make it a little more difficult you can ask what will change between the two problems. The answer is that if released from far enough it will oscillate slower before becoming stationary at 21cm.]
Extra Question 2: Repeat the first problem but with a slight incline to the track.
SETUP:
To set up, firmly attach the cardboard to the front of the fan cart.
Then set up the stationary fan on the end of the track, facing the cardboard side of the fan cart.
After that use a spring scale to measure the force of the fan on the cart on the cart at HIGH. Next, turn on the stationary fan and use the spring scale to measure the force of the stationary fan on the fan cart. Pick a distance between the two fans that ensures the the stationary fan is exerting more force on the cart than the fan on the card is exerting on the cart.
All set up!

What is your proposed outcome? How will you be able to demonstrate successful completion of this Project?
To have lots of nice lab equipment and experiments constructed.
