Homework Help: Help me decide with a mid range physic project

  1. Dec 8, 2011 #1
    1. The problem statement, all variables and given/known data
    Hi guys. Recently, my physics' teacher told my class to make an experiment from any of the themes which are covered in the period. I need some ideas in which I can make something, somewhat good and not easy looking, but at the same time not very budget consuming.

    2. Relevant equations

    Themes covered in my class:
    Simple Harmonic Movement
    Mechanical Fluids
    Temperature; thermodynamics.

    In previous courses, people have done the following:

    - Ram water pump

    - Hydraulic Arm.

    - Submarine.

    3. The attempt at a solution

    What I have tried proposing to no avail:

    - Pascal Tube,

    - Hydraulic elevator using Pascal's principle.

    What he wants, and will give lots of extra points to the group who deliver:


    Any ideas? I am not living in the U.S., and I have a very limited access to labs, is there a not so expensive way to do a good, somewhat-complex looking project?

    I appreciate a lot your great help!

    I think it would be pretty cool if you were to get a 5mW laser (pretty cheap online, you can find them for < 10 bucks), and use it to make a hologram. Now that I think about it, I'm sure that there is a kit online that would make it pretty easy for you to do (I don't know if that's allowed).

    Hopefully this falls under the waves category of your possible choices.

    I googled how to make a hologram and got this link,

    and even though it will be pretty easy to do, the physics behind it can be pretty in depth no pun intended.


    Just a thought :smile:

    Thanks man! I'll give it a shot! Let's see what the teacher thinks about it. :D

    Just asked the teacher... He said that it is not part of the class :(

    Bummer. Yeah, I was wondering if it would be. I don't understand why it couldn't be a part of waves. Unless your class only did standing waves or something like that.

    It's vexing that you don't have access to labs, what is the teacher expecting you to do, go to a grocery store and get materials? Bah.

    Anyway, how about you analyze a non-linear pendulum - say an inverted pendulum. It's got some pretty interesting chaotic properties.

    Or, if that's too high level, how about the behavior of standing waves on a weighted wire. That could be fairly easy to implement, get some wire from a home improvement store, add weights to one end, analyze.

    Hehehe. I'll ask the teacher that! Hopes he does not find it very simple :s.
