1. discuss closure
2. what is Numerical/Computational Physics?
3. look at spectrograms
4. clarify the assignments
5. labs

projected labs

6. microscopic surfaces (what’s outside)
   1. static friction
      1. put small plastic bins of different sizes containing different objects on an inclinable plan
      2. lift one end of the plane and measure the angle at which the bins start to move
      3. what do you observe?
7. density of materials (what’s inside)
   1. calculate the amount of water displaced by different materials
   2. investigate what Helium does to voices, flutes, speakers and balloons
   3. show what balloons do in stopping cars
      1. chart it on a camera
8. oscillation
   1. prove Hooke's law
   2. shatter a glass with sound
   3. predict the fundamental frequency of air in a tube
   4. thought experiment: how would you make a human voice?
   5. What does friction contribute to the oscillation?
   6. How does friction relate to the turbulence created in the mouthpiece of a flute?
9. deformations and failure
   1. let's break a copper wire
      1. measure how much deformation occurs before it breaks
      2. how does the wire behave as load is added?
10. hardness
    1. establish a hardness scale based on scratching surfaces
11. micro-structures (crystals vs. glass)
    1. what is the micro-structure of felt? how does it compare to fabric? or wood?
12. light, mirrors and lenses
13. conductivity: of heat, of sound, of electricity
14. media: viscosity, stretchiness
