1. Create the fastest wave (high tension), with a wavelength = 3.0 cm, & an amplitude = 1.25 cm,
Set damping --> none, select  "Slow Motion", "No End" & "Oscillate"

1. Select Sound (middle).  2. Make a wave with the highest pitched tone. 3.  Drag tape & scope tools to measure its wavelength. 

    Answer these question about the highest Pitch tone.
5. Make a wave with the Lowest pitched tone & Measure its wavelength. 

    Answer these question about the LOWEST pitch.

Explore Intro, & Balance Lab, then complete the Game. At least 4 out of 6 stars in all levels = A+ 
                                                                                                5 out of 6 stars for all levels = A++
                                                                                              6 out of 6 stars for all levels = A+++

Shoot/Drop a Car Horizontally (0 degrees) so that it falls for 1.75 seconds.
Tape the top and bottom of a meter stick to the wall and counter.  ​Add clothespins at an angle.  The clothespins will move, 4sure! Make readjustments each time you roll a marble.   The clothespins are like air molecules. This demonstrates how air resistance can cause terminal velocity (a.k.a. constant speed).

2. Slowest Constant Speed (Roller Coaster)
(We work in chairs at desks).  At the end we will move our projects to the counters behind our signs.
Note:  Everything fits on top of the counter.  You cannot build below the counter (like to the floor). Maximum height is the ring stand.  

3. Slowest Constant Speed (Metal Parachute)

Metal Parachute Demo (Video)
Thread the paperclip through two holes in the tinfoil.  Tiny bit of clay holds it in place.  You must include at least three washers.
Picture
Important!!! Test your parachute in a graduated cylinder first!!  1st Do a dry run, and then fill with water, test again, & dump the water.
