Cut the tape into strips 30mm long: 3 strips about 2.25mm wide, and 7 narrow strips about 1.5mm wide.
|
Apply tape strips in the numbered order shown here. Note that strips 3, 4, 5, 15, and 16 are wider strips. Strips 3, 4, and 5 are all cut from one wide strip. Strips 10, 11, and 12 are all cut from one narrow strip.

Use your dihedral gauges to set the angle at the nose at 165°, and at mid-wing 155°.
To throw your world record plane, hold it where the most layers meet (at the thickest part). Keep the wings level. Strive for smooth acceleration.
Get the plane flying straight, and then work up to a fast throw. For turns at regular gliding speeds, you’ll adjust the trailing edge of the plane normally. See “The Flight Stuff” below for tips on adjusting your plane’s control surfaces.
But keep in mind that the faster this plane flies, the closer to the nose your adjustments will be made. At our highest throwing speeds, if the plane veered right on launch, I would bend the leading edge on the left down a little, at the nose.

1. Select Sound (middle). 2. Make a wave with the highest pitched tone. 3. Drag tape & scope tools to measure its wavelength.
5. Make a wave with the Lowest pitched tone & Measure its wavelength.
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"
Set damping --> none, select "Slow Motion", "No End" & "Oscillate"
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).
(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)
Thread the paperclip through two holes in the tinfoil. Tiny bit of clay holds it in place. You must include at least three washers.

Important!!! Test your parachute in a graduated cylinder first!! 1st Do a dry run, and then fill with water, test again, & dump the water.
Playground Challenge
Make a Ramp (no friction) which includes the following;
1. Loop (top height must be on grid line #8),
2. Three square with low impact landing (friction from impact cannot exceed 25%)
