2.0 Experiment Background
As part of the NASA Explorer School Program, teachers at K.W. Barrett Elementary took advantage of the opportunity to participate in the Reduced Gravity Program. Our experiment, Spinning Toys: Balance and Motion in Microgravity, was designed by the students in second grade. Their prior knowledge about how gravity acts on playground toys helped them develop experiments and make predictions about how the toys might act the same or differently in a microgravity environment.
3.0 Experiment Description
A playground hoop (Hula hoop) and flying disc (Frisbee) will be required to conduct the second grade experiments on board the C-9 Reduced Gravity Jet. The six experiments will have three trials (parabolas) each. The two flyers will alternate roles. One flyer will perform the experiment with the playground hoop or flying disc while the other flyer will monitor the video camera, take occasional digital still pictures and act as a spotter/catcher for the test equipment.
Our objective after completing these experiments is to make comparisons between what we observed when performing the trials on Earth in 1-g and what we observed when performing the same trials on the Reduced Gravity Jet. Additionally, we will measure the number of revolutions of the playground hoop at 1-g compared to 0-g.
To make these comparisons. we made a baseline video of each of the experiments in 1-g. We will be using a mounted battery-powered video camera to film the trials in-flight.
Playground Hoop Experiments:
A. Flyer 1 will spin the playground hoop around the waist with hips.
B. Flyer 2 will spin the playground hoop on the arm and then stop moving the arm.
C. Flyer 1 will roll the playground hoop a short distance on the floor of the jet.
.
Flying Disc Experiments:
D. Flyer 2 will spin and toss the flying disc a short distance to the floor.
E. Flyer 1 will balance the flying disc on the head and turn around in circles.
F. Flyer 2 will drop the flying disc over the head and behind the back to catch it.
4.0 Equipment Description
One commercially made plastic playground hoop (Hula Hoop) with an outer material also made of plastic and one commercially made plastic flying disc (Frisbee) will be required to perform the proposed experiments on the Reduced Gravity Jet. We will also use a battery-powered video camera to record the trials. A battery-powered digital still camera will also be on board to take still photographs during the trials.

Special Requirements (In-flight or Ground Based)
We request a designated area for the experiment at one end of the test area of the cabin. The dimensions required for our experiments are 106” Width X 144” Length.
4.6 Free Float Requirements, Subassemblies and Handling Provisions
The playground hoop and the flying disc will be secured when not in use during the experiments. A flyer will act as a spotter to keep the toys from leaving the team’s designated area.
-
Structural Verification
For the trials, we will use a commercially made plastic playground hoop (Hula Hoop) wrapped in an outer material that is also plastic. The hoops will be made safer by opening them and eliminating the water and/or other substances inside. Tape will be used to seal the point of closure where the two ends of the hoop were attached to lower the chance of breakage during flight. A commercially made plastic flying disc (Frisbee) will be required to perform the proposed experiments on the Reduced Gravity Jet. We will also use a battery-powered digital video camera mounted on a pole to record the trials.
