Develop an experiment to test the effects of micro-gravity and present your findings to the class.
 * Drop Box Objectives:**

Use the scientific process as the basis for your project…
 * Drop Box Guidelines:**

What happens to an egg that's suspended from elastics, in micro gravity?
 * Ask a Question:**

http://en.allexperts.com/q/Physics-1358/Egg-Drop-2.htm The physics of the situation boils down to the fact that the egg will have a certain amount of kinetic energy when it gets to the ground (KE = mass x acceleration-of-gravity x height). This energy must be dissipated by the work the egg does when it exerts a force on its padding over some distance (Work = force x distance). The longer the distance, the less force needed. Since the force is exerted on the egg from the time your box first hits the ground until the egg comes to a stop, you want the force to be exerted over the maximum distance possible, and you want the force to work over the entire distance.
 * Do Background Research:**

Our hypothesis is that the elastics will absorb the impact of the fall, and the egg will not break. As the box drops, the egg will move up due to gravity.
 * Construct a Hypothesis:**

Egg Drawing Supplies Needed: Egg, Styrofoam ball, rubber bands (3 Large, or 6 small tied together), tape, gauze pads. First, we will put an egg in a hollowed styrofoam ball, with gauze pads surrounding the egg if needed. Then, we attach elastic bands to the plastic egg, on the top and both sides like in the drawing, with masking tape. We may also change the position of the bands on the egg as we do our experiment. Then, we attach the bands to the drop box. The bands clip into the box, and through the top hole of the box, and tie together. We will place the camera outside of the box so that it will not touch the bands or the egg. From here, we get our results.
 * Test Your Hypothesis by Doing an Experiment:**

 * Analyze Your Data and Draw a Conclusion:**

If gravity is acting upon everything in the box then everything is going to fall at the same rate and appear is if its not moving. In our hypothesis we said that the bands were going to absorb the impact, which would keep the egg from breaking, which it did. The egg did not appear to move up as the box moved down because of the gravity acting on the entire system. In the video you can see the egg bouncing around on impact. The tension in the rubber bands allowed the egg to bounce around without breaking. After the impact, the egg returns to its original position in the box. Regarding impulse, when we increased the time, the force decreased (Ft=change in momentum).


 * Communicate Your Results:**

Brag sheet! After completing the project each group member will write a one page summation of their roll and responsibilities during the project. Include your name and class period at the top. Discuss what you contributed to the group and what you discovered. If you where to do this project again, what could you improve?

HaVe FuN!!!! _ Try to pick a question that the group is genuinely interested in answering. Listen to instructions and stay on task. The fewer reminders you hear from me the happier you will be!
