Drop Box Project Guidelines

Develop an experiment to test the effects of microgravity 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 the weight of an object in micro-gravity?
 * Ask a Question:**

//(Try looking at pages 126-129, section 6.2 of your text book!)// microgravity is when an object can reach near weightless conditions; this is possible when an object is in free fall and the earth is not acting upon it in any form. In order to reach a weightless state, scientists use a drop tower. This is where they can let and object fall freely for an extended amount of time. An object can also reach weightlessness in a special aircraft which fly parabolic flights, as well as in sounding rockets.
 * Do Background Research:**

An object's apparent weight in microgravity will move closer to a weightless state.
 * Construct a Hypothesis:**

1.measure Alex's normal weight 2.put Alex and video camera in elevator 3.push up button and go up 4.record scale in upward motion 5.push down and go down 6.record scale in downward motion 7.transfer onto computer 8.analyze info and make conclusions
 * Test Your Hypothesis by Doing an Experiment:**

In our elevator experiment we used a scale to measure apparent weight while moving in a slowly accelerating upward motion and a slowly accelerating downward motion. As we began moving upward in the elevator, the weight on the scale experienced a sudden jump, then slowly evened out until the elevator reached the third floor. The descending trip yielded a decrease in weight as the elevator accelerated downward. With these tests, we can conclude that and object exposed to an upward motion will increase in weight, while an object exposed to a downward motion, or micro-gravity, will experience a decrease in weight.
 * Analyze Your Data and Draw a Conclusion:**
