 * THE STUDY OF HOW LONG IT TAKES HELIUM TO LIFT DIFFERENT OBJECTS**


 * ABSTRACT:**

The purpose of this study is to explain how long it takes for a balloon inflated with helium to reach the ceiling of our classroom with different objects tied to it. Helium is a light gas so it floats into our atmosphere which it why it’s used in balloons and blimps. A small variety of everyday classroom materials will be tied to the helium-inflated balloon. The results of the experiments show that the balloon rises more slowly when an item is attached to it, and even more slowly the heavier the item, versus nothing attached at all. Just as expected, the balloon with nothing attached rose to the ceiling more quickly than any of the other balloons with items attached.


 * EXPERIMENTAL IMPROVEMENT AND FUTURE EXPERIMENTS:**

A way to improve this experiment would be to use a better quality balloon with more stretch to it making it easier to tie. Another improvement would be being more precise at measuring the helium that goes into the balloon. Having more practice tying balloons and using the helium tank would help to achieve this. A future experiment would be how many balloons it would take to lift a person. This would be an extreme feat!
