Balloon Lab Report

Problem:
The goal of the balloon lab was to get a balloon attached to a line all the way across the room. One limitation was that we could only use one balloon, two straws, and tape. The circumference of the circle at its largest point couldn’t be larger than 100 cm.

Procedure/Results:
Trial Number| Distance Traveled (CM)| Time (sec)| Velocity (CM/sec)| 1| 346| 1.02| 339.2|
2| 471| .79| 596.2|

This vehicle worked the best because it had the highest average distance traveled, 518.33 CM, as well as the highest individual trial, 527 CM. The average distance traveled was higher than the other two averages, 293.75 and 129.8, combined.

There were a couple of reasons why this design worked the best. On reason is the straw on the end of the balloon. This controls the amount of air coming out of the balloon so the air doesn’t all rush out. Another reason is the straw connected to the balloon. This keeps the vehicle moving forward. The last reason is the straw on the line connecting to the straw on the end of the balloon. This keeps the air flowing straight and makes the vehicle go forward. My group and...
