**Purpose**

 * the purpose of this bubble lab was to calculate the bubble's velocity once you determine the bubble's change in position, and time it took to do so.

Materials

 * 1) 1 blue tube
 * 2) 1 red tube
 * 3) 1 green tube
 * 4) garbage can
 * 5) stop watch

Procedure

 * We placed a recycle bin on it's side on a lab table, then we set the tube at an angle so the air bubble would raise to the top. Using a cellular phone's stopwatch we recorded the time that elapsed at every 20 cm until it got to the end.

Data

 * = ===Blue=== ||= ===Red=== ||= ===Green=== ||= ===Distance=== ||
 * = 5.05 ||= 3.10 ||= 7.23 ||= 20 cm ||
 * = 9.09 ||= 6.04 ||= 14.52 ||= 40cm ||
 * = 13.71 ||= 9.04 ||= 21.31 ||= 60cm ||
 * = 18.55 ||= 11.97 ||= 28.60 ||= 80cm ||

Conclusion

 * We have concluded that an object's velocity is determines by it's change in position over a certain amount of time. Velocity not only have a magnitude, but it also includes a direction, positive or negative, in which the object is traveling.
