Soaring Straws

The lab soaring straws told me a lot about the relationship between elastic potential energy and gravitational potential energy. On our graph when the elastic potential energy was risen which was the stretch of the rubber band, the gravitational potential energy was also risen. This is because the further the rubber band was stretched was the higher that it went. For example, when we launched the rubber band from a two centimeter stretch, the straws gravitational potential energy was 2.943 millijoules. When we launched it from a three centimeter stretch it's G.P.E was 5.886 millijoules. From the stretch of the rubber band the height doubled. The G.P.E was the height that the straw went. That is the relationship between gravitational potential energy and elastic potential energy.

During our data collection there were a couple of errors that happened. First, when we were measuring our measurments they were not exact. Also, since we did it over two different days we got different launchers which mad different results. Ways to enhance the lab was to make every launcher the same. Some launchers shot very high but some did not. Usually, the thick rubber bands shot lower than the skinny ones. Also, we could have our measurments a lot more accurate because we could have made the ruler more steady and watch the hieght of the straw better. Finally, that is what the lab soaring straws taught me and how it can be a lot better.

“One Weird Watson”
by Mets57

Kenny
Intelligent, kind, and frightened
Who loves his family
Who feels worried about the Wool Pooh
Who needs a few good friends
Who shares dinosaurs with Rufus
Who fears the Wool Pooh
Who’d like to see his brother get punished for his crimes
Who dreams of losing his lazy eye

Who ends up being a member of “The Watson Pet Hospital”

“The Wool Pooh”

Wool Pooh
Crazy, dangerous
Killing, torturing, swirling
Quick, powerful, slow, beautiful
Loving, soothing, relaxing
Calm, slow-moving
