For the last two weeks we’ve been working on the scientific method and the process to work through an experiment. We started with looking at when our heart rate was lowest. The class already knew it would be highest when exercising, but had mixed ideas on when it would be slowest.
Our second experiment was what made a paper rocket fly the farthest. The biggest reason I chose this was that the rockets could be made in under 5 minutes. This allowed the class to manipulate the rockets a ton to see what worked.
Here is the video we used for building our rockets:
With in the class we set up a rocket test range from one end to the other.
Within the classroom range, the majority of the rockets went 1-4 meters. A few of the students were hitting 6 meters. By day 2 we had hit 9 meters (AKA the back door). With this in mind we began to plan for the ultimate range: The GYM!
Friday afternoon, we prepared to head to the gym. We spent the afternoon adjusting and firing rockets. The farthest that we got with straws was about 12 meters.
( Post it notes and rockets mark where we got to)
As an added bonus to this project, a friend of mine, who happened to be an engineer, came in Friday afternoon for our final test day. All week the class’s goal had been to beat his rocket. Friday afternoon was met with a surprise when he showed off his rocket.
This was powered by an air compressor. The class was not impressed. Many cries of “That’s not fair!” and “He’s cheating!” could be heard. His rocket was able to hit the back wall (on his second attempt). Once they realized that they got to use it as well they were much happier. No one was able to match his, though a few got close.
We made rockets, we shot rockets, and in the spirit of Science Max, we “Maxed it out” with our compressed air launcher. Overall, a very successful experiment.
