Day 8 (3/29)

What was common with all of our launches was that all the rockets were able to launch. Another thing that was common was that all of the rockets were angled into the wind so they would go straight. A final thing that was common was that lots of the rockets corkscrewed or at least turned a little.

Some of the launches failed because of the electrical pyrotechnics used for the igniters, they were cheap so they didn’t always work. Another reason some of the launches failed was because the alligator clips or other wired were crossed or because the wires were touching the metal blast shields which created a short circuit

We used each of the steps of the scientific method in our rocket building/launching process in this way: We observed (in the launching process) that the wind was blowing fairly hard so we angled the rockets into the wind. We asked the question (in the building process), What type of fins will work best? We created an educated guess (hypothesis) of which fins would work best by getting some inside information from an expert (Mr. Davis). We conducted and experiment (launched the rockets) to see which types of fins worked best. Then we created a conclusion; we are not sure which fins work the best because there may have been an error in the launch system (the launch pole was tilted) and the data has not been fully analyzed.
