Today we had to complete a launch that lasted a minimum of three seconds, with our parachute on. Me and my partner Melody thought that if we added fins, and a cone, that it would make our rocket stay in the air for a longer amount of time. However, we found that our launch lasted exactly 3 seconds, our launch wasn't as successful as we thought it was going to be. We picked out problems, that we thought was the cause of our unsuccessful launch. We think that our fins were to big, and they weren't evenly placed on the rocket. We also thought that our parachute wasn't big enough, because it didn't catch any wind at all when the rocket was falling after it reached its maximum. Also, with our next launch to plan to make our rocket longer, because observing from other groups, the ones that had the longer rockets stayed in the air for a longer amount of time.
Hi guys! Cute blog :) How big did you guys make your parachute? Keana and I are going to try use a bigger parachute too; we're planning to use one of those white garbage bags or something like Rachelle and Shawnie's rocket because theirs was in the air for a long time. Hope your ideas work!
