We had a full two hours today to design and construct our rocket. Unfortunately we could not do much further research because the laptops wouldn't work in Mr. Henderson's room, but I printed out a few pages on how to design bottle rockets, and Mallory took very detailed notes. While designing, we had to take in to consideration all of the information that we had collected from our research. The rocket design that we have come up with focuses on stability and power. It has a large pressure chamber with an extra bottle on the top to improve aerodynamics, and also has a dowel rod that extends into the extra bottle. This rod doesn't puncture the pressure chamber, and should help with the rocket's stability if we center it correctly. I am really pleased with our construction thus far, and I hope that we will be able to continue our progress.
Mallory I also need to find an idea for the nose tip. I think plastic will do. It's just that I cannot find anything laying around my house that can be used. I will probably search better tonight again, and if I see anything I will bring it in. Can you try and find a strong parabolic or shaped nose tip for the rocket?
Brittany; are we putting an additional piece over the dowel rod? I'm assuming that's what you're suggesting when you talk about the parabolic shape for the nose tip? If so, I will definitely look. I'll also try to find some spray paint for the role decorating process.
ReplyDeleteAlso, after doing some research I found that having the nose tip be parabolic is best for our rocket because a blunt shape would just slow it down. It seems like we're on the right track!
