Body Tube
We were confused about what kind of material we should use to make for the body. I thought that maybe a paper towel roll would work but Andrew said that one of those rolls actually weighs a lot. We decided to use a body tube using this kind of making process. Ultimately, he suggested that we make our own rolls, using a method of wrapping and glueing layers together. We both want the body tube to be somewhere around 15 inches long but it depends on the weight of the whole rocket.
Fins
We researched fin designs and I proposed we use a clipped parallelogram with a 4-fin placement. As seen below, the clipped parallelogram design in the first column in the second row and 4-fin placement in middle column, last row.

Nose Cone
Morgan and I are most likely going to use balsa wood for nose cone. We're not sure how we're going to make it, like what exactly the process is. I proposed that our nose cone be pointy rather than curved so we're making our nose cone pointy. Then for a shock cord, we're going to use another shock cord from an old rocket.
Engine Housing
We were told that our body tube would fit our motor so we wouldn't really need any engine housing other than a metal clip that would keep our engine in the rocket.
Parachute
I guess we're going to just use a trash bag and punch four holes in it then tie the parachute to the shock cord.
Additional Components
if we ultimately decide to do an engineering challenge, we would like to do the package deployment idea. If we do a package deployment, at some point the package will deploy and there will be a second parachute specifically for the package that will let it float down to the ground safely.
Things We Need to Consider
5:1 thrust to mass ratio is the lowest we can go. 6 or 7 would be even better.
The maximum that our rocket can weigh is 214.6 grams. Considering that the motor will weigh about 80 grams that give us about 130 grams for the rest of the rocket to weigh.
