Making are nose cone

This is are rockets body and are soon to be nose cone.

Are nose cone idea.

Getting are nose cone to say on.

Making it heavier and look better.
We soon learned that it was still not heavy enough so we cut the top of the nose cone back opened, and stuffed it with pare. Then we taped it back up.

The final touches.

Trying to make are fins

This was a design for the fins.

Are first idea was to us old cards. We soon learned after drawing that the fins they were too small.

So then we debited to us cardboard. Then we destined that it would be a good idea, yet it was still too small.

Finally we got are perfect fins, that were made from cardboard.

Nose Cones, And Fins

Nose Cones
There are three type of cone conical, parabolic and ogive. Are group desisted to use the parabolic because it has less drag then the other cones yet, it has more surface area.  This nose cone is long and has a round point at the top. The ogive is long and rounded, and as for the conical it is like a triangle it side is angled then comes to gather a point on the top.

Fins

The fins are you to stable the rocket my group saw that there were 3 types of fins. We decided that we would use the second won on the list because it seemed to look the most aerodynamic.

Observations

 Bottle                                                                    Water                                Observations    

 2L                                                                          All Full                             The bottle did not go very far and when the bottle went up it curved.

 2L                                                                          ½ Full                               It went pretty far but not super high up but not low.                                                      

 2L                                                                          ¼ Full                               It went about ½ as much as the ½ full 2L and came down slow.

 2L                                                                          20%                                 Went as high as the ½ 2L and, went up pretty straight up.

 2L                                                                          None Full                         It went low then came tumbled down

 1L                                                                          ½ Full                               Low and, then it tumbled down

 1L                                                                          ¼ Full                               Low and curved a lot as it tumbled down.                                                                                                                                                            

 1L Different shape                                                ¼ Full                               Medium low yet, not a lot of tumbling on the way down.    

 Made rocket                                                          ¼ Full                              Went far but, not high.
