Intersession Reflection
Well, I guess it was KINDA fun. I didn't really enjoy it much, and I missed a few days because of the car accident, but launching the rockets was fun. Making them wasen't so fun but I did learn some new things such as what yaw and pitch means, or about the people that invented new planes and stuff. Sometimes it was like really boring that I was like almost falling asleep and sometimes I didn't even understand the homework but I tried my best... Any ways, when I was told I had that intersession I wasn't really happy and I thought it was going to be way boring, but it was kind of fun so if I ever had to go to that intersession again, maybe I would. Happy Spring Break!-Daniela

Rocket Launching Rules
Rocket Launching Rules:
1.Materials - I will use only lightweight, non-metal parts for the nose, body, and fins of my rocket.
2.Motors - I will use only certified, commercially-made model rocket motors, and will not tamper with these motors or use then for any purposes except those recommended by the manufacturer.
3.Ignition System - I will launch my rockets with an electrical launch system and electrical motor ignites
4.Launch Safety - I will use a countdown before launch, and will ensure that everyone is paying attention and is a safe distance of at least 15 feet away when I launch rockets with D motors of smaller, and 30 feet when I launch larger rockets.
5.Misfires - If my rocket does not launch when I press the button of my electrical launch system, I will remove the launcher's safety interlock or disconnect its battery before allowing anyone to approach the rocket.
6.Launcher - I will launch my rocket from a launch rod, tower, or rail to ensure that the rocker flies nearly straight up. I will use a blast deflector to prevent the motor's exhaust from hitting the ground, and I will cap the end of my launch rod when it is not in use.
7.Size - If my model rocket weights more than one pound (453 grams) at liftoff or has more power than a single G motor, I will check and comply with Federal Aviation Administration regulations before flying.
8.Flight Safety - I will not launch my rocket at targets or near airplanes, and will not put any flammable or explosive payload in my rocket.
9.Launch Site - I will launch my rocket outdoors, in an open area and in safe weather conditions, (*LITTLE OR NO WIND) and will ensure that there is no dry grass close to the launch pad (*OR IN THE FLYING FIELD).
10.Recovery System - I will use a recovery system such as a streamer of parachute in my rocket so that it returns safely and undamaged and can be flown again, and I will only use flame-resistant or fireproof recovery system wadding in my rocket.
11.Recovery Safety - I will not attempt to recover my rocket from power lines, tall trees, or other dangerous places.

Why Some Planes Did Fly And Others Didn't
Well, I think all the planes did fly because they were built properly. The only plane that didn't fly was Cesars, I think. I think his didn't fly because either he didn't make the rocket right, or maybe there was something wrong with the rocket launcher. It maybe couldn't have been the rocket launcher thought because it worked perfectly well for all the other rockets.

Yaw, Pitch, Roll, ect...
Yaw: Nose left and right
Pitch: Nose up and down
Roll: Wings/Body left and right
Dihedral: A figure formed by two intersecting planes.
Static:
Dynamic:
Aerodynamic: Designed or arranged to offer the least resistant to fluid flow

Explain The Bernoulli Effect and then Newtonian Theory
The Bernoulli Effect:
The top of the wing is curved, so that the air that is moving over it has less pressure, moves faster, and moves further. The bottom of the wing is flat so that it has more pressure, moves slower than the air above it, and pushes up harder than air above the airfoil.
The Newtonian Theory: The air on the top has more pressure than the bottom, and it tried to move further. On the bottom of the wing, the air hits the wing, then it bounces back off.

Improved or not Improved?
I didn't improve my plane. I changed the wings and made them kind of into semi- circles at the ends, but it just made the plane worse. I think that if I would have made them kind of sharp, they would have cut through the air and it would have been better.
Defeniton of Fligth
My defenition of fligth is an object in the air that is using the four forces of fligth.

Homework....
...Hi Mr Shulman... Since I'm in an intersession were I don't understand anything, I will try to act smart... uh....yeah.... um, any ways, how are you? You said we had to write a paragraph thingy so... here it is! Hopefully this will count as a paragraph so it will be like I'm suposely smart! :D so yea... Any ways, I think this is how you write the blog thingy and I think I finished with my paragraph so... Bye Mr Shulman!!!!
-Daniela
P.S. Is this even a paragraph???
