Introduction
Boom! It is fast. It is furious. It's Angry Birds! Just kidding. It is rockets. Rockets are or used to be toys. "Rockets were invented in China about a thousand years ago." Modern rockets are used as toys, weapons, and spaceships. We bought a model rocket that says it goes 165 m or 541 ft high. I want to find out if the box is right and find the real height.
How Model Rockets WorkModel rockets are cylinders with a nosecone and tail fins to keep it stable. The rocket we used had a motor, recovery parachute, and propellers for the nosecone inside. To launch the rocket, we put an ignitor in the motor. We used a remote control to send an electric jolt into the motor. Fire shot out the motor and boosted the rocket up. At the highest point, the recovery system was supposed to pop out, but ours crashed.

Steps1.Ben and I built the rocket.
2.We brought the rocket to the park. 3.I ran and measured 500 feet away from the rocket so I could measure correctly. 4.We launched it. 5.I measured how high it went with an altimeter from 500 feet away. 6.I launched again to get more data, but three tail fins came off. 7. The second launch gave no data because the rocket broke. DataWe found the actual height is 202(m). In feet it is 663 ft. The box says it would go 165(m). In feet it is 541 ft. The rocket went 122 feet higher than the box said.
