  • Paint
  • Duct Tape
  • Hole Punch
  • Googly Eyes
  • Electrical Tape
  • Yellow Construction Paper
  • 2 Two Litter Soda Bottles
  • A Card Board Box
  • String

Day 1

We will first collect our materials and set them aside for later on in the project.

Day 2

Cut the 2nd bottle if we are using a 2nd bottle, then attach it to the 1st bottle to make room for the parachute.

Day 3

Grab the cardboard and also the tape, then measure the cardboard and cut it the way we want it to be for the fins of the bottle rocket. Then duct tape the fins to the bottle rocket, and then add the odds and ends to the fins on the rocket. Tape the same height to all the fins, so that way one fin don’t fly off.

Day 4

Cut the bag into a circle and punch 4-6 holes in it then attach the string to it and then attach it to the bottle rocket so that way our rocket has a parachute to land.

Day 5

Then create the pine or the nosecone to keep the parachute together till we launch it, when we attach the nose cone we have to make sure that it is secured before we launch the rocket.

Day 6

Attach the nose cone to the bottom of the bottle rocket, then secure it with duct tape.
Then finish the bottle rocket, with the last materials that you need for the rocket.

Rules of this Project

  1. The Body of the rocket must be made from soda bottles (not water or juice) 2-Liter or less in size

  2. Nosecones and fins can be made of cardboard, plastic, styrofoam, or other material

  3. No Metal parts anywhere on the rocket

  4. No commercial or pre-made parachutes allowed

  5. Rockets parts may separate during flight, but must remain attached together

  6. Completed rockets must weigh less than 300 g

  7. All rockets will be launched with the same air pressure: 75 p.s.i.

  8. No supplemental forms of energy for launch will be allowed

  9. Rockets will be timed from the moment of launch until it hits the ground, falls out of sight, or becomes stuck in a tree, powerline, etc.

Vocabulary Words

Force: The strength or energy as a attribute of physical action or movement.

Pressure:The continuous physical force exerted on or against an object by something in contact with it.

Launch:Set in motion by pushing force or allowing to roll into water.

Apogee: The highest point in development of something, usually the climax.

Aerodynamic: Of or having a shape that reduces the drag from air moving past.

Center of Gravity: A point from which the weight of a body. It is the same as the center of mass.

Recovery: To return after the normal state the object was in first.

Prototype: The first model of something, like a machine, from which others form or develop another of the same thing.

Stability: The state in which the object is stable.

Construction of the rocket

Rocket designed and built with some attention to detail. Above average knowledge. Center of gravity analyzed and adjusted. Some creativity in design.

Performace of the rocket

Rocket launch was somewhat successful. Flight was high and straight. Recovery system deployed, but may not have been ideal. Total time was between 7 and 12 seconds.

Our launch times

First launch- 4.82

Second launch- 7.63
