A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape‚ and in doing so provides a thrust that propels the rocket in the opposite direction. Newton’s laws can be used to explain this his laws in the simplest terms can be explained like this: First law- Objects at rest will stay at rest and objects in motion will stay in motion in a straight line unless acted upon by an unbalanced force.

Soda bottle rocket Purpose The students will investigate the effect of the rocket length upon the distance of flight. The students will also investigate the mass upon the distance flight. Background The students will proof Newton’s third law of motion states that for every action there is an equal and opposite reaction. Newton’s third law also applies to rockets. A rocket gets its lift from the gases pushing out of its tail. The force of the rocket pushing on these gases is the action force

After much hard work they finally build a rocket that launches into the air. The story keeps progressing and their rockets keep flying higher‚ as they get new ideas on how to build their rockets more effectively. One major person in helping them to develop their rockets is Miss Riley‚ their chemistry teacher
