**Title** film canister rocket

Problem Scenario
how high can this rocket really go

Broad Question
how high can a film canister rocket fly?

Specific Question
will the amount of water change how high this can go?

Hypothesis
if I add more water to the canister, it will effect how high the rocket flies. I think it will fly higher.

Independent Variable:
amount of water used

Dependent Variable:
height of rocket

Variables That Need To Be Controlled:
Film canister antacid tablet type and amount used

Vocabulary List That Needs Explanation
carbon dioxide quadrant triangle

General Plan
==I plan on conducting my experiment at school. the whole experiment should take 30 minutes. ==
 * ...I will be measuring the amount of water put into the canister 1 tsp 2 tsp 3 ts

Potential Problems And Solutions

 * The wind could mess it up and throw it off course

Safety Or Environmental Concerns

 * do not luanch near windows or vehicles

Experimental Design
(add the correct headings from the experimental design page before beginning)

Resources and Budget Table

 * Item || Number needed || Where I will get this || Cost ||
 * film canister || 1 || teacher || 0 ||
 * antacid tablets || 3 || teacher || 0 ||
 * water || 1 cup || teacher || 0 ||
 * video camera || 1 || teacher || 0 ||
 * tape measure || 1 || teacher || 0 ||
 * grad cilender || 1 || teacher || 0 ||

Detailed Procedure
The standard for this step is that ** anyone **, ** anywhere ** should be able to repeat your experiment ** without ** having to ask you questions. This is a list of steps. Chances are good that you will need to revise this after you have done the experiment. You might include a well labelled diagram or the set up holding the quadrant to measure the height.


 * I will grab my equipment and walk out into an open area away from cars and windows.
 * I will take the lid off and put half of a tab of antacid and drop it down into the bottom of the plastic container.
 * I will add different amount of water to the container.
 * I will take a couple of steps back and it will take a couple of seconds to actually foam up and launch.
 * I will have a second person holding a tool to measure the height.
 * I will write down the data.
 * I will take a picture of how high it went.
 * Then when it hits the ground and lands I will go and pick it up.
 * I will repeat this experiment with different amounts of water.
 * I will probably do this three or four times.

Benefit to Community and/or Science
I learned that the space swells inside the canister. There was a snowboarder. The guy’s brain swelled out so they had to cut part of his skull out so his brain could get enough room. There is swelling and expanding.

Background Research
The carbon dioxide will take up the rest of the space and e ventually try and expand, but it is not expandable and it launches the water out of it and it explodes and launches us into the air. This is called thrust.(1)

I did a practice launch. I know it goes high because I watched it and it had a little bit of water in it. When I did it I walked over so I couldn’t see any sun and just watched it drop down. It dropped down faster then it went up.
