Introduction:
In this project my partner and I had two rockets. They were made out of one-liter soda bottles. One of them had a round nose cone, and four fins. The other had a pointed nose cone and two fins. We fired both rockets to decide which one we wanted to shoot, and after we shot both of them, we decided that the rocket with the round nose cone shot farther, so that would be the rocket we would use. Our question was “Will the water amount effect the height the rocket will go?” Our hypothesis is “If the water amount affects the rocket height, than we should have an average of a quarter of the water amount that the bottle will hold in our rocket”
Data:
The way that we collected our data was that when we launched our rocket we would change our variable (water amount) then we would measure both the angle of elevation and the distance from the launcher. To get the hang time of the rocket someone would time how long the rocket was hanging. To get the height of the rocket we would use the equation tan(angle)= h/d.
Procedure:
How we went about testing is we had fired both of the rockets and we looked at them and looked to see which rocket fired the highest, then we decided that the one that went the highest would be the one we used. So we decided, then started making modifications to that rocket. The variables that we kept the same where pressure, mass, shape, dimensions
Conclusion:
Our hypothesis was, “If the water amount affects the rocket height, than we should have an average of a quarter of the water amount that the bottle will hold in our rocket.” we had difficulties testing this because we had to vary our water amounts to find our end result. We had some errors with finding the right amount; we filled it up, and it wouldn’t fly as high as we needed, we filled it up too little, and it would have too much pressure and leak. These errors helped us make changes, and improve our rocket by telling us what we needed to change, and make better. We also had some recommendations by other students to make our rocket have only two fins instead of four. Also to have a pointed tip, instead of round. This was a fun project and we learned a lot. We learned that we need to pay attention to Brian because if we don’t we will not learn the things we need to, and pay the price.
