How will the length of the tube affect the distance the marshmallow travels?
IV: The length of the tube
DV: The distance marshmallow travels
CV: How hard we blow and the height we blow at.
For this experiment we will test if the length of the tube will affect the distance the marshmallow travels. First of all, we had to cut three rectangles out from manila folders. We than created three tubes of 3 different lengths. We will keep the height of the tube the same 160 cm and we will blow the same amount for each one. We will then shoot the marshmallow three times at each tube length: 46.5 cm, 34.2 cm, 22.5 cm. We will than measure the distance the marshmallow travels each time. It is also important to note that each time we blew into the tube the marshmallow was on the same end that we were blowing into. We then recorded the distance. good

**Blowing the hardest at same height of160cm**
Verbal Statements: After doing this experiment, we found that as the length of the tube increases, the distance of the marshmallow from the point in which you started increases.
How will changing the amount of blow affect the distance the marshmallow travel?
IV: Force of the air
DV: The distance the marshmallow travels
CV: The height of the tube and the tube length.
Basically repeated the exact same procedure except that for this experiment we will test if the strength of the blow will affect the distance the marshmallow travels. We will keep the tube length the same and height of the tube the same, we will use the 22.5cm tube and blow at 160cm. We will then blow soft, medium, and hard. We will do this three times each and measure how far the marshmallow traveled each time and then average the data.

**22.5 cm tube at 160cm**
Verbal Statement: As the force of the blow increases, the distance of the marshmallow from the starting point increases. In this experiment we kept everything the same except for how hard we blew (soft, medium, hardest).

How will changing the height the marshmallow is shot at affect the distance traveled by the marshmallow?
IV: The height where the marshmallow is blown at
DV: The distance the marshmallow travels
CV: How hard the blow is and the length of the tube
Basically repeated the exact same procedure except that for this experiment t we will test if blowing the marshmallow at different heights will affect the distance the marshmallow travels. We will keep the tube length at 22.5cm. We will also blow with the same force each time. We will then test each height three times at .5m, 1m, and 1.5m. We will measure the distance traveled by the marshmallow each time and average the data at the end.

**Different heights, same tube length (22.5cm), blowing hardest**
Verbal Statement: As the height of the shooter increases, the distance of the marshmallow from the starting point increases. In this experiment, the height is the only thing being altered.
all excellent!
all excellent!
Conclusion
In the marshmallow experiment we came up with the equation F x t= (Delta) mv
For the equation above these are the meanings of the terms/symbols: f (force), t (time), m (mass) and v (change in velocity). Technically speaking F x t is also known asp J (impulse). Another way to write this equation is j=delta p. J is the amount of impulse and delta p p is momentum ... an impulse causes a change in momentum is basically the product of the force and time.
Using this equation for Experiment 1, as the time the marshmallow experiences the force of the tube increases, the change in velocity increases proportionally. The longer the tube, the longer it takes for the marshmallow to travel through the tube. This will result in the marshmallow traveling greater distance because of the increased velocity. For instance, in our experiment, on average the long tube (46.5 Cm) shot the marshmallow 8.24 M, the medium tube (34.2 M) shot 7.27 M, and the short tube (22.5 M) shot 3.9 meters. This clearly demonstrates that the longer the tube the greater the distance it travels and the shorter the distance the less it travels. This is ultimately due to the amount of time in the tube. because the force has longer time to act on the mallow, speeding it up more
In experiment 2, we found that as the force of the blow increases, the distance of the marshmallow from the starting point increases as well. This could be proved by the following equation, J= delta x p. This basically means that marshmallow will travel the farthest during the hardest blow. This is because if the force acting upon the marshmallow is increasing, the velocity is proportional with it. Therefore, it would gain velocity as well. ??In essence the greater the impulse, the greater the velocity. Therefore, it travels the farthest during the hardest blow. This could be proved from our data and results. The soft blow averaged about 3.1 M, the medium blow averaged 4.2 M, and the hardest blow averaged 6.77 M.
In Experiment 3, we found that as the height of the shooter increases, the distance of the marshmallow from the starting point increases. In this experiment, the height is the only thing being altered. Therefore the speed remains the same and the marshmallow experiences the same amount of force. It also experiences the same amount of time and impulse. So therefore the marshmallow is leaving the tube at the same speed. The reason why the higher height (1.5 M) traveled a greater distance was due to the fact that the marshmallow had more time to hit the ground than the shorter height (.5M). Therefore it is able to travel a greater distance. This can be proved from a data from which we tested 3 different heights. Are averages for the three heights were: the short shot at .5m hit the ground at 2.6M, the 1M height hit the ground at 3.58M and the 1.5M height hit the ground at 5.82 M. This set of trials did not test how the independent variables affect the momentum like the other two. However, it proved how the object will travel a greater distance when acted upon from a taller height.good
Error Analysis proofread! lots of spelling errors in this paragraph
We tried are best not to have any errors in our experiment. However, there was a few things in which we had errors and things that we could have done better. One thing that went wrong in our experiment was that we didn't use the same marshmallow throughout the experiment. Some were larger than others and some were small. Another possible problem was that we used flower some times and maybe that had an affect in which some were shot father. Lastly, our measurements might not have been a hundred percent correct. Next time we should be more precise with our calculations. We could expand upon this experiment by testing other things like if the mass of the marshmallow affects the distance. I really enjoyed this experiment and would recommend it to everyone. me too! nice job!
