Marshmallow Shooter Lab

Key Question 1:
How will the length of the tube affect the distance the marshmallow goes?

Materials:

why is your data table up here before you defined variables and stated your procedure?  Doesn;t make sense in the flow of the report...

Long (46.5cm)	Medium (34.2cm)	Short (22.5cm)
7m	6.21m	3.9m
8.45m	7.6m	4.1m
9.26m	8m	3.7m
Avg: 8.24m	Avg: 7.27m	Avg: 3.9m

IV: The length of the tube

DV: The distance marshmallow travels

CV: How hard we blow and the height we blow at.

Procedure:

For this experiment we will test if the length of the tube will affect the distance the marshmallow travels. We will keep the height of the tube, 160cm, and how hard the blow is the same. We will then shoot the marshmallow three times at each tube length: 46.5cm, 34.2cm, 22.5cm. we will measure the distance the marshmallow traveled each time and average them to get sufficient data. good

Conclusion: 
     We concluded that the distance the marshmallow traveled increased when we increased the tube length. The marshmallow would travel a farther distance because the marshmallow would experience the force of the blow longer in a longer tube and experience the force of the blow less in a smaller tube. show how this is based on the equation. ... how does a longer time make more distance?

Key Question 2:

How will changing the amount of blow affect the distance the marshmallow travel?

Soft	Medium	Hardest
3m	4.3m	6.2m
2.65m	4.3m	7m
3.55m	4m	7.1m
Avg: 3.1m	Avg: 4.2m	Avg: 6.77m

IV: How hard we blow

DV: The distance the marshmallow travels

CV: The height of the tube and the tube length.

Procedure:

For this experiment we will test if how hard we blow will affect the distance the marshmallow will travel. We will keep the tube length and height of the tube the same, we will use the 22.5cm tube and blow at 160cm??  did you mean height?. We will then blow soft, medium, then hardest, three times each and measure how far the marshmallow traveled each time and then average the data.

Conclusion:
        We concluded that the harder you blow, the farther the marshmallow will travel. The marshmallow would travel farther when we blew at a harder force and it makes sense because when you increase the force, the distance increases as well. Ft = M(delta)V really the velocity increases...then say how that increases the distance...

Key Question 3:

How will changing the height the marshmallow is shot at affect the distance traveled by the marshmallow?

.5m(height)	1m(height)	1.5m(height)
2.6m	3.5m	5.8m
2.5m	3.6m	5.7m
2.7m	3.65m	5.95m
Avg: 2.6m	Avg: 3.58m	Avg:5.82m

IV: The height the marshmallow is shot at

DV: The distance the marshmallow travels

CV: How hard the blow is and the length of the tube

Procedure:

In this experiment we will test if blowing the marshmallow at different heights will affect the distance the marshmallow travels. We will keep the tube length, 22.5cm, and how hard we blow the same. 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. good

Conclusion:
        We concluded that when you increase the height the marshmallow was shot at, the distance traveled by the marshmallow increases as well. This happened because the marshmallow had more time to fall because it was at a higher height and had more time to travel farther. but show using equation what the velocity was when it left the tube...
