helicopter lab report Essay Example
Research Question:
At what speed will the helicopter fall by adding more paper clips to its base (the bottom)?
Variables:
Independent Variable: Amount of paper clips
Dependent Variable: Speed
Constant:
I. Same Helicopter
II. Same Timer
III. Same height (2m)
Hypothesis:
My hypothesis is that the more paper clips added to the base of the helicopter, the speed will increase.
I think this will happen because gravity will pull the helicopter down and the opposite force (air resistance), which is acting on the wings will get weaker because the wings will fold upwards. This will cause less for the air resistance to act on which will cause the speed to increase.
Method:
For our helicopter lab, we first measured two meters on the wall so we have will drop the helicopter at the same place. Then, Eliah will drop the helicopter and Holly will time how long it takes with the stopwatch. We repeated this step for three mores tests and with two, three, four, five and six paperclips attached to the base. Then, we found the average speed of each paperclip and recorded our results into a graph.
To make our test a fair test, we made sure it’s the same person timing and dropping the helicopter. Also, we always dropped the helicopter from two meters.
For our safety, we made sure that we are in an empty space so we don’t bump into anyone or the paper helicopter doesn’t go on someone’s head. Also, we made sure that we are not next to any chemicals or flamed Bunsen burner so when we pick up our helicopter, it won’t catch on fire or be covered by any chemicals that could harm us.
