Projectile Motion: Rocket Launcher​ (20 points)

Picture
Question:
At what angle do we need to fly a paper rocket so that it travels the furthest?

Purpose:
To determine the ideal angle needed for a projectile to travel the furthest horizontal distance.

Common Core Standards:
  • CCSS.ELA-LITERACY.RST.9-10.3
    Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks, attending to special cases or exceptions defined in the text.
  • CCSS.ELA-LITERACY.RST.9-10.5
    Analyze the structure of the relationships among concepts in a text, including relationships among key terms (e.g., force, friction, reaction force, energy).
  • CCSS.ELA-LITERACY.RST.9-10.6
    Analyze the author's purpose in providing an explanation, describing a procedure, or discussing an experiment in a text, defining the question the author seeks to address.
  • CCSS.ELA-LITERACY.RST.9-10.7
    Translate quantitative or technical information expressed in words in a text into visual form (e.g., a table or chart) and translate information expressed visually or mathematically (e.g., in an equation) into words.
Materials 
Required:

  • Strip of paper about 2" wide and 7" long
  • Scissors
  • Glue Stick
  • Pen or dowel slightly thicker than the straw
  • Straw
Procedure: 
  • Go to Do It Yourself: Spitball Straw Rocket and create your own rocket
  • Once your rocket is completed, you will need to fly it at various angles to determine it's greatest horizontal flight.
Collection of Data:
  • Measure the horizontal distance traveled along with the angle of trajectory
  • Complete at least 5 trials for each angle.

Lab Report:
You will write up this lab in a Google Docs document or another "sharable" digital format. 
The work which is documented should be clear enough that others can follow it, understand it and if necessary, repeat the experimental procedure so as to verify the results.  It is a public record which is documented with the expectation that others could understand it. The ability to thoroughly document and to keep clear, understandable records of one's work is a key skill that the professional scientist must develop.

The Data section should include an organized and labeled record of the measurements. Both measured and calculated data should be listed; work should be shown. The Conclusion/Discussion should identify the speed values determined from each method. An error analysis should be performed; the accuracy and precision of each method should be compared; reasons for such conclusions should be explained.

Calculations: Provide proof that the angle that resulted in the greatest distance is explained through the Physics for Projectile Motion. 

Your lab report will include the following
  • Title (1 point): on the front cover of your lab notebook and on the top of page 1
  • Purpose / Objective (2 points): states the purpose of the lab
  • Apparatus (1 point): list of materials used in the lab
  • Setup (2 points): a diagram of the setup
  • Procedure (2 points): the steps to recreate the lab
  • Data (3 points): clear and organized measurements made during the lab
  • Calculations (3 points):
    • provide calculations in a neat and orderly outline form
    • provide proof that the angle that resulted in the greatest distance is explained through
      the Physics for Projectile Motion
  • Conclusion (4 points): completely answer the question using complete sentences
  • Discussion of Results (2 points): explanation of how the collected data provides support for the statement found in the conclusion; include an error analysis comparing your group's result to the class average
