Kinematics 1: Speedometer Lab

Question:
What is the speed of the constant motion, battery-powered car?

Purpose:
To
 determine
 the
 speed
 of
 a
 constant 
motion,
 battery‐powered
 car.

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:


• Battery‐powered
 car
• 
meter
stick
• 
stop watch 
or 
timing 
device

  

Procedure:
Devise your own method for determining the speed of your car. 

• Keep the car on the floor.
• Perform several trials and record your data.

Lab Report:
The work which is documented in a lab notebook 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.

Your lab report will include the following

• Title: on the front cover of your lab notebook and on the top of page 1
• Purpose / Objective: states the purpose of the lab
• Apparatus: list of materials used in the lab
• Setup: a diagram of the setup
• Procedure: the steps to recreate the lab
• Data: clear and organized measurements made during the lab

• Calculations: provide calculations in a neat and orderly outline form

• Conclusion: completely answer the question using complete sentences

• Discussion of Results: 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
