• Question
• Which object (racquet, steel, marble, tennis, or
  golf ball) will have the most momentum when
  rolled down a ramp?

2

• Materials
• tennis, golf, marble, racquet, and steel ball
• ramp (?)
• stop watch
• ruler/meter stick
• balance

3

• Background
• Need to find momentum
• ?mv

raw data collected at lab station
calculated later
vd/t
4

• Hypothesis Variables
• If, then.., because
• manipulated (Independent)
• responding (Dependent)
• controls
• Procedure
• write specific directions how to do the lab
• a diagram is a good idea as well
• Make a Data Table ready to go for tomorrow
• one trial is fine, just make sure you are getting
  consistent times before recording

5

• Data Presentation
• momentum bar graph
• Conclusion
• was your hypothesis right?
• state your results (with numbers)
• explain your results
• compare to literature (internet) and cite you
  souce
• Evaluation
• give two weaknesses of your lab
• give two specific and reasonable ways you could
  improve these if you could do it again
