DeScRipTiOn

• Stretched rubber band seven different lengths.
• Each length with five trials.
• Found averages from our data.
• Plug points into calculator.
• Make scatter plot and then find a line of fit.
• With Line of Fit try to predict
• How far the rubberband would have to stretch to
  fly 100 meters?

ImpOrtaNt QueStioNs

• How far would the rubber band have to stretch to
  fly 100 meters?
• How does the amount you stretch a rubber band
  affect how far it flies?
• How far would a rubber band fly if you stretched
  it 2 meters?
• What do you think the a, b, and c from the
  equation represent in the context of the
  experiment?

AnSweRs To qUesTioNs

• To fly 100 meters the rubber band would have to
  be stretched 70.75 meters.
• The amount you stretch the rubber band will give
  you the results of how far it will fly the
  farther you stretch it, the farther it flies!
• If the rubber band was stretched 2 meters, then
  it would fly 16.01 meters.
• a determines how far the rubber band flies,
  but it depends on the elasticity of it.
• b how long the rubber band is.
• c there is no c in the context of this
  experiment.

mY quEstIonS

• Would the end results be different if the
  experiment were done outside?
• Would the height of the desk affect how far the
  rubber band flies?
• When x zero on the graph, what does that mean?
