Your family is moving and isn't sure how to best overcome friction
while moving furniture. You have a spring scale, wood blocks to
represent your furniture, and sandpaper, aluminum foil, marbles,
and olive oil as possible surfaces to slide your furniture over.
Design Experiments Design an experiment that will help you
determine which material will reduce friction the most.
You know that friction occurs between surfaces when they slide
against each other. If you measure the applied force required
to push something across a surface, you know that your applied
force would increase/decrease) as friction increased.
STEP 1 Measure How would you determine your
applied force in this experiment?
STEP 3 Create Data Tables Draw the data table
you would use when performing this experiment.
STEP 2 Control Variables What variables would
you have to control to keep your results accurate?
