A student plays tennis several times a week. She notices that the tennis ball seems to bounce higher on some courts than on other courts. She wonders if this has something to do with the surface of the
court. Design an experiment to see if her hypothesis is correct. Include these elements in your
response:
• State the hypothesis.
• Identify the factor to be varied.
• Identify two factors that should be held constant.

hypothesis Ball bounces higher on asphalt than concrete, factors to be varied asphalt court and concrete court, constant tennis ball and height dropped from.
