Robert loves bouncey balls. he sees an advertisement for the bounceymax bouncey ball, which claims
that it bounces at least twice as high as any other bouncey ball on the market. he buys the bounceymax
and decides to test to see if the company's claim is true, to do this he sets up an experiment with his
favorite bouncey ball and his new bounceymax. he begins by taping a meter stick to a wall. with the
of a friend he drops each bouncey ball from four different drop heights and records bow high they
bounce. he drops the bouncey balls from 100 cm 75 cm, 50 cm, and 25 cm. he drops each bounceyball
and with his friend's , records how high each rebounds. he records his data in a data table.
what is the test/independent variable?
what is the outcome/dependent variable?
how many different types of test/independent variable are there?
what are the different test/independent variable types?
how is the outcome/dependent variable being measured?
what variables are kept the same (controlled) through the experiment?
are there any other variables, besides the test/independent and outcome/dependent variables, that are
changed during the experiment?
if so, what are they?
is the experiment a fair test? why or why not?
