A student performs an investigation to determine if keeping plants in a
greenhouse will reduce the amount
of water lost to evaporation. The
student hypothesizes that if a plant
is in a closed, humid environment,
then less water will be lost to
evaporation. The student places the
plants in beakers of water and then
sets some beakers inside and some
beakers outside of a greenhouse,
She then measures the amount of
water lost from each beaker, Which
table should the student use to
collect the data needed to test her
hypothesis?
