Surface-Area Experiment
J
ulie and Art want to find out how
surface area
affects
evaporation. They decide to do an experiment. They have
some plastic boxes to put water in, some graph paper, and a
set of measuring tools. They are ready to start.
Julie has an idea for
measuring the surface area
of each box. She traces
around each box on graph
paper. She uses a meter tape
to measure the distance
between the lines on the
graph paper. The lines are
1 centimeter (cm) apart.
