RESEARCHPROJECT:DETERMININGSTORM
SURGEHEIGHT
Your mission: You are joining a team of scientists who are studying the effects of
stormsalongtheU.S.coast.Yourtaskisto
pick a storm event for a coastal location and
design a research plan to help you gather
data about the water height before, during,
and after the storm. You already know
something about the typical or average water
height in the area due to tides. Your goal now
is to determine the additional effect a storm
can have on water height. Once your plan is
accepted, you are to carry out your data collection, analyze it, and report your findings to
theteam.
