Make
a Conjecture
In
this segment, you'll be asked to think about the mathematics
of modeling the light intensity in the ocean. You can
view a movie segment of an underwater dive and a launch
of this lesson in the classroom.
Gather
Data
Take
a virtual dive under water to gather light intensity
data, conduct an experiments using a CBL or watch students
conduct experiments using a CBL. The goal of this segment
is to produce a data set and to initially examine the
data set.
Analyze
the Data
Three
different methods of analyzing the data are investigated.
The first uses an interactive grapher with sliders to
adjust the values (parameters) in a function. A second
method explores the data using discrete mathematics
and difference equations. The third method linearizes
the data using logarithms.
Reflect
on your Work
The
final segment of this activity extends and connects
the learning of this investigation to other concepts.
