Shedding Light on the Subject. Have you ever noticed how the amount of light differs the further you are under water? I’d like you to consider the environment of
the dolphins pictured and how the light intensity changes from the surface of the water to the bottom of the ocean. So thinking about light intensity, I’d like you to answer these two questions, or
work on these two problems for a minute. I’d like you to write one or two questions whose answers will be mathematical equations. And I’d like you to predict what kind of graphs and equations are involved in answering your
questions. And I’d like you to include a sketch of your of the types of graphs you’ll be getting. So go back up… well,
look at the picture. Look at the paragraph. We want to consider the environment, not necessarily dolphins, but the environment.
How depth
affects light intensity.
Yeah, that definitely…
That’s a big
one. I don’t know how.
Write down your
hypotheses, questions.
Well, the deeper
we go…
The darker it
gets.
The more light
[inaudible]…
Can we predict the amount of light at a given depth of water?
Yeah. That’s
going to be hard, though.
It depends upon
if water…
I guess you’d
have to have a standard.
What?
I was going to
say you’d have to have a certain type of water.
