Describe the importance of Photosynthesis for life on Earth
for 8th Grade (Botany)
is one of the most basic life processes on earth. It may have
been one of the characterisitics of some early life to evolve.
Understanding how photosynthesis impacts the rest of life
on the planet is important to understanding the global ecology of
today. The majority of organisms the conduct photosynthesis
reside in the ocean and are not trees.
Using what you already know about climate chemistry and the
websites listed below; I want you to offer a prediction as to the consequences
if the Earth suddenly had twice as many photosynthesizing organisms. What would happen if the Earth had only half
as many photosynthesizing organisms?
Construct your predictions as a short essay.
visit the websites to gain any insights that you can in relatin to
input and outputs then construct your essay and provide a defense of
your predictions (the predictions don't have to be correct, just well
construct your essay try looking at photosynthesis in terms of input
and output and then imagine it on a massive, global scale.
This is where you list a few web sites, include some images, and
ask some very specific questions students are supposed to answer by
visiting the sites.
Describe to the
learners how their performance will be evaluated. Specify
whether there will be a common grade for group work vs.
Objective or Performance
Discussion does not include key elements of photosyntesis
Key elememts identified but not placed in a logical sequence.
Identify key elements in a logical sequence of reactions and how they relate to the Earth
Identify key elements in a logical sequence of reactions and how they relate to the Earth and relate to the geological record.
this exercise has given you the oportunity to consider how some
of the most simple and common biological processes can have
consequences on the geological and global scale.
