Extra Credit Project
The
Life of a Plant
One plant will be given to each student to take care of as an extra credit project for the semester.
Journalizing:
1. Keep a journal that records
the growth, flowering, and (hopefully not) the death of your plant.
2. The longer you keep your
plant alive this semester, the better your journal project will turn out.
If you hand in a journal that simply states ‘plant died’, then you will
not get 10 points for the
journal.
3. Be creative! Some
suggestions for your journal notebook:
a. use a permanently bound notebook as your journal.
b. use loose-leaf paper gathered by a plastic report cover.
c. use the creative ‘scrap booking’ style and make your own notebook!
d. your imagination is the limit! Have Fun!
4. Use color pencils, color
prints, or color photographs to document your plant's progress.
Accurate Observations:
1. Keen observation is the
key to successful science explorations. Twice a week, observe your
plant and make notes on plant characteristics such as differences in height
(how tall is your plant at
day 8…day 10 etc.), leaf shape (what different leaf shapes occur), leaf
color, and number of flowers (if any).
2. To organize your data,
you can set up a small spreadsheet table recording some of the potential
changes in these plant characteristics.
3. Make notes on potential
problems you encounter (yellowing leaves, wilting, insect attack…. etc)
and solutions you tried to reverse these life threatening problems.
4. Did any of the solutions
tried actually reverse the problem? Even if there are no apparent problems,
is there some change that may make the plant grow better? Try it.
5. Be sure to incorporate
pictures, drawings or graphs to clarify observations described in the text
of your journal.
Communicating your observations:
1. Written explanation is
essential. Make sure you write your observations or findings in your
journal along with any pictures or tables that you might have.
Extra Credit Grade Points:
1. 5 points of extra credit
will be available on each exam from questions pertaining to your plant.
2. Another 10 points of
extra credit will be based upon the quality and accuracy of your final
plant journal project.
3. All
completed journals are due in class on the last day of classes
(May 13th).
4. See syllabus for course
grade details.

What's in a name?
Botanical
dictionary- look up the Latin names of the plant- why were they chosen?
Hint- if a whole word does not produce a hit, use parts of the word - the
parts are often linked together to describe the plant. The first word in
the latin name is the genus- so
the description would apply to the group of plants to which this plant
is very closely related. The species name is the second name,
so this word would be chosen to describe this plant in particular (
Some
examples ,
more
here where you don't have to search). Some species are named after
the person who officially discovered the plant (e.g. Tolmiea, see
below).
See if there is a common name for the plant in different languages:
