Students are to first look at the virtual lab form.
On the instructions page for the lab report is a printer icon to
view a printable version of the lab report.
This might be useful to jot down your observations as you are
retrieving the test results from the virtual lab.
Take a look at the Rubric page to see how you will be accessed.
When
you are ready to begin, go to the virtual lab page and begin your
analysis.
- Determine
from your reading why this analysis of feed and how it reacts in the
rumen environment is important. This
will be your purpose.
- Look
at all the different feed on the lab page available for you to
introduce to the rumen environment. The
choices include forages and concentrates. You
will test each feed for pH, Ammonia and Methane. Choose
at least 6 different feeds and make an educated guess or prediction
“hypothesis” of what the outcome of the different tests will be.
- Describe
the materials, procedures and steps.
- Make
observations on the different outcomes of each feed.
- Analyze
and compare the feeds against each other.
Explain what your data means. Interpret your data. Explain any
results that were not predicted.
- Finally,
in one or two sentences explain if your results agree or disagree with
your hypothesis
- Fill
out the online lab form and submit.
Print out the confirmation page and submit to you teacher.
- Finally,
after finishing the lab report, you
will submit a self-evaluation of your work by using the
self-evaluating rubric found on this site.
As
always, if you have any questions, please feel free to ask the instructor.
