Bookshelf-Please Staple
 Chemistry of Living Things Booklet
Was due yesterday

2. BIOChemical VIRTUAL LAB
TERMINOLOGY – CORNELL NOTES

3. Highlight
Scientists use experiments to search for cause and
effect relationships. In other words, they design an
experiment so that changes to one item cause
something else to change in a predictable way.
These changing variables can be identified as
independent, dependent and controlled. We as scientist
focus our observations on the dependent variable to
see how it responds to the change made to the
independent variable.

6. Virtual Lab
How does the European Corn Borer
affect the yeild of corn?
Since we know that the ECBs loves to
eat corn…what are the farmers afraid
of in terms of corn yield?
Kernel mass per each ear of corn=
“weighing” the total amount of corn
kernels produced by one ear of corn.

7. Hypothesis
Based on what you know about the
experiment…..
If we test four different types
of corn under similar
conditions and change only
the infestation level, then we
should be able to determine
and give evidence for which
corn type will provide the

• There are 8 different data collection tests.
• Continue until all Data is Collected.

9. TODAY’S TASK LIST
1) Work with a partner from your table OR
individually.
2) Pick up your Assigned Computer.
3)You will be held responsible for its well-
being.
4) Ask Clarifying Questions as needed.
5)Begin experiments & collection of data
6) Our Goal is complete 8 tests by the
middle of class tomorrow.

10. HOMEWORK
1)Test #3 Corrections due tomorrow.
2)We will be working in class on the
Virtual Lab tomorrow and we will
collaborate our conclusions on
Friday.
3)This lab is not due by Monday of
next week.
