During the second semester
physics students will participate in an investigative electronics circuit
project. The primary objective
of this project is to investigate the behavior, including the independent
variable and dependent variable of the RC time
constant in audio or LED electronic circuits. The initial,
completed circuit and its' performance is the control. The parts that control
the time constant are the "if" (independent variable)
and the resulting change in the RC time constant is the "then" (dependent
variable). Students are provided with a list of projects and each
group of two students selects one project.
Laboratory investigation
Dates: May 4, 2010 to May 13/14, 2010
This project will involve two
grades:
1. Laboratory grade: Five lab grades
ranging from a maximum of 10 to 30 points will be awarded for required
entries to the journal. Any day that you do not have your journal,
lab points will be zero. Refer to the posted criteria in the journal grading
rubric link in the table below.
2. Journal (exam) grade: You
must keep a laboratory journal that contains detailed notes of the project.
It counts as a 100 point exam grade. Refer to posted criteria.
Journal
Due date: May 16, 2010
ABSENCES
If a student is absent during the project week,
it must be noted in the laboratory journal. The absent student will
receive a laboratory grade of zero until they have made up their work.
Make-up work must be done within 24 hours of the absence. The make-up
work can be done at home or at school, but a journal record is required.
A student who is absent three or more times during the project week will
be required to do a separate individual project. The teacher will
assign this project to the absent student.
