All labs are performed in TBE B-150.

The Teaching Assistants (TA’s) usually run the entire lab including:

 instruction, grading, and evaluation of student performance.

Contact the laboratory coordinator if there is a problem that cannot be

resolved directly between the student and the TA.

Individual Lab Reports & Homework:

• Follow the format guidelines found later in this manual and directions from the laboratory instructor.

• Printed copies of your report are due on the assigned due date.

• You cannot turn in a lab report if you did not attend and participate in the lab.

• Each lab report and homework assignment is graded with a maximum score of 100 pts.

• Late Reports:

o 10 points are deducted from your score for each week-day that the report is late.

o For example, you will lose 50 points if the report is 1 week late.

o Reports will not be accepted if they are more than 1 week late.

 

Group Lab Report:

• Each student will be a part of a group that plans and performs their own experiment.

• The lab TA must approve of all groups and projects before they are conducted.

 

Quizzes:

• Four closed book, short quizzes will be scheduled throughout the semester.

 

Attendance and Participation:

• The laboratory instructors will take attendance each week.

• They will also make note of enthusiastic participation, lack of participation, and/or leaving the lab early.

• They will assign a grade to each student at the end of the semester based on a combination of attendance and participation level in the class.

 

Excused Absences:

If you have a good reason to miss a lab, please contact your laboratory instructor ahead of time to make arrangements to make up the lab work.

 

All ME students must meet their faculty mentors at least once in each semester to avoid any hold in their registration. Please contact department for the name of the faculty mentor. When your faculty mentor is not available, you can contact ME Department for an advice.
