This is the organizational page for the Physics Introductory Labs portion of PHY 121 for Fall 2024.

The scope of the introductory labs is to give an understanding of basic experimental methods applied in physical sciences. The experiments performed during the lab sessions are closely related to the topics covered in the lecture.

Over the semester you will perform ten (10) experiments as indicated in the Manuals and Course Schedule section. You have 1 hr 50 min time to complete the measurements, by yourself or with a lab partner. Each experiment will come with a manual that you can access below.

For each lab, your perfomance will be evaluated by your teaching assistant based on the following components (left-click the blue bar to expand):

Grading for each experiment (left click to expand)

The pre-lab quiz will always be due on the same day that the lab is performed. All other components will generally be due by the start of the subsequent lab class, with possible exceptions to be specified by your TA.

Reports are to be done individually (including data collection - you and your partner should independently record all data). Although collaboration is allowed, your work should be your own. Work that is duplicated between reports will be punished severely.

Your final score will be an average from your ten lab grades (all ten, none dropped) scaled by a factor that will be determined at the end of the semester. This final lab score will contribute 25% to your grade in PHY 121. You will receive a single final grade for PHY 121.

The first lab sessions will take place in the week starting from Tuesday, September 5

Due Dates

You are responsible for keeping track of deadlines for your lab reports. The list of Due Dates (and return dates for work) is for reference only. Be alert to announcements on Brightspace and from your TA; these are official and supersede this list.

Late Work

New for Fall 2024: Late lab report penalty is double points off for one day late, triple for 2 days late, etcetera, up to 5 days. Then will not be considered and will receive zero points.

Exceptions for partial credit may be granted by a TA or the course instructor, with suitably documented reasons.

Absence and Make-Ups

If you need to be absent for a lab experiment you will have to provide written documentation for a significant reason to be absent, e.g., a medical note from your doctor or a written document about jury duty.

With such documentation, you will have the opportunity to make up the lab experiment in the dedicated make-up week. Under such circumstances, please submit a make-up request via the PHY121 Make-Up Request Form.

PHY 121 Course Policy

If you are absent for a non-excusable reason your lab grade for that particular experiment will be Zero (0) points! If you are absent for a non-excusable reason for more than three labs you will fail PHY 121. See the course syllabus for details.

There are three ways to ask questions or report problems:

• To contact your TA, use the e-mail addresses provided at the top of this page. This is the best option for lab-specific questions, such as checking requirements.
• To contact all TAs, use PHY121_lab@stonybrook.edu. This is the best option for general physics questions. If you cannot get in touch with your own TA and have a question on how to do a calculation (or why numbers look weird), this is also a reasonable place to contact.
• For administrative concerns, contact the course instructor, Richard Lefferts, at phy_introlabs@stonybrook.edu or in Office Hours, 1-3pm Thursday, in the Help Room
