Welcome to Fall 2025! We at the Lecture Demonstration Facility are looking forward to working with you in the spring semester.

We appreciate as much advance notice of demonstrations as you can give; but at a minimum, please remember to order your demonstrations before the order cutoff deadline.

• For morning classes, orders must be in before 1PM the previous working day.
• For afternoon classes, order must be in before 4AM the day of the class.

We appreciate receiving demo orders a minimum of one full working day ahead, to ensure plenty of time for preparation.  As always, we’ll meet with you before your class to answer questions, explain safety measures, and review demonstration procedures. 

Here’s to another great semester at UMD Physics!
