Happy Spring 2023!

Happy 2023! Welcome to the spring semester at UMD Physics!

The Physics Lecture-Demonstration Facility is here to fulfill your classroom demonstration needs this semester. We’re looking forward to an exciting semester!

Be sure to explore our new online resources as well, including the demonstration videos channel, LecDem blog, and the directory of simulations. Keep an eye out for new material to come!

If you have any questions about finding the right demonstrations or other resources for your class, access to the order form, or anything else we can help with, be sure to call or email.

Please remember to order your demonstrations before the cutoff deadline for the order form system: For morning classes, before 1PM the previous working day; for afternoon classes, before 4AM the day of the class. Where possible, we appreciate having the orders at least one full working day ahead, to ensure plenty of time to make sure everything is ready for you.

We have many events coming up this spring, including Physics is Phun, Physics Discovery Day, and Maryland Day; watch our website for news!
