Join Librarian JoSep for a charged challenge and learn the properties of static electricity. Gather a balloon, a SFPL Library Card, small pieces of paper, string, and wool fabric.

Live STEM Lab with SFPL is created by the STEM Challenge Yo’Self Youth Librarian team. Bring your questions and share your work.

Stay STEM-tastic by reading, learning and experimenting at home. Gather materials for a new challenge posted weekly on Mondays at 2pm. Then, register for a Live STEM Lab with SFPL on Tuesdays at 2pm.
