Join Librarian Kimberly for a rainy challenge and learn about the water cycle. Gather a jar, shaving cream, food coloring, water, a clear pitcher, 3 small bowls, and three eye droppers or 1/4 teaspoon measuring spoon.

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.
