Science at the Library – Chromatography and Forensic Science

How many colors make black? Be amazed as black magically turns into vibrant purples, blues, greens, magenta, and more with just a drop of water! This hands-on science activity for children 5 and older introduces the concept of chromatography. Chromatography comes from the Greek word chroma meaning "color" and graphia meaning "writing". Chromatography is a fun way to explore the separation of color pigments.

This program, held in conjunction with the One City One Book program and the Bay Area Science Festival, is limited to 20 participants. To reserve space, please call the children's librarian at (415) 355-5770 or email lkanno@sfpl.org
