John Muir Birthday­ – Earth Day Celebration @ The John Muir National Historic Site
Apr 22 @ 10:00 pm – 4:00 pm

John Muir Association logo

Celebrating John Muir’s 185th birthday
the 53rd Anniversary of Earth Day
and the National Park Service Centennial
plus the 68th Anniversary of the John Muir Association 

Cal ACS will be there with hands-on chemistry, featuring the 2023 Earth Week theme,

“The Curious Chemistry Of Amazing Algae”

The California Section will join numerous other community and educational organizations for the return of this Earth Day celebration to Martinez.  Look for the Cal ACS canopy, where visitors will discover how algae make oxygen by splitting water using the power of sunlight.  They can also try splitting water by electrolysis, using electricity from photovoltaic panels.  And, they can make their own UV light-detecting bracelet using photochromic beads.

If you can help out at the ACS booth, please contact Sushila Kanodia.  See you there!
