Calendar

Cal ACS returns to the Alameda County Fairgrounds in Pleasanton, CA for some hands-on chemistry fun at the Tri-Valley Innovation Fair. We’ll join close to 100 other exhibitors as we welcome curious scientists of all ages.  They will learn about the 2025 Chemists Celebrate Earth Week theme, “Glaciers: Hot Topic, Cool Chemistry” as they observe the effect of glacier melting on sea level rise, and learn about the behavior of melting ice in fresh water versus salt water.  We’ll have plenty of Earth week souvenirs for them, including copies of Celebrating Chemistry (CCEW 2025 edition) and Periodic Table wallet cards.

As this is an all day event, we’re looking for additional volunteers take take a turn presenting these activities to our visitors.  If you’d like to join the fun, please contact Alex Madonik or Charlie Gluchoski!  We hope to see you there.
