Local sections participate in Chemists Celebrate Earth Week 2025

On April 20–26, American Chemical Society volunteers from 92 local sections, two international chemical sciences chapters, and several student chapters hosted hands-on activities and demonstrations for the 2025 Chemists Celebrate Earth Week (CCEW).CCEW is an ACS outreach program that promotes the positive role that chemistry plays in the world. This year’s theme was “Glaciers: Hot Topic, Cool Chemistry.” During a week of programs, thousands of members of the public learned about the chemistry of glaciers and why the United Nations has designated 2025 as the International Year of Glaciers' Preservation.“CCEW 2025 was a resounding success. By raising awareness about these frozen reservoirs, we not only highlighted their beauty but also their critical importance as sources of fresh water and in providing stability for global ecosystems,” says Keith M. Krise, chair of the ACS Committee on Community Activities, which coordinates CCEW in collaboration with the ACS Office of Science Outreach. Below are some highlights from the CCEW 2025 celebrations:The California Section conducted a full day of hands-on science for visitors during Earth Day celebrations at the John Muir National Historic Site in Martinez. Attendees learned about glaciers, icebergs, sea level rise, and the rate of ice melting in warm versus cold water. Children also made ultraviolet-detecting bracelets and identified plant fragrances.The Central Utah Local Section held an outreach event for children with hands-on glacier-related activities at a local library. It also organized a seminar on trace metals in glaciers.The Central Wisconsin Local Section distributed issues of Celebrating Chemistry magazine to University of Wisconsin–Stevens Point
