From April 16 to 22, American Chemical Society members from 96 local sections and four international chemical science chapters coordinated events for Chemists Celebrate Earth Week (CCEW).

This year’s theme was “The Curious Chemistry of Amazing Algae.” Thousands of people took part in hands-on activities or watched demonstrations at museums, parks, schools, libraries, and other public venues, as well as online.

“Our CCEW celebration this year has been a big success. Groups all over the world explored the chemistry of algae, including its properties as an edible and nutritious plant, and its role in providing food, habitat, and oxygen in a healthy ecosystem,” says Lori R. Stepan, chair of the Committee on Community Activities, which coordinates CCEW in collaboration with the ACS Office of Science Outreach.

Free CCEW resources provided by ACS include the magazine Celebrating Chemistry, published in English and Spanish. This year, 46,750 copies in English and 3,550 copies in Spanish were distributed. ACS also sponsored an illustrated poem contest for K–12 students.

The following are highlights of the 2023 celebrations:

The Binghamton Local Section partnered with Binghamton University to organize a booth with hands-on demonstrations at the annual Earth Day Festival in Recreation Park.

The California Section hosted booths at North Bay Science Discovery Day at the Sonoma County Fairgrounds and an Earth Day celebration at the John Muir National Historic Site.

The Central Wisconsin Local Section hosted a public talk about nitrate fertilizer and algae blooms by Kevin Masarik, a local groundwater education specialist.

The Chemical Society of Washington supported Rockville Science Day at Montgomery College. Approximately 100 exhibitors engaged more than 3,500 visitors in interactive science exhibits, games, and demonstrations.

The Eastern New York Section organized an event in the Armory Shed at Russell Sage College with demonstrations on algae’s uses and explanations of water testing analysis.

Volunteers from the Georgia Section organized about 20 hours of outreach activities on the chemistry of algae at the Fernbank Science Center and multiple K–12 institutions.

On behalf of the Green Mountain Local Section, two undergraduate students at Landmark College produced a 4 min video describing the differences between shelf-stable and refrigerated gel-based snacks. The students also created an in-person demonstration of the activity for a Chemistry of Magic class. The video was disseminated on social media platforms and to the college as a whole through the Daily Digest.

The Kansas City Section ran a Save Mother Earth afternoon in collaboration with teachers of grades K–6 at Pershing Elementary School. Students created solar cars and buggies and helped with gardening.

The Lehigh Valley Section and the Division of Environmental Chemistry coordinated an Earth Day Symposium for the public at Cedar Crest College. The section also hosted a community outreach event for about 75 children.

The Mark Twain Local Section organized a community cleanup with a local Scout group.

The Maryland Local Section held 13 1-hour, hands-on programs in public libraries in five Maryland counties.

The Mid-Hudson Section hosted an Earth Day hike at Clarence Fahnestock Memorial State Park. Participants trekked 4.5 miles while observing Thomas Edison’s field laboratories, iron mines, and newly sprung spring flora.

The Midland and Permian Basin Sections cosponsored an Earth Day Action Expo at Dow High School with around 60 exhibitors. ACS volunteers ran hands-on activities on photosynthetic pigments and the algae polymers alginate and carrageenan.

The Nashville Local Section and the Tennessee Tech University student chapter organized hands-on activities during Nashville Earth Day.

The New Jersey Section hosted an event at the Meadowlands Environment Center with demonstrations and activities on the chemistry of algae. Sue Lewicki, the center’s educator, also gave an interactive talk.

The New York Local Section coorganized a Chemists Celebrate Earth Week event at the Jones Beach Energy and Nature Center for over 100 attendees.

Northeastern Section coorganized an event with Salem University and the Museum of Science in which visitors participated in hands-on activities during the 2-day “Rise Up Boston: A Climate Event”.

The Northeastern Wisconsin Local Section held activity-station events on Earth Day at the Oshkosh Public Library, the Neenah Public Library, and the Atlas Science Center. Activities included making worms using sodium alginate and taking pictures of algae through microscopes.
