Chemists Celebrate Earth Week is an annual event that coincides with Earth Day and celebrates the importance and positive impact of chemistry on our planet. This year, it is held from April 16-22 with a topical focus on “The Curious Chemistry of Amazing Algae.”

In celebration of this event, ACS Publications invites you to explore various resources on chemistry, algae, and the natural world across our portfolio of journals. From educational tools to cutting-edge articles and Virtual Issues, we hope you enjoy learning about the fascinating properties of algae and its benefits for our environment and long-term sustainability.

"Chemists Celebrate Earth Week: The Curious Chemistry of Amazing Algae" - A Virtual Issue

Algae are emerging as one of the most promising long-term, sustainable sources of food, biofuels, bioplastics, and other co-products. What makes them so attractive are the large number and wide variety of benefits associated with how and where they grow. Nearly all these benefits stem from the fact that algae have evolved over billions of years to produce and store energy, and they do this more efficiently than any other known natural or engineered process.

This Virtual Issue brings together recent articles from ACS journals highlighting discoveries, advances, and novel applications of algae across diverse fields and industries.

Educational Resources and Tools from the Journal of Chemical Education

To help celebrate Earth Week 2023, the Journal of Chemical Education offers a wealth of resources for exploring algae and its applications in both chemistry and nature. Through the articles and experiments listed below, students can examine the properties and uses of algae, including investigating algal biodiesel and experimenting with alginate biopolymers. With 100 volumes of interesting material on a wide variety of topics, it is easy to connect the classroom experience to the greater world through the Journal of Chemical Education.

Expand each section below to access resources from the journal and learn all about the fascinating world of algae!
