The Royal Society of Chemistry has created this most useful website to help teachers and students of chemistry learn about the field via interactive experiments, diagrams, animations, and so on (UK 2012).

Interactive encyclopedia (USA 2017)

Resources for high school chemistry teachers, Classroom Teaching Resources to Education Standards to Professional Development (The American Chemistry Society (ACS 2016).

Lesson Plans and more (USA: American Chemical Society 2017)

The Concept Builders on this site are interactive questioning modules that present learners with carefully crafted questions that target various aspects of a concept. First launched in 1996, The Physics Classroom is the creation of Tom Henderson, a physics and chemistry teacher at Glenbrook South High School in Glenview, Illinois (2019).

Organic chemistry textbook, divided into the two overarching topics of General Principles and Functional Group Reactions, by William H. Reusch, emeritus professor at Michigan State University (2016)

Resources for educators related to chemistry, many of which come from the National Science Digital Library (USA 2014).

Collection of experiments that demonstrate a wide range of chemical concepts and processes (Nuffield Foundation, USA 2012)

The goal of these materials is to answer the question: what should one actually do to make chemistry “green” or “greener?” (American Chemical Society 2012-20)
