ChemEd DL seeks to provide exemplary resources for chemistry teachers and students—resources that are versatile and reliable tools that span all aspects of chemical education, from middle school science through college-level classes and topics. Our collection includes interactive simulations, tutorials, activities, reference materials, images, video and even more..


Resources at ChemEd DL are grouped into collections. Collections for different areas of chemistry (general, organic, physical), for various educational levels (K–12, higher education), for educational settings (laboratory, lecture classroom), and several others exist at ChemEd DL. We welcome additional collections and you are encouraged to suggest or even curate other chemistry collections.


Community: a feeling of fellowship with others as a result of sharing common attitudes, goals, and interests. ChemEd DL communities share the common interest of chemistry, the common goal of teaching or learning the chemical sciences, and the common attitude that chemistry is important to society.
