The list of lesson plans shared here can be further refined by topic, practice, cross-cutting concept or disciplinary core idea.  They are free for teachers to access through the National Science Digital Library. 

PhET shares a series of interactives on different topics in chemistry. 

The Cornell Center for Materials Research provides a lending library of science experiments for teachers. Physics, earth science and chemistry kits (which include most materials required for the activities) can be borrowed and shipped to schools free of charge. This website also shares lesson plans and student activity sheets (in English and Spanish) available for download on a wide variety of science topics that have been or are being designed to meet the Next Generation Science Standards (www.nextgenscience.org). All grade levels. 

Ck12.org shares videos, simulations, practice quizzes and readings, many of which make real world connections to chemistry. They are organized by topic and can be accessed freely. 

Stuyvesant High School shares their chemistry pre-labs through a google site created for their students. Each pre-lab shares explanatory information along with a worksheet for students to complete. This link direct to the spring labs; use the menu at the top of the page for the fall set. 

Beyond Benign helps educators and students practice sustainability through chemistry by developing and sharing green chemistry and sustainable science resources. This link shares open-access curriculum – including over 200 lesson plans, units, and labs – focused on sustainable science, green chemistry and related subjects. The materials are designed by curriculum experts and linked to state and national standards. 

Click on a topic to see the materials offered on that topic. Then click “download lesson" to see the lab and the supports that go with it. All instructional resources are free to use; some link to science kits that can be purchased as well.

Ck12.org shares simulations for chemistry students. Teachers can filter this list to find resources on specific topics such as chemical bonding, oxidation, states of matter and more. 

These infographics take a look at the chemical compounds we come across in our daily life, and explain them with easy-to-understand graphics. These can be used to inspire questions and experiments with students. The Compound Interest site is maintained  by Andy Brunning, a chemistry educator based in Cambridge, UK. 

This blog shares a wealth of resources for teachers and students of chemistry including: labs, textbooks, and reviews (with handouts) on a variety of topics. The resources are free. This site is created and shared by chemistry teacher Ian Guch.

Chemtutor begins with the fundamentals and shares expert help with the most difficult phases of understanding a first course in chemistry.  Chemtutor can be used as a part of a course of study for independent students, a resource for chemistry teachers, a review, or a tutoring program for students taking high school or basic college chemistry. It supports the New York State curricula and provides support for AP Chemistry as well.
