ChemMatters is an educational magazine containing articles on topics for high school chemistry students. The articles explain the connection between what chemistry students learn in school and the world around them. ChemMatters is used by teachers as a complement to their textbook. I find it useful to support science literacy and make connections. I also use some of the articles for emergency sub plans or on days just before a vacation when I know that I will be missing many of my students. These articles can easily be read and the assignment completed outside of class for those students who are missing that day. Teachers can get a subscription to the magazine, but many of the articles are available for free download.
