Students can have an interesting “reaction” to chemistry. Okay, so maybe puns aren’t part of the chemistry curriculum, but issues of matter, nuclear structure, and yes, chemical reactions certainly are. Educators who want to teach chemistry at the secondary school level must take and pass the Praxis Chemistry: Content Knowledge (5245) Exam.
It’s an important test because many states use the results as part of the teaching certification process. The exam has several sections and, this guide walks you through what to expect. The guide also contains an excellent source for materials to help you prepare for the exam.
