About this resource

Synthesis, Decomposition, and Combustion Reactions - Senior Chemistry Lesson

Your lesson covers three main reaction types. In order, the lesson teaches; the Steps to Writing Reactions, Synthesis Reactions, Decomposition Reactions, and Combustion Reactions.

Your lesson includes the teacher and student version of the presentation, TWO embedded videos, an auto-graded exit ticket, and a student lesson handout so the students can record the notes on a more condensed medium.

This lesson is designed to be your go-to resource, whether you're in a traditional classroom or a virtual one. With both a teacher version and a student version, it seamlessly fits into your lesson plans, making learning engaging and adaptable.

Assessment made easy

We've included an auto-graded Exit Ticket and a quiz with an answer key because I know you don't have an excess of time. I know you don't, because I don't and I know I'll do whatever I can to reduce my grading time.

Whether you use PowerPoint or Google Slides, prefer Word or Google Docs, this lesson has you covered. This lesson comes in both Office and Google formats for your convenience.

The student version of the presentation has strategically placed blanks for them to fill in as you're teaching. It keeps them active and engaged, encourages discussion, and leaves more time for those "aha" moments.
