Backwards Planning Lessons
Carol-Ann Dennis – Backward Planning Lessons 1-4 – Week 3
Title of Lesson 1: What is a chemical reaction?
Grade Levels: 7th grade
Standard: MS – PS1-2. – Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. (examples = burning sugar or steel wool, fat reacting with sodium hydroxide, and mixing zinc with hydrogen chloride).
Objectives: Students will be introduced to chemical reactions, reactants, and products and will build upon their knowledge of chemical versus physical changes.
Essential Questions: How is a chemical change related to a chemical reaction?
Estimated Time: 50 minutes
Materials: Steel wool, lighter, Triple-Bean Balance, Google Chromebooks, Science Interactive Journals
6E Learning Cycle Stages
Engage: Wearing goggles with the student’s only viewing, the steel wool will be weighed on the Triple-Beam Balance to begin with and students will record the weight in their Science Interactive Journals. The teacher will light the steel wool on fire, which reduces the steel wool’s weight since the materials are being oxidized into the air as ash. Following the demonstration the steel wool will be weighed again and students will record the data once again.
Explore Through E-search: Students will search on the internet for other examples of chemical reactions and even find a video of the reaction that they just saw.
Explain: Students will be asked to continue in their Science Interactive Journal explaining why the steel wool weighed less after the burning of it.
Extend: Students would be asked to journal a fact that they already knew before class, a fact that they learned today, and an answer to the essential question.
Literacy Component: Students could create their own chemical reaction and explain how it would work, even in an imaginary world. They would need to explain the change and how the reactants are different from
