For our introductory lesson of Unit 4, we revisited the concepts of physical and chemical change in the context of chemical reactions. The lesson began with a series of demonstrations. Students were tasked with recording observations and then determining whether a chemical or physical change had taken place.
Notes from class:
Next, students watched the following video from Mr. Anderson of Bozeman Science, with the expectation that they can clearly articulate the difference between a chemical and physical change by the end of the video.
After the video, we reviewed the vocabulary of chemical reactions (inputs/reactants and outputs/products) and then students had the remainder of the class period to complete the Lesson 70 Worksheet.
