NO-PREP! 24-slide PPT, practice worksheet, exit ticket, embedded video clips, and guided practice questions!
This PPT deals with the differences between physical and chemical changes. Ultimately, having students learn 5 pieces of evidence that suggest a chemical change occurs.
1. Gas production
2. Unexpected color change
3. Formation of a precipitate
4. Odor change
5. Energy release
I start of with an embedded YouTube clip. This is a 90 second clip from the movie Wreck It Ralph. I have students watch the clip and jot down examples in the clip that they think represent a physical change and examples that they think represent a chemical change.
Students then learn the definition of what a chemical change actually is and are shown another embedded clip of a chemical reaction and are required to write down everything they notice in the clip that they think proves it is a chemical change. The chemical reaction is REALLY cool.
Students move on to learning about the five pieces of evidence that suggest and chemical change occurred and take notes. Visuals are included for each piece of evidence. I end with common examples of chemical changes such as rusting, digesting, and baking. 4 check for understanding questions are included in the PPT!
