No-prep needed! PPT, practice worksheet, exit ticket, video clip, visual examples, and check for understanding questions! I am confident you will find this a valuable resource!
This lesson is a great introduction to physical changes. I start off by having students brainstorm every possible way that they can change a piece of notebook paper and still have it be paper. After a couple of minutes I take volunteers (you would be surprised with how creative their answers can be). The following slide shows a picture of a flame and I ask how this is different from the things they listed. This gets us into the topic of physical changes and how in a physical change no new substance is created.
There are a lot of visuals in this PPT that help students (especially ELLs) grasp this concept. Ex: Solid gold --> liquid gold --> solid gold.
I end with pictures of various things (melting chocolate, burning wood, etc) and have students put up a 1 for physical change and a 2 if it is not a physical change. Students then practice with a worksheet independently or with a partner before ending the lesson with a 5-question exit ticket!
Clear and to the point. I promise this will make your life easier!
