Students,
Please take a look at the Chemical and Physical Change Prezi below. You will learn what a chemical change is and how you might know that a chemical change has taken place. Also, you will learn what a physical change is and be introduced to 4 different examples of physical change. Please pay particular attention to how chemical and physical changes are different.
Has your bicycle chain ever rusted? Would this be an example of a physical or chemical change? How do you know?
If your bicycle tire loses air and goes flat, would this be an example of a physical change or chemical change? How would you know?
Please share your thoughts in the comments section below.
Lastly, before class tomorrow, go on a 'Chemical Change or Physical Change Scavenger Hunt'. Look for other examples of chemical and physical changes in your home and bring your ideas to class!
I can't wait to hear all of your great ideas!
