Finally we completed a lab on physical properties and chemical reactions. The purpose of the lab is for students to look for the "signs of the chemical reactions". The signs they are looking for color change, precipitate formation, gas formation, and heat formation. Here are the lab conclusion questions:
•Choose any FOUR real life examples of a chemical changes. Indicate the signs of the chemical change in that example.
•Explain the difference between a chemical and physical change, including an example.
