1. Starter: 94 93 Law of Conservation of Mass Lab 11/04/2015 Application/ Connection/Exit : Conservation of Mass Lab 11/04/2015 Law of Conservation of Mass Lab “ What is proven by balancing equations?” Practice: Review Variables IV: D: C: EQ: How do chemical reactions obey the law of conservation of mass?

2. Starter “ What is proven by balancing equations?” That matter is not created or destroyed, only changed into something new or different

3. November 4, 2015 AGENDA 8.5 F. I will be able to recognize whether a chemical equation containing coefficients is balanced or not and how that relates to the law of conservation of mass by reading, and writing while completing notes and a lab. 1 Starter 2. Lab

5. Variables- Anything that can change or be changed in an experiment. Practice

6. Independent variable- the variable that YOU, the experimenter, change.

7. Dependent Variable- the variable that you are measuring, that may change when you change the independent variable.

8. Constants( Or Control) All other variables must remain the SAME in order for the experiment to be valid.

9. Application/ Connection/Exit You will work with your table partners to complete the lab. ( groups 3-4 students) Please read before starting and create your hypothesis. Follow all steps and answer questions as you go. DO NOT PLAY AROUND WITH MATERIALS. Lab is due at end of class.
