Recommended strategy

1. Inform students of their background and the rewarding enrichment 
   class that they may partake in if they receive an 80% accuracy grade 
   on a test, which will be given after the demonstration and lecture.

2. Present the phenomena on chemical and physical changes in matter.  
  
3. Distribute Vocabulary Terms and Explanation sheet. Discuss each.

4. Review the phenomena and depict the chemical, physical, or both 
   change that occurred in each situation.  
 
5. Present pre-test on chemical and physical changes.  Orally grade
   test and discuss correct answers.

6. Present final test.  

7. After final test has been graded; inform those students who mastered 
   80% or higher when they will be taking the enrichment class.
          
8. Present a totally new lesson from a lower viewpoint to those 
   students who did not master 80%.  Also, allow more time in each 
   strategy for understanding and oral discussion.
