Matter and Substances by using Mastery Model

MATTER AND SUBSTANCES

Changes in the State of Matter

By using Mastery Model

 Determine the Learning Outcome

At the end of this topic, student will be able to:

·         Explain the kinetic theory of matter

·         Relate changes in heat to changes in kinetic energy of the particles in matter

·         Explain the interconversion of the three states of matter based on the kinetic theory of matter

Carry out teaching and Learning Process

1.  Teacher will introduced the three state of matter with the aid of diagram to trigger the prior knowledge of the students.                                                                                                        
2. Teacher will explain the kinetic theory of matter by using power point presentation.                      (refer to appendix 1)
3.  In order to give better understanding to the students, teacher will show a video about the changes in kinetic energy of the particles in matter during heat change, changes in the state of matter involving the absorption or release of heat and changes in matter during melting, boiling, condensation, freezing and sublimation based on the kinetic theory of matter.

 Assessment/ Evaluation

Teacher will give a set of question regarding the topic discussed in order to test the student’s understanding.

Intermediate Students   
Since the objectives were not achieved, so the teacher will provide the other methods and tools about same topic during the next session to make them easy to understand.                         
 Excellent Students

While handling the intermediate students, teacher will give reinforcement exercise and the teacher will give them problem and ask them to solve in small group.

Activity for intermediate

Provide game for them to practice

Activity for excellent students

Question 1

Mary has two containers of the same size. She fills up container A with marbles and container B with water as shown below.

(a) What will happen when Mary pours all the water from container B into container A?

Proceed to Unit 2

As all students achieved the first objective, then teacher will proceed to the next subtopic.
