Misconceptions About States and Changes of Matter

Students may think…	Instead of thinking…
When water boils and bubbles, the bubbles are air, oxygen or hydrogen, or heat.	Bubbles formed by boiling water consist of water vapor (steam).
Steam is hot air.	Steam is water vapor.
When steam is no longer visible it becomes air.	When water vapor condenses in the air it is visible as tiny water droplets.
Water in an open container is absorbed by the container, disappears, changes into air, or dries up and goes into the air.	Water in an open container evaporates, changing from a liquid to a gas.
Ice molecules are colder than water molecules.	Ice molecules have less kinetic energy than water molecules.
Condensation is when air turns into a liquid.	Condensation is water vapor in the air that cools enough to become a liquid.
Condensation on the outside of a container is water that seeped (or sweated) through the walls of the container.	Condensation of water vapor happens when the water vapor in air comes in contact with a cool surface.
Expansion of matter is due to the expansion of the particles rather than increased space between the particles.	Matter expands when heated because the molecules are vibrating more quickly, loosening bonds, and increasing the space between adjacent atoms or molecules.
The water cycle involves freezing and melting of water.	The water cycle involves evaporation of liquid water, condensation of water vapor, and precipitation (rain, sleet, hail, or snow).
Water only gets evaporated from the ocean or lakes.	Water can evaporate from plants, animals, puddles, and the ground in addition to bodies of water.
The water cycle only includes rain and snow.	Ice in all its forms (sea ice, glaciers, ice sheets, icebergs, permafrost) is part of the global water cycle.

2.       pelajar membahagikan tugas yang perlu dilaksanakan di dalam projek

3.       pelajar meminta kebenaran daripada pengetua sekolah bagi memohon sumbangan bahan-bahan kitar semula (botol,tin, kertas) daripada para guru dan pelajar yang diperoleh dari sekitar sekolah

4.       Pelajar mula mengumpul dan mengelaskan bahan-bahan kitar semula daripada para guru dan pelajar.

5.       Pelajar menjalankan projek kraftangan daripada bahan-bahan kitar semula.

PELAKSANAAN PROJEK

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
