    This 3-sentence summary provides the key details about the document: This lesson plan outlines an activity to explain physical changes in water when heated or cooled by having students boil water and collect the condensation, with the objectives being to describe what happens to water particles during heating and cooling, perform the activity correctly, and cooperate with groupmates. The plan details the procedures of preparing materials, conducting pre-lab and post-lab discussions, and analyzing observations to conclude that boiling occurs when water molecules gain energy and escape as vapor which then condenses when cooled.

    Suggested Activities
    the Plan
    Awareness Have you tried boiling water in a kettle? What did you observe?
    Let us try to see in our activity today.

    Activity Check the materials brought by the students by group.


    Students do the activity (found in pp. 184- 186 of Science 8 LM ).
    A. Pre-laboratory discussion
    -Discuss the objectives and procedures.
    - Discuss the safety precautionary measures.
    B. Laboratory proper
    - Students perform the activity.
    - Students answer the guide questions.
    C. Post lab discussion
    -Discuss the results of the activity.
    - Checked the answers of the students.

    Analysis *What do you think is inside the bubbles that form when the water boils? Where did they
    come from?
    * What do you think will happen to the amount of water in the beaker if you keep the water
    boiling for more than 10 minutes?
    * What do you observe in the water inside the beaker and at the bottom of the watch glass.
    * Where does the water at the bottom of the watch glass come from?

    Abstraction As the water is heated and its temperature rises the molecules gain more kinetic energy and
    they move faster.More molecules have the energy to overcome the forces of attraction of the
    adjacent molecules.These molecules escape to the gaseous phase, the process is called
    boiling. The molecules that escape from the liquid and go into the gaseous phase is called
    vapor.The water vapor rises and some molecules touch the glass.The glass is cooler than the
    boiling water so some of the heat energy of the vapor molecules are transferred to the
    glass,in effect cooling the water vapor. As the water vapor began to cool,droplets formed
    under the watch glass that covered the beaker containing hot water, the process is called
    condensation.

    Application When you are cooking your food, where is boiling there? How about condensation?
    Solicit some examples from the students.
    Assessment 1. In boiling, what happen to the particles of liquid water?
    2. What happen to the particles of water during condensation?
