M.1 Science class. The teacher started the class through an oral reading of the weekly vocabularies. Then, a quick quiz about the previous topic followed to check students memory retention. Next, Mr. CJ had a brief recap of kinetic and potential energies to refresh students memory. Gradually, he linked the previous topics to the new one which is mechanical energy. Through this technique, students were able to connect the concepts of the new lesson to the previous ones. During the discussion, the teacher demonstrated each concept clearly. He provided lots of examples so that the learners could comprehend well. After the discussion, students hi-lighted, underlined the important terms to remember in their books and wrote short notes too. At the end of the lesson, students were encouraged to answer some questions about the new topic and some provided extra information too. Majority of the learners were alert during the discussion and showed interest to take part in the class activities.
