Additional Material from LR Portal DAILY LESSON LOG Vito C. Pechangco Sr. Memorial National High School ROBERT G. ARQUERO October 28, 2019 Grade Level Learning Area Quarter 8 Science Four The learners demonstrate an understanding of how cells divide to produce new cells and how meiosis as one of the processes producing genetic variations of the Mendelian Pattern of Inheritance. The learners should be able to report on the importance of variation in plant and animal breeding. Compare mitosis and meiosis, and their role in the cell-division cycle. Identify the stages of mitosis. Describe each stage of mitosis. Explain the significance of mitosis.

Elicit In order to activate the students’ schemas regarding the lesson, the teacher will facilitate an interactive game entitled “Deal or No Deal”. The teacher will choose four students from the class to hold the question in front. He is going to select students to answer the question. A certain student will determine whether the statement is fact or bluff. If the statement conveys correct idea, the student must say “Deal!”. However, if the statement conveys incorrect idea, the learner should state “No Deal!”.

DEAL Statement Two Kinetochore serves as an attachment of the spindle fibers. DEAL Statement Three During anaphase, the chromosomes align themselves at the metaphase plate. NO DEAL Statement Four Prophase, metaphase, anaphase, and telophase are the stages of mitosis. DEAL B. Engage Skits will be performed in this segment of the lesson. The educator will post situations on the board, then the students are going to create a skit regarding that.

Explain In order the students can make connections and interconnections between the lesson and real life experiences, a brainstorming and a talk show regarding the stages of mitosis will be conducted. This particular segment of a lesson consists of two phases. Phase 1 is brainstorming, while the talk show is the phase 2. At the anterior part of this activity, the teacher will divide the class into six groups. Each group has an assigned concept to be deliberated and discussed with their group mates for few minutes. Afterwards, the educator serves as the host of the said talk show. In addition, he will also choose one learner from each group who will serve as the resource person/guest speaker. Phase 1: Brainstorming First Group MITOSIS Laptop Speaker Projector PowerPoint Presentation Background Music Second Group Stage 1: PROPHASE Third Group Stage 2: METAPHASE Fourth Group Stage 3: ANAPHASE Fifth Group Stage 4: TELOPHASE Sixth Group IMPORTANCE OF MITOSIS Phase 2: TALK SHOW The talk show dramatizes the exploration of the literature. Because students are generally familiar with the format, talk shows are particularly engaging form of reader’s theatre, or minimalist classroom theatre in which the students write and perform skits based on the literature they are studying. In creating a talk show, the students interpret characters, conflicts, themes, and issues for a live audience on a classroom stage. To create a talk show some students role-play key characters from one or several texts, while other students role-play interviewers or reporters. In this activity, teachers will host, directing the flow of questions and answers among characters and reporters. (Enclosure 1: Analytic Rubric for the Talk Show) Guide Questions: Explain mitosis. What are the important events during prophase? During metaphase, what does the chromosome do? Describe anaphase. What are the important events during telophase? Why does mitosis important? E. Elaborate HUMAN TABLEAU Manila Paper To consolidate what has been learned and to make it relevant to the life of every learner, an activity entitled “Frozen Act” will be conducted. The teacher will group the class into three. Then, he will ask each group to act/show the importance of mitosis in a silent and frozen manner. Every will be given 20 seconds to conceptualize it. Afterwards, the teacher will select one student from each to explain the output regarding the significance of mitosis (growth and development and repair of damaged tissues). Cartolina In this activity, students create a still picture, without talking, to capture and communicate the meaning of a concept. Students must truly understand the meaning of a concept or idea in order to communicate it using physical poses, gestures, and facial expressions rather than words. This collaborative strategy is appealing to kinaesthetic learners and allows all students to be creative while strengthening their comprehension of concept.
