- 1. GRADE 9 DAILY LESSON LOG School: STA. CRUZ NHS Grade Level: GRADE 11 Teacher: SYLVIA C. ENONG Learning Area: PHYSICAL SCIENCE Teaching Dates and Time: January 14-18 2019 Quarter: FOURTH MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY I. OBJECTIVES A. Content Standards The learners demonstrate an understanding of -The following aspects of chemical change: a. How fast a reaction takes place. b. How much reactants is needed and how products are formed in the reaction. c. How energy is involved in the reaction. B. Performance Standards C. Learning Competencies The learner should be able to use the simple collision theory to explain the effects of concentration, temperature, and particle size on the rate of reaction. (S11/12PS-IIIf-23), Define catalyst and describe how it affects reaction rate. (S11/12PS-IIIf-24), Calculate the amount of substances used or produced in a chemical reaction. (S11/12PS-IIIf-h-25) D. Sub-Task/s Conduct Item analysis for Third Quarter Exam. Remediation for those who got poor grade. Give remedial exam and completion of the requirements for the Third Quarter. 1. Define chemical reaction and identify its parts. 2. Describe activation energy and explain its role to chemical reaction. 3. Appreciate the effect of chemical changes in our lives. 1. Identify the factors that affect chemical reaction. 2. Explain how those factors affect chemical reaction through simple collision theory. 3. Awareness on the effect of the rate of chemical reaction. Quiz about Chemical reaction and factors Affecting the reaction rate. II. CONTENT HOW CHEMICAL CHANGES TAKES PLACE How Fast Reaction Takes Place A. References 1. Teacher’s Guide Pages N/A N/A 2.

Other Learning Resources Visual aids, laptop for PPT presentation Visual aids, laptop IV. PROCEDURES A. ELICIT Asks the students about their prior knowledge about chemical changes that occurs in the environment. (Asks) What are some chemical changes that you have observed in the environment? What is chemical reaction? What is the energy required to undergo chemical reaction? B. ENGAGE Show a picture of a barbed wire being rusted. (Asks) What do you think happen to the barbed wire? How does it occur? What kind of reaction occur? Which is faster to dissolve in water, the tablet medicine or the powdered on? (Focus the students that seize of the reactants have great effect in chemical reaction.)
- 3. C. EXPLORE Let the students perform the activity: Understanding Chemical Reaction. Rubrics: Criteria Percentage Accuracy 40% cooperation 20% Presentation 40% Total 100% Let the students perform the activity:Factors that affect chemical reaction. Grouping them into 3 groups. Rubrics: Criteria Percentage Accuracy 40% cooperation 20% Presentation 40% Total 100% D. EXPLAIN Group work presentation. Let the students present their works to the class. Power point presentation of Chemical reaction.. Guide questions: 1. What is Chemical reaction? 2. What is the energy required to undergo chemical reaction? 3. Illustrate activation energy and its role to chemical reaction. Group work presentation/Post lab discussion. Let each group present their works to the class. Guide question? 1. How does the concentration of the reactants(G1), Temperature (G2) and particle size (G3) affect the chemical reaction? 2. Explain the effect of your given factor to the rate of chemical reaction based on simple collision theory.
- 4. E.ELABORATE -What is chemical reaction? -How does chemical reaction occur? -What energy is required to undergo chemical reaction? (Show a power point presentation about Chemical reaction for further understanding.) --How does chemical changes affects your lives? Power point presentation about how different factors, such as concentration, temperature and particle size affect the chemical reaction. Explain further how those factor affect the reaction rate through simple collision theory. -Some reaction occur very fast due to some factor, how can you show your awareness to this cause? F. EVALUATE Answer the following questions correctly. 1. Define chemical reaction and identify its parts. 2. Explain how activation energy works in chemical reaction. 3. Illustrate a diagram showing activation energy. Answer the following in 1/4 sheet of paper. 1. What are the factors that affect reaction rate? 2. Explain how each factor affect the rate of chemical reaction based on collision theory. G. EXTEND What are the different factors that affect chemical reactions? A. List down at least 5 chemical reaction that you observed in the environment. B. Be ready for the quiz tomorrow about Chemical reaction. V. REMARKS 80 % of students grasps the lesson.
- 5. VI. REFLECTION A. Additional activities for application or remediation V. REMARKS VI. REFLECTION Reflect on your teaching and assess yourself as a teacher. Think about your student’s progress this week. What works? What else needs to be done to help the students help your instructional supervisors can provide for you so when you meet them, you can ask them relevant questions. A. No. of learners who earned 80% on the formative assessment. B. No. of learners who require additional activities for remediation. C. Did the remedial lessons work? No. of learners who have caught up it the lesson. ____Yes _____No No.of Learners who have caught up with the lesson. ____Yes ____No No. of Learners who have caught up with the lesson D. No. of learners who continue to require remediation. E. Which of my teaching strategies worked well? Why did these work?
