  Republic of the Philippines DEPARTMENT OF EDUCATION Instructional Planning (iPlan) (With inclusion of the provisions of D.O. No. 8, s. 2015 and D.O. No. 42, s. 2016) DETAILED LESSON PLAN (DLP) DLP No.:   Learning Area:   Grade Level:   Quarter:   Duration:   Q1W3-D3 Matter    7   1st   60 minutes  1. LEARNING COMPETENCY Investigate properties of saturated and unsaturated solutions Code (S7MT-Ic-2)  Key Concepts/ Understanding to be Developed What is the Evidence that a Solution is Saturated? Specific Learning Objectives Knowledge Identify the types of solution  Skills Investigate when a solution becomes saturated and unsaturated  Attitudes Follow procedure in an investigation Values Carefulness in performing activity 2. CONTENT 3. LEARNING RESOURCES References Learners Manual Science 7 pp 9-11 ; TG Science 7  Materials white sugar, water, measuring cup (1cup capacity), measuring spoon (½ tsp capacity), clear, transparent bottle, stirrers or plastic spoons, and thermometer 4. PROCEDURES 4.1 Introductory Activity The teacher will show a picture to the students. The students will be instructed to observe the picture, afterwards the students will answer the following questions below; 1.   How will you differentiate the three images in the picture? 2.   Do you consider the three images in the picture to be a solution? 3.   Why do you consider the images in the picture to be a solution? 4.   What are the types of solution? 4.2 Activity With their teammates, the students will investigate when a solution  becomes saturated and unsaturated using the different materials which they bring. Refer in the activity sheet on the next page. 4.3 Analysis These questions will be asked to the students: What happened when you’ve stirred the sugar into the water? How many teaspoons of sugar have you added until the sugar no longer dissolves? So, how many teaspoons of sugar dissolved completely in 20 mL of water? 4.4 Abstraction What is the difference between saturated solution from unsaturated solution? 4.5 Application How would you apply the idea on saturated and unsaturated solutions at home? How will you dissolve the excess solutes in a saturated solution? 4.6 Assessment The output of the students will be assessed based on the following: a. Correctness of the response- 25 pts.  b. Completeness- 15 pts. c. Teamwork and Neatness- 10 pts. 4.7 Assignment The students will be tasked to bring the materials needed for the next activity. Materials:    chocolate powder     plastic cups    teaspoon, stirrer    rock salt, water (hot and cold)     sugar     powdered coffee 4.8 Concluding Activity 5. REMARKS  Indicate below special cases including but not limited to continuation of lesson plan to the following day in case of re-teaching or lack of time, transfer of lesson to the  following day, in cases of classes suspension, etc. 6. REFLECTIONS  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 learn?  Identify what help your instructional supervisors can provide for you so when you meet them, you can ask them relevant questions. Indicate below whichever is/are appropriate.  A. No. of learners who earned 80% in the evaluation.  B. No. of learners who require additional activities for remediation. C. Did the remedial lessons work? No. of learners who have caught up with the lesson.  D. No. learners who continue to require remediation.  E. Which of my learning  strategies worked well? Why did these work?  F. What difficulties did I encounter which my  principal or supervisor can help me solve? G. What innovation or localized materials did I use/discover which I wish to share with other teachers? Prepared by: Name of Teacher: School: Position: Division: Contact Number: Email Address:   Name: ____________________________________ Gr. & Sec.: _____________ Date: _______________ Group No.: ________ Rating: __________ Investigative Activity 3 What is the Evidence that a Solution is Saturated? Objectives: After performing this activity, you will be able to: 1. determine how much solid solute completely dissolves in a given volume of water; and 2. describe the appearance of a saturated solution. Materials Needed: 6 teaspoons white sugar 1 measuring spoon (1/2 tsp. capacity) 1 cup of water 1 clear, transparent cup 1 measuring cup 1 plastic spoon Procedure: 1. Put 20 mL (approximately 2 tablespoons) of water in a small clear transparent cup. Add ½ teaspoon of sugar and stir. Q1. What is the appearance of the solution? Write your observations.______________________________________________________________________  __________________________________________________________. 2. To the sugar solution in step # 1, add ½ teaspoon of sugar, a small portion at a time and stir the solution to dissolve the sugar. At this point, you have added 1 teaspoon sugar. 3. Add ½ teaspoon of sugar to the sugar solution in step #2 and stir the solution. At this point, you have added one and ½ teaspoons of sugar. 4. Continue adding ½ teaspoon sugar to the same cup until the added sugar no longer dissolves. Q2. How many teaspoons of sugar have you added until the sugar no longer dissolves?  __________teaspoons Note:  In this step, you will observe that there is already excess sugar which did not dissolve. Q3. So, how many teaspoons of sugar dissolved completely in 20 mL of water?  ____________teaspoons Note:  This is now the maximum amount of sugar that will completely dissolve in 20 mL of water.
