Performance Standards II.CONTENT III.LEARNING RESOURCES Materials IV.PROCEDURES A. Reviewing previous lesson or presenting the new lesson. B. Establishing a purpose for the lesson. Grade Level: 7 Learning Area: Science and Technology Quarter: 1 Analyze the problems given. Solve problems related to the concentration of solution. Work on the problems with honesty and accuracy. The Learners demonstrate an understanding of some important properties of solutions. The Learners shall be able to prepare different concentrations of mixtures according to uses and availability of materials. Concentration of Solutions Science and Technology III: Chemistry Textbook.

Permanent marker pen, juice powder, water, plastic beaker, spoon, transparent plastic cups Show video clip on Solubility - YouTube (360p) Website: https://www.youtube.com/watch?v=JGkmGQ89_SE The teacher will demonstrate in front of the class following this procedure: Procedure (Part 1) 1. Label the clear, transparent plastic cups with numbers 1 to 4. 2. Place one spoon of powder juice in plastic cup #1. 3. Add 50 mL water to the juice powder in plastic cup #1 and stir the solution. 4. Place 2 spoons of juice powder in plastic cup #2. 5. Add 50 mL water to the juice powder in the plastic cup #2 and stir the solution. 6. Show the class plastic cup #1 and #2 and ask them to differentiate the two plastic cups. Procedure (Part 2) 1. Place one spoon of juice powder in plastic cup #3. 2. Add 20 mL water in plastic cup #3 and stir the solution. 3. Place two spoons of juice powder in plastic cup #4. 4. Add 100 mL water to the juice powder in the plastic cup#4 and stir the solution. 5. Show the class plastic cup #3 and #4 and ask them to differentiate the two plastic cups. After the demonstration, students should be aware that concentrated solutions can be prepared either by adding more solute and keeping the amount of solvent the same or keeping the amount of solute the same and reducing the amount of solvent. C. Presenting example /instances of the new lesson. D. Discussing the new concepts and practicing new skills #1. E. Discussing the new concepts and practicing new skills #2. F. Developing mastery G. Making generalization and abstraction about the lesson H. Finding practical application of concepts and skills in daily living. I. Evaluating learning. J. Additional activities for application or remediation V. REMARKS VI. REFLECTION A. No. of learners who earned 80% on the formative assessment B. No. of learners who Presenting an example of concentration of solutions that can be found at home. Present isopropyl alcohol and sachet of vinegar. Ask: How to describe the concentration of a solution? One can describe the concentration of a solution qualitatively or quantitatively through percent by mass or percent by volume. Show labels of alcohol and vinegar. Ask: What does 70% ethyl or isopropyl alcohol mean? 70% ethyl or isopropyl alcohol means the solution contains 70 mL alcohol. What does 5% acidity mean in the label of vinegar? Vinegar is often labeled as “5% acidity,” which means that it contains 5 grams of acetic acid in 100 g of vinegar. Stress out to the students that in solving for % by mass and % by volume, one must remember the correct formula. Percent by mass is the ratio of a measured mass of solute to a measured mass of solution. On the other hand, percent by volume usually describes solutions in which both solute and solvent are liquid. Ask: What to do if the mass or volume of solute and solvent are given but not the solution? Just add the mass or volume of solute to get the mass or volume of the solution. What to do when the mass or volume of the solvent and solute are given but not the solution? What is the difference between a concentrated solution from a diluted solution? How to solve for the percent by mass and percent by volume of a solution? Solve for the unknown. What is the percent by mass of NaHCO3in a solution containing 30 g NaHCO3 dissolved in 700 g of water? What is the percent by volume of ethanol in a solution that contains 55 mL of ethanol dissolved in 145 mL of water? What is the percent by mass of the solute sodium hypochlorite in a solution that contains 50 g of NaOCl dissolved in 2500 g of bleach solution. require additional activities for remediation C.
