    Grade 9 Total Count Vs Mass

    Uploaded by

    king devesfruto
    The lesson plan aims to teach students about the mole concept and molar mass. Students will analyze the relationship between the number and mass of different materials through an activity comparing samples with the same mass but different compositions. They will learn that while the number of particles may be the same, the masses will differ depending on the material. Students will complete tables to demonstrate their understanding of mole, atomic mass, molar mass, and Avogadro's number. The teacher will assess students' comprehension through questions about these key topics.

    I. Objectives:
    1. Content Standard: The learners demonstrate an understanding of…
     The unit, mole that quantitatively measures the number of very small particles of matter.

    2. Performance standard: The learners shall be able to:


     Analyze the percentage composition of different brands of two food products and
    decide on the products’ appropriate percentage composition.
    3. Learning Competencies/Objectives:
     Use the mole concept to express mass of substances. (S9MT-IIi19)
     Determine the percentage composition of a compound given its chemical formula and
    vice versa. (S9MT-IIj20)
    4. Specific objectives: The learners will be able to…
     Examine the relationship between the number of materials and their masses.
     Complete the table comparing the mass and number of materials.
    II. Subject Matter
    1. Topic : Total Count vs. Mass
    2. Reference : Teacher’s Guide
