INTRODUCTION
       This Handbook aims to provide the general public – parents, students, researchers, and other stakeholders
– an overview of the Mathematics program at the secondary level. Those in education, however, may use it as a
reference for implementing the 2002 secondary education curriculum, or as a source document to inform policy
and guide practice.


       For quick reference, the Handbook is outlined as follows:


       •   The description defines the focus and the emphasis of the learning area as well as the language of
           instruction used.


       •   The unit credit indicates the number of units assigned to a learning area computed on a 40-minute per
           unit credit basis and which shall be used to evaluate a student’s promotion to the next year level.


       •   The time allotment specifies the number of minutes allocated to a learning area on a daily (or weekly,
           as the case may be) basis.


       •   The expectancies refer to the general competencies that the learners are expected to demonstrate at
           the end of each year level.


       •   The scope and sequence outlines the content, or the coverage of the learning area in terms of concepts
           or themes, as the case may be.


       •   The suggested strategies are those that are typically employed to develop the content, build skills, and
           integrate learning.

       •   The materials include those that have been approved for classroom use. The application of information
           and communication technology is encouraged, where available.


       •   The grading system specifies how learning outcomes shall be evaluated and the aspects of student
           performance which shall be rated.


       •   The learning competencies are the knowledge, skills, attitudes and values that the students are
           expected to develop or acquire during the teaching-learning situations.


       •   Lastly, sample lesson plans are provided to illustrate the mode of integration, where appropriate, the
           application of life skills and higher order thinking skills, the valuing process and the differentiated
           activities to address the learning needs of students.
The Handbook is designed as a practical guide and is not intended to structure the operationalization of the
curriculum or impose restrictions on how the curriculum shall be implemented. Decisions on how best to teach
and how learning outcomes can be achieved most successfully rest with the school principals and teachers. They
know the direction they need to take and how best to get there.
DESCRIPTION
The Science Program at the secondary level is designed to promote students’ awareness of the relevance of science
in life and develop critical and creative thinking as well as skills in problem solving through the teaching of
science in an outdoor environment and cooperative learning. More than the understanding of science concepts,
emphasis is given on the application of these concepts to improve the environment and the quality of life.


In First Year, Integrated Science builds on elementary Science, and weaves together bits of earth science, biology,
chemistry and physics which flow sequentially in a more unified and meaningful pattern of study.


In Second Year, the learners focus on Biology, which deals with the living world of human and non-human
                                        Biology
species, human interactions and relationships with the environment, and the problems we face relative to health,
reproduction and heredity, food production, resource management and conservation.


In Third Year, the learners focus on Chemistry, which deals with the properties and chemical behavior of matter,
                                     Chemistry
atomic structure, chemical changes, and technology affecting the environment and society.
UNIT CREDIT
Science in all year levels shall be given 1.5 units each.




TIME ALLOTMENT
       Science offerings in all year levels are allotted 60 minutes (1 hour) daily.
EXPECTANCIES
The learner is expected to apply scientific knowledge, skills and values in identifying and solving problems of the
environment, its conservation and in evolving better ways and means of doing things in daily living.




                                                CHEMISTRY
At the end of the Third Year Science Program, the learner should be able to demonstrate understanding of the
science concepts in chemistry; develop skills to know the structure, composition, properties and classification
of matter and to explain different chemical processes/reactions, changes in matter/energy and its applications to
daily life and a discriminating appreciation of technology.




                                                  BIOLOGY
         At the end of the Second Year Science Program, the learner should be able to explain the interrelationship
between the different biological processes; demonstrate scientific skill with competence and confidence; initiate
activities in the preservation and conservation of the environment.




                                       INTEGRATED SCIENCE
        At the end of the First Year Science Program, the learner should be able to demonstrate understanding of
basic science concepts, skills and attitudes needed to explore biology, chemistry, physics and earth science with
an integrative understanding and application of these scientific disciplines .

          1. Enumerate the factors affecting rates of chemical reactions;
          2. Explain how each factor affects the rate of chemical reactions; and
          3. Relate the value of working for our goals in life to the lesson.


II. Subject Matter

         A. Topic
            Factors Affecting Rates of Chemical Reactions


         B. References

III. Learning Tasks

         a.     Recall
               We learned from the past lesson that chemical system a chemical system either release or absorb
               energy. When do we say energy is released/absorbed in a chemical system?


         b. Motivation
            How fast can a reaction go? We say some are very fast, others are very slow. There are many
            reasons that may affect rates of reaction. Can you name some?


         C. Lesson Proper
            1.     Activity
                  1.1     Effect of temperature
                          Measure two 1 – gram sample of rock salt. Put each gram separately in small
                          beaker. Pour 10 mL of tap water in one beaker and add 10 mL of hot water in the
                          other. Observe the time it takes to dissolve each sample of salt.


                     1.2     Effect of Particle size
                             Measure one gram of rock salt. Put this on a small beaker. Measure one gram of
                             granulated salt. Put this also in another small beaker. Pour 10 mL of tap water into
                             each beaker. Compare the rate of dissolving of solids in the beaker.
1.3    Effect of concentration
            Measure 10 mL of 3 M HCl and put this into a small beaker. Measure the same
            amount of 6 M HCl and put it in a different beaker. Measure 2 inches of Mg ribbon
            and roll this to make it compact. Add the 2 inch rolled Mg ribbon into each of the
            beakers simultaneously. Observe the reaction.


     1.4    Effect of catalyst (DEMO only)
            Measure 20 mL of Hydrogen Peroxide. Put this in a small beaker. Put a very
            small amount of Manganese dioxide in a spatula. Using a spoon with a long handle,
            (deflagrating spoon) drop the Mg ribbon to the beaker with Hydrogen Peroxide.
            Observe how fast the reaction occurs.


            Caution: Use goggles. Move as far back as possible from the reaction set up before
            mixing the reactants.


     1.5    Nature of Reactants
            Get 0.5 grams of NaCl. Stir this in a small beaker with 20 mL of water. Get another
            0.5 grams of the salt and stir this in 20 mL of Ethyl Alcohol. Compare the results.


2.   Post lab activity
     Reaction rate is defined in terms of the disappearance of one of the reactants or it may be
     defined as the rate of appearance of one of the products.


     In our activity, we have observed that rate of reactions vary. Let us discuss the various
     factors
     2.1      Effect of temperature
             According to the Kinetic Molecular Theory, the kinetic energy of molecules
             increases as the temperature increases. Increased kinetic energy increases the speed
            of particles, thus increased molecular collision takes place. Increased molecular
            action results in increased molecular activation energy, thus lowering activation
            energy level.
     2.2    Effect particle size
            Smaller particles are more reactive. They are more energetic. Small particles have
            greater surface area exposed to reaction, thus increasing the frequency at which
            particles collide.
     2.3    Effect of concentration
            The greater the number of reacting substances increases the rate of reaction.
            Crowded particles in a fixed volume increase the frequency of collision.
     2.4    Effect of catalyst
            A catalyst is a substance that increases the rate of reaction without itself being
used in the process. Catalysts act in one or more steps of reactions by lowering the
                            reaction energy level. With lower activation energy level more collision will have
                            sufficient energy to pass over the energy barrier. Thus, greater fraction of collision
                            is effective at any given point.
                    2.5     Nature of reactant
                            Ionic reactions occur almost instaneously. NaCl is highly soluble in another polar
                            substance like water. This system demonstrate the “like dissolves like” reaction.
                            In this system the oppositely charge collide, more often, thus causing effective
                            reaction.


             3.     Generalization
                    There are 5 general factors affecting the rate of reaction; temperature, concentration,
                    particles size, potency of catalyst and nature reactants. The rate of reaction depends upon
                    the rate of effective collision, which are dependent upon the energy reactant particles
                    and the barriers of the reaction. Therefore, reactions rate is made faster by: increasing
                    temperature, increasing concentration, reducing the number of reactants or of similar
                    nature e.g. polar to polar or non-polar to non-polar.


             4.     Valuing/Application
                    All of us have goals in life. We would wish to achieve these goals as best we can and at the
                    soonest. To be successful, we look for ways we can overcome possible obstacle. Sometimes,
                    we need the influences of other people. When we do ask for other peoples help, we see to it
                    that they understand our situation in life.


             5.     Evaluation
                    1.    How are each of the following concepts relate with the rate of reaction?
                           a.    frequency of collisions
                           b.    kinetic energy of collisions
                            c.      orientation of colliding particles


                    2.      How is the activation energy affected by the presence of catalyst


IV.    Agreement
             In the past lessons, we determined the various factors that effect reaction rates. In our next lesson,
             we shall try see how these learning’s are applied in common things we do in life. For example:


      1. How do we preserve or prolong the life of food?
      2. What happens during digestion?

    3. Generalization:
       a.    According to the Kinetic Molecular Theory of Matter, the phase of a given sample of
             matter is determined by existing temperature and pressure.
       b.    Refrigeration cycle is a continuous change of phase/ state, temperature, and pressure
              inside the major components of the refrigerator.


    4. Valuing:
              Phase changes continuously occur in the environment. The water cycle consists of phase
       changes like evaporation that helps in maintaining a fairly comfortable temperature range in
       the atmosphere and condensation, which produces rain that washes the atmosphere of gaseous
       pollutants. Life sprouts from the interaction of the soil, air, and water in the environment.

  • 3. INTRODUCTION This Handbook aims to provide the general public – parents, students, researchers, and other stakeholders – an overview of the Mathematics program at the secondary level. Those in education, however, may use it as a reference for implementing the 2002 secondary education curriculum, or as a source document to inform policy and guide practice. For quick reference, the Handbook is outlined as follows: • The description defines the focus and the emphasis of the learning area as well as the language of instruction used. • The unit credit indicates the number of units assigned to a learning area computed on a 40-minute per unit credit basis and which shall be used to evaluate a student’s promotion to the next year level. • The time allotment specifies the number of minutes allocated to a learning area on a daily (or weekly, as the case may be) basis. • The expectancies refer to the general competencies that the learners are expected to demonstrate at the end of each year level. • The scope and sequence outlines the content, or the coverage of the learning area in terms of concepts or themes, as the case may be. • The suggested strategies are those that are typically employed to develop the content, build skills, and integrate learning. • The materials include those that have been approved for classroom use. The application of information and communication technology is encouraged, where available. • The grading system specifies how learning outcomes shall be evaluated and the aspects of student performance which shall be rated. • The learning competencies are the knowledge, skills, attitudes and values that the students are expected to develop or acquire during the teaching-learning situations. • Lastly, sample lesson plans are provided to illustrate the mode of integration, where appropriate, the application of life skills and higher order thinking skills, the valuing process and the differentiated activities to address the learning needs of students.
  • 4. The Handbook is designed as a practical guide and is not intended to structure the operationalization of the curriculum or impose restrictions on how the curriculum shall be implemented. Decisions on how best to teach and how learning outcomes can be achieved most successfully rest with the school principals and teachers. They know the direction they need to take and how best to get there.
  • 5. DESCRIPTION The Science Program at the secondary level is designed to promote students’ awareness of the relevance of science in life and develop critical and creative thinking as well as skills in problem solving through the teaching of science in an outdoor environment and cooperative learning. More than the understanding of science concepts, emphasis is given on the application of these concepts to improve the environment and the quality of life. In First Year, Integrated Science builds on elementary Science, and weaves together bits of earth science, biology, chemistry and physics which flow sequentially in a more unified and meaningful pattern of study. In Second Year, the learners focus on Biology, which deals with the living world of human and non-human Biology species, human interactions and relationships with the environment, and the problems we face relative to health, reproduction and heredity, food production, resource management and conservation. In Third Year, the learners focus on Chemistry, which deals with the properties and chemical behavior of matter, Chemistry atomic structure, chemical changes, and technology affecting the environment and society.
  • 6. UNIT CREDIT Science in all year levels shall be given 1.5 units each. TIME ALLOTMENT Science offerings in all year levels are allotted 60 minutes (1 hour) daily.
  • 7. EXPECTANCIES The learner is expected to apply scientific knowledge, skills and values in identifying and solving problems of the environment, its conservation and in evolving better ways and means of doing things in daily living. CHEMISTRY At the end of the Third Year Science Program, the learner should be able to demonstrate understanding of the science concepts in chemistry; develop skills to know the structure, composition, properties and classification of matter and to explain different chemical processes/reactions, changes in matter/energy and its applications to daily life and a discriminating appreciation of technology. BIOLOGY At the end of the Second Year Science Program, the learner should be able to explain the interrelationship between the different biological processes; demonstrate scientific skill with competence and confidence; initiate activities in the preservation and conservation of the environment.

Recall We learned from the past lesson that chemical system a chemical system either release or absorb energy. When do we say energy is released/absorbed in a chemical system? b. Motivation How fast can a reaction go? We say some are very fast, others are very slow. There are many reasons that may affect rates of reaction. Can you name some? C. Lesson Proper 1. Activity 1.1 Effect of temperature Measure two 1 – gram sample of rock salt. Put each gram separately in small beaker. Pour 10 mL of tap water in one beaker and add 10 mL of hot water in the other. Observe the time it takes to dissolve each sample of salt. 1.2 Effect of Particle size Measure one gram of rock salt. Put this on a small beaker. Measure one gram of granulated salt. Put this also in another small beaker. Pour 10 mL of tap water into each beaker. Compare the rate of dissolving of solids in the beaker.
  • 49. 1.3 Effect of concentration Measure 10 mL of 3 M HCl and put this into a small beaker. Measure the same amount of 6 M HCl and put it in a different beaker. Measure 2 inches of Mg ribbon and roll this to make it compact. Add the 2 inch rolled Mg ribbon into each of the beakers simultaneously. Observe the reaction. 1.4 Effect of catalyst (DEMO only) Measure 20 mL of Hydrogen Peroxide. Put this in a small beaker. Put a very small amount of Manganese dioxide in a spatula. Using a spoon with a long handle, (deflagrating spoon) drop the Mg ribbon to the beaker with Hydrogen Peroxide. Observe how fast the reaction occurs. Caution: Use goggles. Move as far back as possible from the reaction set up before mixing the reactants. 1.5 Nature of Reactants Get 0.5 grams of NaCl. Stir this in a small beaker with 20 mL of water. Get another 0.5 grams of the salt and stir this in 20 mL of Ethyl Alcohol. Compare the results. 2. Post lab activity Reaction rate is defined in terms of the disappearance of one of the reactants or it may be defined as the rate of appearance of one of the products. In our activity, we have observed that rate of reactions vary. Let us discuss the various factors 2.1 Effect of temperature According to the Kinetic Molecular Theory, the kinetic energy of molecules increases as the temperature increases. Increased kinetic energy increases the speed of particles, thus increased molecular collision takes place. Increased molecular action results in increased molecular activation energy, thus lowering activation energy level. 2.2 Effect particle size Smaller particles are more reactive. They are more energetic. Small particles have greater surface area exposed to reaction, thus increasing the frequency at which particles collide. 2.3 Effect of concentration The greater the number of reacting substances increases the rate of reaction. Crowded particles in a fixed volume increase the frequency of collision. 2.4 Effect of catalyst A catalyst is a substance that increases the rate of reaction without itself being
  • 50. used in the process. Catalysts act in one or more steps of reactions by lowering the reaction energy level. With lower activation energy level more collision will have sufficient energy to pass over the energy barrier. Thus, greater fraction of collision is effective at any given point. 2.5 Nature of reactant Ionic reactions occur almost instaneously. NaCl is highly soluble in another polar substance like water. This system demonstrate the “like dissolves like” reaction. In this system the oppositely charge collide, more often, thus causing effective reaction. 3. Generalization There are 5 general factors affecting the rate of reaction; temperature, concentration, particles size, potency of catalyst and nature reactants. The rate of reaction depends upon the rate of effective collision, which are dependent upon the energy reactant particles and the barriers of the reaction. Therefore, reactions rate is made faster by: increasing temperature, increasing concentration, reducing the number of reactants or of similar nature e.g. polar to polar or non-polar to non-polar. 4. Valuing/Application All of us have goals in life. We would wish to achieve these goals as best we can and at the soonest. To be successful, we look for ways we can overcome possible obstacle. Sometimes, we need the influences of other people. When we do ask for other peoples help, we see to it that they understand our situation in life. 5. Evaluation 1. How are each of the following concepts relate with the rate of reaction? a. frequency of collisions b. kinetic energy of collisions c. orientation of colliding particles 2. How is the activation energy affected by the presence of catalyst IV. Agreement In the past lessons, we determined the various factors that effect reaction rates. In our next lesson, we shall try see how these learning’s are applied in common things we do in life. For example: 1. How do we preserve or prolong the life of food? 2. What happens during digestion?
