INTRODUCTIONThis 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 defi nes 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 specifi es 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 specifi es 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.

B. References

Chemistry by Merrill pp. 448-452Chemistry by Addison Wesley pp. 492-494

III. Learning Tasks

a. RecallWe 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. MotivationHow 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 Proper1. Activity

1.1 Effect of temperatureMeasure 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 sizeMeasure 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.

Page 49: BEC Science

1.3 Effect of concentrationMeasure 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, (defl agrating 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 ReactantsGet 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 activityReaction rate is defi ned in terms of the disappearance of one of the reactants or it may be defi ned 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 temperatureAccording 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 sizeSmaller 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 concentrationThe greater the number of reacting substances increases the rate of reaction. Crowded particles in a fi xed volume increase the frequency of collision.

2.4 Effect of catalystA 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 suffi cient energy to pass over the energy barrier. Thus, greater fraction of collision is effective at any given point.

2.5 Nature of reactantIonic 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. GeneralizationThere 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/ApplicationAll 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 infl uences of other people. When we do ask for other peoples help, we see to it that they understand our situation in life.

5. Evaluation1. How are each of the following concepts relate with the rate of reaction?

a. frequency of collisionsb. kinetic energy of collisionsc. orientation of colliding particles

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

IV. AgreementIn 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?

Phase Changes in Refrigeration Cycle

Science Concepts Technology Concepts• Evaporation is the process of changing Evaporation is the process of changing

a liquid into gas by increasing the temperature.

• The molecules of liquids with higher energies evaporate fi rst leaving behind those molecules with lower energies.

w The liquid refrigerant circulates inside the refrigerator absorbing heat from the foods, drinks, and air inside it.

w The evaporator increases the temperature of the refrigerant thus converting it into its gaseous phase.

w The pressure of a gas is directly proportional to its temperature.

• Temperature and pressure increase inside Temperature and pressure increase inside the compressor.

w Condensation is the process of changing a gas to liquid.

w Removing heat from a sample slows down the movement of the molecules.

w The condenser changes the vaporized refrigerant into its liquid phase by removing heat from it and releasing such heat outside the refrigerator.

w Lowering the temperature of a liquid slows down the movement of the molecules thus decreasing the pressuredecreasing the pressure

After the liquid refrigerant passes through the expansion valve, the pressure decreases with simultaneously decrease in temperature simultaneously decrease in temperature

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.
