Detailed lesson plan in chemistry

  1. 1. DETAILED LESSON PLAN IN CHEMISTRY I. OBJECTIVES: At the end of the lesson, the students should be able to: A. Discuss the difference between physical and chemical change; B. Appreciate the importance of the knowledge on physical and chemical change in our life through citing its applications in our community; and C. Write at least 5 examples of chemical and physical changes of matter. II. SUBJECT MATTER: A. Topic: Changes of Matter B. Materials and References: *Candle, matchstick, paper, pentel pen, Manila paper, *Visual Aids – Graphic Organizers *http://chemistry.tutorvista.com/physical-chemistry/physical-and- chemical-changes.html *http://www.kentchemistry.com/links/matter/physicalchemicalchange s.htm C. Science Concepts: Physical Change- is a change which occurs in size, shape, color, texture, state, magnetic or electrical condition but the molecular composition remains totally unaltered. Chemical Change- a change during which the molecular composition gets totally altered, that is change in which a new product is always formed. D. Process Skills: Defining, Differentiating, Appreciating, Observing, Critical Thinking E. Value Integration: Inquisitive mind and cooperation during the teaching-learning process F. Teaching Strategies: Inquiry Approach, Discussion, Audio Visual Presentation
  2. 2. III. DEVELOPMENTAL TASK: Teacher’s Activity Teacher’s Activity Prayer Greeting Checking of Attendance A. Review Last meeting, we learned about matter and its classification. So as a sort of review, what is matter? Very good! What are the three classification of matter? Correct! What is the difference between solid and liquid? Very good! What is the difference between solid and gas? Very true! Now, how can we distinguish that a matter is a gas? Exactly! Student’s Activity Matter is anything that occupies space and has mass. The three classification of matter are solid, liquid and gas. The difference between solid and liquid is that Solid has a definite shape and volume while Liquid has a definite volume and assumes the shape of the container. The difference between solid and gas is that Solid has a definite shape and volume while Gas has no definite shape. We can distinguish that the matter is a gas by its particles due to that the particles of gases are far from each other.
  3. 3. So, is there any question regarding our previous lesson? B. Motivation Class, I have here a piece of paper and a candle with a matchstick. All you have to do is to tear the paper into small pieces and burn the candle through a matchstick. I need two volunteers from the class. After you had performed the activity, try to explain what happened to the piece of paper and to the candle. Those who are on their sits, try to observe your classmate’s work. C. Presentation This afternoon, we are going to relate what you have observed from your classmate’s work. Based from the activity that your classmates have done, what will be our topic for this afternoon? Very good! This afternoon, we are going to discuss the two changes of matter – the physical and chemical change. 1. Discussion Class, do you have any idea what physical change is? You have the idea! None, Sir. (The students volunteer to do the activity) Changes of Matter, Sir. Physical change is a change in the form of matter but not in its identity.
  4. 4. Another, yes Gener? Very good! How about chemical change? Definitely! Class, I have here a melting ice and a dissolved sugar in water. What changes are taking place in these two examples? How can you say that these two examples undergo physical change? Exactly! I also have here another example – a rusting nail and a spoiling food. What changes do these two examples undergo? Why these two examples undergo chemical change? Very Good! Now, who can compare physical from chemical change? Physical Change is a change which occurs in size, shape, color, texture, state, magnetic or electrical condition but the molecular composition remains totally unaltered. Chemical change is a change in which one kind of matter is changed into a different type of matter. Physical change is taking place in those examples, Sir. The two examples undergo physical change due to that it remains the same and there is no new product that is being formed. The two examples undergo chemical change, Sir. Those two examples undergo chemical change because there is a change in its chemical properties, Sir. Physical change is a change in an object’s physical properties such as
  5. 5. Absolutely! Is there any question regarding our topic for this afternoon? 2. Activity Proper Class, we will have an activity in relation to our topic for this afternoon. I will divide the class into two groups. Those who are sitting on the left side will be the group 1 and those on the right side will be the group 2. You select a leader, a secretary and reporter. Your group leader will get your materials in for the activity. Afterwards, discuss your work to the class. (Activity sheets are attached at the back) 3. Post Activity (Students discuss their work on the board) IV. GENERALIZATION Based on the activity that you had performed, who can now discuss the difference between physical and chemical change? size, shape, color, texture, state, etc. while Chemical change is a change in which a new product is formed. None, Sir. Physical change is a change in an object’s physical properties such as size, shape, color, texture, state, magnetic or electrical condition but the molecular composition remains totally unaltered. Some examples of physical change are breaking of a glass, separating sand from gravel, and cutting woods. On the other hand, chemical change is a change during which the molecular
  6. 6. Who among you here can give other examples of physical and chemical changes of matter that are happening in your community? Therefore, how important is these physical and chemical changes of matter into our community? V. EVALUATION: ½ Crosswise Direction: Do what is indicated. 1. What is a physical change? Give at least 5 examples. 2. What is a chemical change? Give at least 5 examples. 3. Differentiate chemical from physical change. composition gets totally altered, that is change in which a new product is always formed. Some examples of chemical change are digesting foods, frying an egg, and burning of leaves. There are some of the physical and chemical changes in our environment. These are as follows: a rusting bicycle, bleaching your hair, hammering wood together to build a house, combustion of fuel, heating of zinc oxide and freezing of water. These are really important due to that we apply these physical and chemical changes in our daily living.
