Lesson Plan in Science Grade 10

Time Frame: 60 minutes Competency Code: S10MT- IVC-d-22 Learning Competency: Recognize the major categories of biomolecules such as carbohydrates, lipids, proteins, and nucleic acid.


Objectives At the end of sixty minutes, the students will be able to: 1. Identify the major classes of Biomolecules; 2. Classify the different biomolecules according to their category; and 3. Give the importance of biomolecules in our daily lives

Subject Matter: A. B. C. D. E.

Topic: Biomolecules Strategies: Comprehension and Conceptual Understanding Materials: marker , adhesive tape , cartolina References: Grade 10 – Science Learner’s Material pages 443-446 Values: Enhance communication skills of the students, class participation and cooperation

F. Science Concepts/ Key Concepts: 1. Biomolecules- are large molecules that are needed in life.

Major classes of biomolecules a. Carbohydrates- is a very important source of energy b. Proteins - are the building blocks of life. c. Lipids- better known as fats d. Nucleic Acids - are very large and complex organic molecules that contain the genetic code. 2. Monomer is a building block that makes up a substance. II.

Development of the Lesson a. Preliminaries 1. Classroom Management 2. Prayer 3. Greetings 4. Attendance b. Review/Recap The students will have a review on the previous topic. The students will be asked the following questions: 1. What are the types of chemical reaction? 2. What are the evidences of chemical reaction? 3. Give an example of a substance that undergoes chemical reaction. 

Motivation Students will be given chocolates and they will identify the ingredients. The students will be asked about their feelings after eating the chocolate.


Presentation of the Lesson A. Activity Activity Title: Picture Analysis Materials:

  

Set of pictures Adhesive tape Manila paper

Procedure: 1. The class will be divided into four (4) groups. 2. The facilitator will give each group a set of pictures and manila paper. 3. The students will classify the set of pictures according to carbohydrates, proteins, lipids, and nucleic acids which was written on the manila paper. 4. They will be given only 3 minutes to do the task, after that they will post it on the board. 5. One representative will justify their answer on the class.

Rubrics Areas to Assess




5 All members of the group cooperates in the activity All pictures are classified accordingly The output was posted ahead of time

3 Some members of the group cooperate in the activity Some pictures are classified accordingly The output was posted on time

1 Few members group coopera the activity

Most of the pic are classifie inappropriat The output po past the tim required.

B. Analysis The students will be asked the following questions: Why did you classify the pictures in the carbohydrates? So how do you define carbohydrates in your own understanding? How about proteins? Lipids? and nucleic acids? Do you think the pictures fit in this category? Which do you think is/are not included in this category?

C. Abstraction What are Biomolecules? Biomolecules are large molecules that are needed in life. 1. Each group will be given 3 varied strips of paper about the elements, functions, and monomers of the four classes of biomolecules. 2. They will be given only 3 minutes to brainstorm of what specific biomolecules does each strip belongs base on its composition, function and types of monomer. 3. A group representative will post the 3 strips of paper based on what the group has agreed.




Nucleic Acids





1. Energy production 2. Energy storage

1.Great source of long term energy 2. Great for insulating through blubber/fat

1. Protein helps prevent infection and diseases. 2. Repair and maintenance

1. carries genetic information in the cell

D. Application Nutrients are essential to life, these are the substances needed by our bodies for growth and development. Regular consumption of the right amount of these substances can keep our bodies in good health. In order for us to be able to track our consumption of these nutrients, commercial

products put “nutrition facts” embedded on their labels so that consumers will have an idea of the contents they are taking in. On the other hand, too much, and improper consumption of these nutrients may lead to health problems such as obesity, osteoporosis, diabetes, gout, and heart disease.

E. Generalization Biomolecules are important as they control almost every aspect of organisms. Carbohydrates provide the body with source of fuel and energy. Proteins provide structural support and also defense against germs and infections. Lipids in body are used as energy storage they are very important for they make up all animal cells. Lastly, nucleic acid carries genetic information in the cell.

F. Evaluation Matching Type: Write the letter of the correct answer on the space provided. A B

____1. Biomolecules ____2. Proteins ____3.Nucleic Acids ____4.Carbohydrate s ____5. Lipids ____6. Pasta ____7. seafoods ____8. Egg ____9. Butter ____10. Obesity

a. great fast source of energy; made up of monosaccharide b.large molecules that are needed in life; are the building components of life. c.known as fats; great for insulating d.carries genetic information in the cell e.made up of amino acids, great for muscle building f.Proteins g.Nucleic Acids h.Carbohydrates i.Lipids j. too much lipids k.too much carbohydrates


Assignment On a ½ sheet of paper, identify the three (3) basic classifications of carbohydrates and give two examples each.
