LESSON PLAN IN GRADE 10 SCIENCE
CONTENT STANDARD: The learners demonstrate an understanding of the structure of
biomolecules which are made up mostly of a limited number of elements such as Carbon,
Hydrogen, Oxygen and Nitrogen.
PERFORMANCE STANDARD: None
LEARNING COMPETENCY: Learners should be able recognize the major categories of
biomolecules such as Carbohydrates, Lipids, Proteins and Nucleic acids.
I.
Learning objectives:
After the discussion, at least 80% of the students will be able to:
1. Identify the major categories of biomolecules such as carbohydrates, lipids,
proteins and nucleic acids.
2. Differentiate the biomolecules from each other in terms of their structure
and function.
II.
Subject Matter: Major categories of Biomolecules
A. Concepts
1. Carbohydrates – they are molecules made from aldehydes and ketones
containing numerous hydroxyl groups.
2. Lipids – they are water insoluble molecules that are composed of carbon,
hydrogen and oxygen.
3. Proteins – they are found as structural materials in hair, nail and
connective tissue.
4. Nucleic acids - Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA)
are nucleic acids.
B. Materials: Pictures, paper, pen, worksheets, Lab apparatus
C. References: Science Learners’ material, 1st ed. by Herma D. Acosta, et. al.,
pp. 443-471
Science Teachers Guide, 1st ed. by Herma D. Acosta, et. al.,
pp. 314-324
D. Process skills: Comparing, Analyzing, Determining, investigate
E. Values Integration: Appreciate the vital role of biomolecules which are
essential to life.
III.
