Semi-detailed Lesson Plan in Science II

I. Objectives

At the end of the 30-minute discussion, students should be able to:

determine the different types of mutation; explain the differences among types of mutations; and speak out the importance of respecting persons with genetic disorders.

II. Subject Matter

Topic : Mutation

Reference : learngenetics.com

Materials : Powerpoint Presentation, Illustration Boards, Manila paper, markers

Value Infused : Respecting Persons With Genetic Disorders

III. Procedure

A. Routine Activities

1. Greetings

2. ClassroomManagement

3. Prayer

4. Food for Thought

5. Checking of Attendance

6. BioBits (Trivia of the Day)

B. Drill

Whose Comm. Is It?

The class will be divided into three (3) groups. Pictures of product commercials will be flashed on the screen and the students should be able to identify whose commercial is it. Answers will be written on the illustration boards provided. The group with the highest score wins the game.

Commercial Answer

Surf

Ponds Men

Fita

Lucky Me

McDonald’s

C. Review

- What is DNA?

- What carries the DNA?

- How many chromosomes does a normal human have?

D. Motivation

Pictures of McDo’s commercial showing a person with Down syndrome will be flashed on the screen, the students will be asked the following questions:

1. Are you familiar with his condition?2. How does the brother treat his sibling with Down syndrome?

The teacher will then present the objectives for the day.

E. Lesson Proper

Task 1: The teacher will present the chart for the students to identify the errors or mutations.

Mutation

What is mutation?

What is aneuploidy?

Task 2: After identifying the mutations, the teacher will ask the students to describe the sets of chromosomes in comparison with the normal sets.

Types of Aneuploidy

What is nullisomy?

What is monosomy?

What is trisomy?

What is tetrasomy?

Task 3: Images will be flashed on the screen and the teacher will ask the students some descriptions that they can easily note on the pictures.

Mutation in Humans

Down syndrome

What are the notable characteristics of a person with Down syndrome?

How do they act? Do they act according to their age?

Edward’s syndrome

What can you observe from the organs of the babies?

Monosomy 7

If the patients are having blood transfusions and low platelet counts, what do you think is the disease they suffer from?

Pallister-Killian syndrome

What can you observe from the foreheads of the two babies?

Special Question:

In humans, we have all types of aneuploidy except nullisomy, why do you think is that so?

F. Generalization

- What is mutation?

- What is aneuploidy?

- What are the types of mutation according to chromosome number?

- Being familiarized on how hard it is for persons with genetic disorders as well as the advancement of technology in which we can now be able to detect such disorders, will you favor euthanasia or mercy killing on babies with detected disorders for them not to suffer?

G. Application

Pass ‘N Roll

Mechanics: There will be a dice which will be drawn, the number will determine who will answer the question and what will be the question. An illustration board will be distributed among the groups, which will move according to the number on the dice drawn, for the students to write their answers. The group with the highest point wins.

1. Any change in an organism’s DNA

2. Any change in the normal number of chromosomes

3. Presence of an extra pair of chromosomes

4.The most common human mutation

5. Characterized by bone marrow insufficiency

6. Characterized by high foreheads
