INSTRUCTIONAL TECHNIQUES: Identification, explanation, playway method, questions and answers, demonstration, videos from source
INSTRUCTIONAL MATERIALS: Pictures of digestive system, video and animation on the digestive system (https://www.youtube.com/watch?v=Og5xAdC8EUI)
INSTRUCTIONAL PROCEDURES
PERIOD 1: Digestion
PRESENTATION | TEACHER’S ACTIVITY | PUPIL’S ACTIVITY |
STEP 1 INTRODUCTION | The teacher revises the previous lesson on harmful food
| Pupils pay attention |
STEP 2 EXPLANATION | She explains the meaning of digestion Digestion is the process of breaking down food into substances the body can use for energy, tissue growth, and repair The teacher highlights the organs involved in digestion The main organs that make up the digestive system (in order of their function) are the 1. mouth 2. esophagus 3. stomach 4. small intestine 5. large intestine 6. rectum 7. anus. (Helping them along the way are the pancreas, gall bladder and liver). | Pupils pay attention and participates |
STEP 3 DEMONSTRATION | She lists the processes of digestion The processes of digestion include six activities 1. ingestion 2. propulsion 3. mechanical or physical digestion 4. chemical digestion 5. absorption 6. defecation.
The pupils are made to watch a video about how the digestive system works
The teacher further explains the importance of digestion Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body. | Pupils pay attention and participate |
STEP 4 NOTE TAKING | The teacher writes a short note on the board | The pupils copy the note in their books |

PERIOD 2 and 3: Disease preventive measures. Introduction to programming languages
PRESENTATION | TEACHER’S ACTIVITY | PUPIL’S ACTIVITY |
STEP 1 INTRODUCTION | The teacher revisits the previous lesson on ways diseases can be spread | Pupils pay attention |
STEP 2 EXPLANATION | The teacher differentiates between signs and symptoms A symptom is a manifestation of disease apparent to the patient himself, while a sign is a manifestation of disease that the physician perceives. The sign is objective evidence of disease; a symptom, subjective. Symptoms represent the complaints of the patient, and if severe, they drive him to the doctor's office. Signs and symptoms of diseases 1. Fever. 2. Diarrhea. 3. Fatigue. 4. Muscle aches. 5. Coughing The teacher further highlights the preventive measures for diseases 1. Handle & Prepare Food Safely. 2. Wash Hands Often. 3. Clean & Disinfect Commonly Used Surfaces. 4. Cough & Sneeze Into Your Sleeve. 5. Don't Share Personal Items. 6. Get Vaccinated. 7. Avoid Touching Wild Animals. | Pupils pay attention and participates |
STEP 3 DEMONSTRATION | The teacher explains the visual and text based programming languages Visual Basic (VB) Visual Basic (VB) is an event-driven programming language and environment from Microsoft that provides a graphical user interface (GUI) which allows programmers to modify code by simply dragging and dropping objects and defining their behavior and appearance. Text based programming language are languages that are typed using a keyboard and stored as text files | Pupils pay attention and participate |
STEP 4 NOTE TAKING | The teacher writes a short note on the board | The pupils copy the note in their books |
NOTE
Differences between signs and symptoms
A symptom is a manifestation of disease apparent to the patient himself, while a sign is a manifestation of disease that the physician perceives. The sign is objective evidence of disease; a symptom, subjective. Symptoms represent the complaints of the patient, and if severe, they drive him to the doctor's office.
Signs and symptoms of diseases
1. Fever.
2. Diarrhea.
3. Fatigue.
4. Muscle aches.
5. Coughing
Preventive measures for diseases
Visual and text based programming languages
Visual Basic (VB) Visual Basic (VB) is an event-driven programming language and environment from Microsoft that provides a graphical user interface (GUI) which allows programmers to modify code by simply dragging and dropping objects and defining their behavior and appearance.
Text based programming language are languages that are typed using a keyboard and stored as text files
EVALUATION: 1. What is the difference between symptoms and signs?
CLASSWORK: As in evaluation
CONCLUSION: The teacher commends the pupils positively
