INSTRUCTIONAL PROCEDURES

PERIOD 1-5

PRESENTATION
STEP 1: INTRODUCTION

• The teacher will introduce the topic of rockets and satellites and ask the students what they know about them.
• Students will share their prior knowledge, and the teacher will guide them to understand the connection between rockets, satellites, and modern technology.

STEP 2: EXPLANATION

• The teacher will explain the basic structure and components of rockets and satellites.
• Rockets: Propellant, guidance system, payload, fins, and engines.
• Satellites: Solar panels, communication system, sensors, and propulsion system.

STEP 3: DEMONSTRATION

• The teacher will display a chart showing the component parts of a rocket and a satellite.
• The teacher will show a video explaining how rockets launch satellites into orbit and their subsequent functions.

STEP 4: DISCUSSION

• The teacher will lead a discussion on the various uses of rockets and satellites, such as in communication, GPS, weather forecasting, and space exploration.

STEP 5: NOTE TAKING

• The teacher will provide a summary note for the students to copy.

NOTE:

• Components of a Rocket:

1. Propellant: Fuel used to propel the rocket into space.
2. Guidance System: Ensures the rocket follows the correct path.
3. Payload: The object the rocket carries, such as a satellite.
4. Engines and Fins: Help the rocket to launch and stabilize during flight.

• Components of a Satellite:

1. Solar Panels: Convert sunlight into electrical energy.
2. Communication System: Transmits signals to and from Earth.
3. Sensors and Propulsion System: Helps the satellite perform its functions in space.

EVALUATION

1. What are the main components of a rocket and a satellite?
2. Explain the role of the guidance system in a rocket.
3. List three uses of satellites.

CLASSWORK:

• Draw and label the component parts of a rocket.
• List five functions of satellites.

CONCLUSION:

• The teacher will review the students' answers and provide feedback.

Students will reflect on the importance of rockets and satellites in space exploration and communication.
