LESSON PLAN

DIGITAL TECHNOLOGIES

Subject:	Digital Technologies
Class:	JSS 2
Term:	Third Term
Week:	10
Topic:	Class Project: Building a Simple Robot (Simulation)
Duration:	80 Minutes (Double Period)
Date/Period:	________________________

Learning Objectives

By the end of the lesson, students should be able to:

1. Design and develop a simple digital robot model or simulation.
2. Demonstrate basic robotic concepts through the project.

Previous Knowledge

Students have learnt the parts and functions of a robot, basic robotic movements, programming simple movements and automation. They can use Scratch to program sprites with sequences, loops and conditions and to debug programs.

Instructional Materials

• Computers or laptops.
• Scratch or other robotics simulation software.
• Digital modelling tools, such as the Scratch paint editor.
• Project guide and assessment chart.
• Projector or display screen, where available.
• Whiteboard and markers.

Reference Materials

• Digital Technologies lesson note: Class Project: Building a Simple Robot (Simulation).
• Scratch and robotics simulation resources.
• Teacher-prepared project guide and examples.

Presentation

Stage/Time	Teacher's Activities	Students' Activities
Stage 1 Introduction and Project Brief 10 minutes	Explains the meaning of simulation and digital model. Presents the project, the obstacle-avoiding robot, and shows how the parts of a robot are represented in the simulation. Shares the assessment guide and forms groups.	Listen, ask questions, note the project requirements and join their groups.
Stage 2 Planning and Design 15 minutes	Guides groups to decide what the robot will do, sketch it and label its body, sensor, controller and actuator, and write the steps the robot will follow.	Plan the project, sketch and label the robot and write the steps the robot will follow.
Stage 3 Building and Programming 30 minutes	Guides groups to create the robot sprite and the environment in Scratch, and to program it with a repeat loop, a sensor condition and movement blocks. Moves around the class to assist.	Build the digital robot model and environment, connect the blocks to program the robot and share tasks among group members.
Stage 4 Testing and Debugging 10 minutes	Guides groups to run their programs, find errors and correct them one at a time, then test again.	Run the programs, identify errors, correct them and test again until the robot works.
Stage 5 Presentation and Demonstration 10 minutes	Invites groups to demonstrate their simulations. Asks them to explain how the robotic concepts and automation are shown. Assesses the projects using the guide.	Demonstrate their simulations, explain the robotic concepts in their projects and answer questions.
Stage 6 Evaluation and Conclusion 5 minutes	Asks oral questions, corrects misconceptions and summarises the project. Gives the assignment.	Answer questions, share what they learnt and copy the assignment.

Evaluation

1. What is a simulation?
2. What is a digital robot model?
3. Which part of the Scratch project represents the robot's body?
4. Which blocks act as the sensor and which act as the actuator?
5. What represents the software in the project?
6. How does the project demonstrate automation?
7. What should you do if the robot goes through a wall in the simulation?

Assignment

1. Define simulation and digital robot model.
2. List the five steps for building the simple robot simulation.
3. Explain how the body, sensor, controller, actuator and software are represented in the project.
4. Write the instructions of your obstacle-avoiding robot program in your own words.
5. State two ways in which your project could be improved.

Teacher's Reflection/Remarks

Were students able to design and develop a simple digital robot simulation and demonstrate basic robotic concepts through it? Record any difficulties encountered, such as problems in programming or debugging, and provide additional practice where necessary.
