Part B: Project

Apply force and pressure concepts using simple activities.

Project Title: Force and Pressure in Practice

Objective: Use basic experiments to understand force and pressure.

Project Instructions:

1. Identify two real-life examples of force (push, pull, friction).
2. Perform a simple surface tension or cohesion test (water drops on coin).
3. Calculate weight using W = mg for a chosen object.
4. Explain a pressure example in solids or fluids.
5. Consult your coach where necessary.

Evidence to Submit:

• Notes on examples and observations.
• W = mg calculation.
• Short explanation of pressure example.

Submission

Part C: Training Others

Teach a peer about force or pressure.

Guidance:

• Explain one type of force and one pressure application.
• Demonstrate a simple activity.
• Ask the learner to solve a short problem.

Reflection:

• What did the learner understand well?
• What required extra clarification?
• What support do you need from your coach?

Submission

Part D: Assessment

Competency Levels:

1 = Expectations not met

2 = Partially met

3 = Satisfactorily met

4 = Excellently met

Coach assessment: Learner completes the self-assessment using the 1-4 scale. The coach prepares a short quiz or conversation (outside the system if needed) and assigns the coach score.

Self-assessment:

• Force and types of forces:
• W = mg problems:
• Pressure in solids and fluids:
• Applications of pressure:

Coach assessment:

• Force and types of forces:
• W = mg problems:
• Pressure in solids and fluids:
• Applications of pressure:
