14.1.1 Understanding the requirements for practical endorsement

• Match the practical skill with its description:

  Planning ↔️ Designing an appropriate experiment

  Implementing ↔️ Carrying out the experiment safely

  Analysis ↔️ Processing and interpreting data

  Evaluation ↔️ Assessing the validity of the method
• Order the following experiments by their key learning points:

  1️⃣ Determination of g by free fall: Understand error analysis in timing experiments

  2️⃣ Young modulus determination: Calculate Young modulus using stress-strain curves

  3️⃣ Investigating internal resistance: Measure internal resistance of a power supply

  4️⃣ Standing wave investigation: Observe and measure standing waves

  5️⃣ Charging and discharging capacitors: Understand charging and discharging in RC circuits
• Successful demonstration of practical skills is necessary for students to achieve the practical endorsement in A-Level Physics.
