Summary

• Description:

  The MS Word document comprises the Grade 9 Integrated Science Paper 2 (Practical) Mid Term 2 Exam 2025 with Marking Scheme. The PDF version is also available upon your request.

  The exam paper, titled "INTEGRATED SCIENCE (Practical) PAPER 2," consists of 2 practical questions. The total time allocated for the paper is 1 hour 30 minutes. The exam is marked out of a total of 30 marks.

  The practical tasks and concepts covered in this exam are:

  • Question 1 (20 marks): Investigation of Metal Reactivity
    • Objective: To investigate the reaction of three different metals (labelled Metal P, Metal Q, and Metal R) with dilute hydrochloric acid.
    • Procedure involves:
      • Adding dilute hydrochloric acid to separate test tubes.
      • Introducing each metal sample to the acid.
      • Observing and recording reactions (e.g., bubbling, change in metal appearance, temperature change).
      • Performing a test to identify any gas produced (specifically hydrogen).
    • Analysis and Reporting:
      • Recording observations in a table.
      • Arranging the metals in order of decreasing reactivity based on observations.
      • Stating the test for hydrogen gas and its expected positive result.
      • Writing a general word equation for the reaction between a reactive metal and hydrochloric acid.
      • Naming essential laboratory apparatus for the experiment.
      • Stating safety precautions to be taken.
  • Question 2 (10 marks): Investigation of Spring Extension (Hooke's Law)
    • Objective: To investigate the relationship between the extension of a spring and the load applied to it.
    • Apparatus provided: Spring, metre rule, stand and clamp, and a set of known masses or mass hangers.
    • Procedure involves:
      • Setting up the apparatus with the spring suspended vertically and a metre rule alongside.
      • Measuring and recording the initial length of the spring (with no load).
      • Adding masses incrementally to the spring.
      • Measuring and recording the new length of the spring after each mass is added and the spring is at rest.
      • Calculating the extension for each load (New length - Initial length).
    • Analysis and Reporting:
      • Recording load, length of spring, and extension data in a table for at least four different loads.
      • Describing the observed relationship between the load and the extension.
      • Stating the SI unit for length.
      • Identifying the physical quantity represented by the 'Load' (Force/Weight).
