Summary

• Description:

  The MS Word document comprises the Grade 7 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): Separation of a Mixture
    • Objective: To separate a mixture containing sand, iron filings, and maize grains (or beans) into its individual components.
    • Materials Provided: A mixture of sand, iron filings, and maize grains (or beans); a magnet; a sieve; and two empty containers.
    • Procedure Involves:
      • Identifying and listing the three components present in the mixture.
      • Describing a step-by-step procedure to separate the components, explaining the method used at each step. This will involve:
        • Using magnetic separation to remove the iron filings.
        • Using sieving to separate the sand from the maize grains (or beans).
    • Analysis and Reporting Requirements:
      • Naming the three pure components obtained after separation.
      • Listing three laboratory apparatus necessary for the practical (other than the empty containers).
      • Stating one safety precaution observed during the practical.
  • Question 2 (10 marks): Measuring Volume
    • Objective: To measure a specific volume of water using a measuring cylinder and to determine the volume of a rectangular wooden block.
    • Materials Provided: A measuring cylinder, water, a rectangular wooden block, and a ruler.
    • Procedure Involves:
      • Measuring and pouring a specific volume of water (exactly 60 cm³) into the measuring cylinder and reading the volume (confirming the meniscus reading).
      • Identifying the unit of volume indicated on the measuring cylinder.
      • Using a ruler to measure the length, width, and height of the rectangular wooden block.
      • Calculating the volume of the wooden block using the formula: Volume = Length × Width × Height.
    • Analysis and Reporting Requirements:
      • Recording the measured volume of water.
      • Recording the measured dimensions (length, width, height) of the wooden block.
      • Showing the working for the calculation of the wooden block's volume.
      • Naming two laboratory instruments necessary for this practical.
      • Stating one safety precaution to be taken when handling the measuring cylinder and water.
