Summary

• Description:

  The MS Word document comprises the Grade 7 Integrated Science Paper 1 (Theory) Mid Term 2 Exam 2025 with Marking Scheme. The PDF version is also available upon your request.

  The exam paper, titled "INTEGRATED SCIENCE (Theory) PAPER 1," is divided into two sections, A and B. The total time allocated for the paper is 1 hour 40 minutes. The exam is marked out of a total of 70 marks.

  The structure and content of the exam are as follows:

  • SECTION A (30 marks)
    • This section consists of 30 multiple-choice questions, each worth 1 mark.
    • Topics covered include:
      • Introduction to Science: Basic science skills (e.g., measuring), branches of Integrated Science (Biology).
      • Laboratory Safety and Apparatus: Identifying hazard symbols (e.g., corrosive), laboratory safety rules (e.g., reporting breakages), items in a First Aid Kit, accurate measurement of liquid volumes (using a measuring cylinder), identification and use of laboratory apparatus (e.g., tripod stand, Bunsen burner operation for a non-luminous flame), parts and use of a microscope (coarse adjustment knob).
      • Living Things: Characteristics of living things (e.g., growth), human digestive system (where digestion starts), human respiratory system (identification of parts like trachea).
      • Measurement: Reading packaging labels for information, basic quantities and SI units (mass - kg/g; length - metre).
      • Properties and Classification of Matter: States of matter (sublimation), types of mixtures (solutions, suspensions), methods of separating mixtures (filtration, evaporation, decantation).
      • Acids, Bases, and Indicators: Identifying laboratory acid-base indicators, natural indicators (purple cabbage), effect of acids/bases on litmus paper, understanding the pH scale, common uses of acids and bases (e.g., neutralizing acidic soil).
      • Careers in Science: Differentiating science-related careers from others.
      • Plant Biology: The process of photosynthesis.
  • SECTION B (40 marks)
    • This section consists of 10 short, structured questions with varying mark allocations.
    • Biology Topics:
      • Classification of animals (identifying invertebrates and examples of different vertebrate classes from images).
      • Microscopy (identifying parts of a microscope from a diagram, calculating total magnification, stating function of parts like the revolving nosepiece).
      • Human Physiology: Products excreted by the kidneys, importance of excretion.
    • Chemistry Topics:
      • Properties of matter (definition of matter, properties of solids).
      • Laboratory procedures (determining the volume of an irregularly shaped object using water displacement).
      • Laboratory equipment (identifying a Bunsen burner, its handling, care, and labeling its parts).
      • Elements and compounds (differences, examples of gaseous elements and liquid compounds, difficulty in separating compounds by physical means).
      • Acids, bases, and indicators (classifying substances using litmus paper, identifying common household acids/bases, interpreting the pH scale and Universal Indicator colors).
      • Separation of mixtures (naming the method of filtration, identifying the type of mixture suitable for filtration, explaining its suitability, and giving practical household examples).
    • Physics Topics:
      • Measurement (identifying apparatus for measuring time and length from images, identifying apparatus for measuring a derived quantity like volume, SI unit for volume).
