This report provides a comprehensive overview of the Cambridge Lower Secondary Science (0893) syllabus and its assessment through past papers. Overview of Syllabus 0893

Cambridge Lower Secondary Science (0893) is a framework for students aged 11–14 (Stages 7–9). It was introduced for first teaching in September 2021 and first examined via Checkpoint in 2023. The curriculum is structured into six "strands" across three categories: Focus Areas Content Biology, Chemistry, Physics, Earth and Space Key scientific concepts and facts. Skills Thinking and Working Scientifically Developing scientific models, enquiry, and practical work. Context Science in Context Connecting science to the real world and sustainability. Exam Format and Structure

The Cambridge Lower Secondary Checkpoint Science (0893) exam typically consists of two papers, each designed to monitor progress rather than serve as a final qualifying degree. Paper 1 & 2: Each paper is approximately 45 minutes long. Total Marks: 50 marks per paper.

Weighting: Content is roughly distributed as 20% each for Biology, Chemistry, and Physics; 15% for Earth and Space; and 25% for Scientific Thinking.

Question Types: Includes labeling diagrams, density calculations, explaining concepts (e.g., photosynthesis, tectonic plates), and plotting experimental results. Scoring and Performance

Section A: Biology

Question 1: Cells and Organisms (a) Figure 1 shows a diagram of a typical animal cell. (Insert diagram of a cell with nucleus, cell membrane, cytoplasm)

(i) Label parts A and B on the diagram. [2]

  • A: ________________________
  • B: ________________________

(ii) Which part of the cell controls the cell’s activities? [1]

(iii) State one difference between an animal cell and a plant cell. [1]

Question 2: Ecosystems A student investigates the population of woodlice in a garden. They use the capture-recapture method.

  • 40 woodlice are caught, marked, and released.
  • One week later, 50 woodlice are caught.
  • 10 of these woodlice are marked.

(i) Calculate the estimated population size of the woodlice using the formula: $$Population = \frac\textNumber in 1st catch \times \textNumber in 2nd catch\textNumber marked in 2nd catch$$ [2]

  • Calculation: ____________________
  • Population: ____________________

(ii) Suggest one reason why the population estimate might be lower than the actual population. [1]

Why Focus on the 0899 vs. 0893 Transition?

It is important to note that Cambridge recently transitioned from the old code (0893) to a new code (0899) for Lower Secondary Science. However, the content, skills, and question styles have remained largely consistent. When searching for "0893 past papers," you are effectively looking for the foundational set of exams that define the current style of testing scientific enquiry, biology, chemistry, and physics at this level.

4. Scientific Enquiry (Working Scientifically)

This strand is unique to Cambridge. It tests how you set up experiments, identify variables (independent, dependent, controlled), and critique methods.

Past paper clue: "Evaluate this experiment" or "Suggest one improvement"—these require you to spot errors in reliability or accuracy.

What is 0893 Science?

Before diving into the papers, it is essential to understand what the code "0893" represents. In 2021, Cambridge Assessment International Education updated its Lower Secondary Science curriculum from the old code (0893 is the current standard, replacing the older 1113 entry code in some administrative contexts, though 0893 remains the primary teaching framework identifier).

The 0893 curriculum aims to develop:

  • Scientific thinking (hypothesizing, experimenting, concluding).
  • Collaborative skills (working in groups to solve problems).
  • The ability to apply knowledge to real-world contexts.

Students typically sit for the Cambridge Checkpoint test at the end of Stage 9. 0893 Science Past Papers are the official previous exam papers that provide an exact blueprint of what to expect.

Sample Question (to illustrate style)

A student investigates how temperature affects the rate of reaction between hydrochloric acid and magnesium.
a) Name the independent variable. [1]
b) Suggest one variable they should keep constant. [1]
c) Describe how they could measure the rate of reaction. [2]

(Mark scheme gives credit for "temperature", "volume/conc. of acid", and "time to see effervescence stop / collect gas volume per minute".)
