Introduction

  • Purpose: To support students in preparing for the Cambridge IGCSE Combined Science or Co-ordinated Sciences courses.

  • Structure: Divided into Biology, Chemistry, and Physics sections.

Core and Supplement

  • Course options:

    • Cambridge IGCSE Combined Science (0653): Single award.

    • Cambridge IGCSE Co-ordinated Sciences (0654): Double award.

  • Overview of examination structure, including Practical Test (Paper 5) and Alternative to Practical (Paper 6).

Study Structure

  • Each chapter includes key terms, short answer questions, longer questions, and practical activities to develop skills.

  • End-of-chapter summaries are provided, alongside revision resources available on a CD-ROM.

Key Terms and Concepts

Movement in and out of Cells

  • Diffusion: The net movement of molecules from an area of higher concentration to an area of lower concentration.

  • Osmosis: A specific type of diffusion involving the movement of water across a semi-permeable membrane.

Photosynthesis

  • Equation: 6CO<em>2+6H</em>2Oext(sunlight,chlorophyll)<br>ightarrowC<em>6H</em>12O<em>6+6O</em>26CO<em>2 + 6H</em>2O ext{(sunlight, chlorophyll)} <br>ightarrow C<em>6H</em>{12}O<em>6 + 6O</em>2

  • Factors requiring investigation: roles of chlorophyll, light intensity, carbon dioxide, and the impact of each on the rate of photosynthesis.

Chemical Reactions

  • Redox Reactions: Reactions involving the transfer of electrons, summarized with equations such as extFe<em>2O</em>3+3extCO<br>ightarrow2extFe+3extCO2ext{Fe}<em>2O</em>3 + 3 ext{CO} <br>ightarrow 2 ext{Fe} + 3 ext{CO}_2.

  • Acid/Base Reactions: Provided examples of chemical equations related to neutralization and the outcomes of these reactions.

Sound Waves

  • Propagation: Sound travels as a mechanical wave through air, liquids, and solids, with a speed of approximately 330 m/s in air.

  • Factors influencing sound: various materials affect the speed of sound, as shown in table:

    • Speed of sound in different media: air (330 m/s), water (1500 m/s), iron (5100 m/s).

Practical Investigations

  • Details on experimental techniques and activities such as measuring the speed of sound, testing for starch in plants, and methods to assess the rusting of iron.

  • Emphasis on safe laboratory practices and the methodological design of experiments.

End of Chapter Questions

  • Each chapter concludes with a series of questions designed to assess understanding and reinforce key concepts, along with examples of past examination questions.

Summary of Key Chemistry Concepts

  • Distinction between industrial processes such as the extraction of metals (iron, aluminium) and their chemical principles (e.g., the Haber process, formation of fertilisers).

  • Importance of recycling and environmental implications of chemical waste and resource management.

Additional Resources

  • CD-ROM includes revision checklists, multiple-choice questions, self-assessment, and answers to end-of-chapter questions.
