YEAR 10 BIOLOGY COURSE SYLLABUS 2020-2021

Course Outline

Overview

Cambridge IGCSE Biology Syllabus at GEMS Wesgreen International Secondary School aims to enables learners to:

increase their understanding of the technological world,  take an informed interest in scientific matters, recognize the usefulness and limitations of scientific method, and how to apply this to other disciplines and in everyday life, develop relevant attitudes, such as a concern for accuracy and precision, objectivity, integrity, enquiry, initiative and inventiveness, develop an interest in, and care for, the environment, better understand the influence and limitations placed on scientific study by society, economy, technology, ethics, the community and the environment and develop an understanding of the scientific skills essential for both further study and everyday life.

Learning Outcomes

The aims of all subjects state what a teacher may expect to teach and what a student may expect to experience and learn. These aims suggest how the student may be changed by the learning experience.

The aims of the Science Syllabus are to encourage and enable students to:

  • Develop scientific knowledge and conceptual understanding through the specific disciplines of biology, chemistry and physics.
  • Develop understanding of nature, processes and methods of science through different type of science enquiries that help them to answer scientific questions about the world around them.
  • Are equipped with the scientific knowledge required to understand the uses and implications of science, today and for the future.

Ongoing Objectives

  • Throughout each unit, the students are given the opportunity to build on the objectives below:
  • provide an enjoyable and worthwhile educational experience for all learners, whether or not they go on to study science beyond this level
  • enable learners to acquire sufficient knowledge and understanding to:
  • become confident citizens in a technological world and develop an informed interest in scientific matters
  • be suitably prepared for studies beyond Cambridge IGCSE
  • allow learners to recognize that science is evidence-based and understand the usefulness, and the limitations, of scientific method
  • develop skills that:
  • are relevant to the study and practice of biology
  • are useful in everyday life
  • encourage a systematic approach to problem-solving
  • encourage efficient and safe practice
  • encourage effective communication through the language of science
  • develop attitudes relevant to biology such as:
  • concern for accuracy and precision
  • objectivity
  • integrity
  • enquiry
  • initiative

Specific National Curriculum Objectives Covered:
• Explain the importance of enzymes and how they function and how denaturation can occur.

4. Biological molecules
This unit will help us to understand: what carbohydrates, lipids and proteins are made of, and their properties, the roles of carbohydrates, lipids and proteins in living organisms, how to test for the presence of carbohydrates, lipids and proteins, the structure of DNA and why water is so important to living organisms.

4.1 Biological molecules
4.1. Chemical composition and monomers
4.1 Using reagents to test
4.1 DNA
4.1 Water as a solvent

5. Enzymes
This unit discusses about enzymes and what they do, how and why enzymes are affected by temperature and pH, and how to investigate the effects of temperature and pH on enzyme activity.

5.1 Enzymes

Classification
• Recall characteristic’s of living organisms.

Movement in and out of cells
• Be able to describe the processes of diffusion, osmosis and active transport
• Explain the factors that affect the rate of diffusion, osmosis and active transport and apply these to examples.
• Describe how transport systems are adapted to ensure that substances can move into and out of cells efficiently.

Biological molecules
• To recall the elements that make up carbohydrates, fats and proteins.
• Describe how to use reagents to test for the presence of biological molecules.
• Explain the role of biological molecules in living organisms.
• Describe the structure of DNA.
• Describe the role of water as a solvent in organisms.

Enzymes
• Describe the function and mode of action of enzymes.

Assessment

Formative: Throughout the units, the children will complete graded work, quizzes and investigation activities, which allows the teacher to assess the students’ attainment and inform their planning.
For each unit the students complete a pre and posttest. This allows us to see progress across the units and to inform our planning.

Summative: At the end of each term, we complete internal tests. This allows us to measure the students’ progress throughout the term and year.
