Intent

Through the overarching theme of the nature of science, the course aims to enable students to:

  1. develop conceptual understanding that allows connections to be made between different areas of the subject, and to other DP sciences subjects
  2. acquire and apply a body of knowledge, methods, tools and techniques that characterise science
  3. develop the ability to analyse, evaluate and synthesise scientific information and claims
  4. develop the ability to approach unfamiliar situations with creativity and resilience
  5. design and model solutions to local and global problems in a scientific context
  6. develop an appreciation of the possibilities and limitations of science
  7. develop technology skills in a scientific context
  8. develop the ability to communicate and collaborate effectively
  9. develop awareness of the ethical, environmental, economic, cultural and social impact of science

Implementation

The chemistry course promotes concept-based teaching and learning to foster critical thinking. The chemistry course is built on:

  • approaches to learning
  • nature of science
  • skills in the study of chemistry.

These three pillars support a broad and balanced experimental programme. As students progress through the course, they become familiar with traditional experimentation techniques, as well as the application of technology. These opportunities help them to develop their investigative skills and evaluate the impact of error and uncertainty in scientific inquiry. The scientific investigation then places a specific emphasis on inquiry-based skills and the formal communication of scientific knowledge. Finally, the collaborative sciences project extends the development of scientific communication in a collaborative and interdisciplinary context, allowing students to work together beyond the confines of chemistry.

Impact

Through studying DP chemistry, students will become aware of how scientists work and communicate with each other and of the ethical debates and limitations of creative scientific endeavour.

Chemistry is often called the central science as chemical principles underpin both the physical environment in which we live and all biological systems. It is therefore often a prerequisite for many other courses in higher education, such as medicine, environmental science and engineering.
