The AQA A-Level Environmental Science course (7447) 

The AQA A-Level Environmental Science course (7447) offers students a comprehensive understanding of the complexities of the environment and the impacts that human beings have on the natural world. The course allows students to develop scientific skills and knowledge while exploring various environmental topics.

The main areas covered in the course are:

1. **The Living Environment:** This section provides an introduction to the biodiversity of life on Earth, including the characteristics of different environments, such as aquatic and terrestrial, tropical and temperate. It also examines the impact of human activities on the environment.

2. **The Physical Environment:** This section includes study on lithosphere (earth structure, rock cycle, plate tectonics, soils), atmosphere (weather, climate, biogeochemical cycles) and hydrosphere (water resources and pollution).

3. **Energy Resources:** This component focuses on the current energy mix, and explores the advantages and disadvantages of different energy resources, both renewable and non-renewable.

4. **Pollution:** Here, students learn about different types of pollution, their causes, their impacts on the environment and the ways to control them.

5. **Biological Resources:** This section examines different biological resources, their management and conservation.

6. **Sustainability:** This part of the course allows students to explore issues around sustainability, including the sustainable use of water, land and energy resources.

The assessment for this course is typically via two written exams:

1. **Paper 1: The Living Environment and Energy Resources**

   - Written exam: 2 hours

   - Weighting: 50% of A-Level

   - Format: Mixture of short answer, longer answer and extended response questions.

2. **Paper 2: The Physical Environment and Biological Resources**

   - Written exam: 2 hours

   - Weighting: 50% of A-Level

   - Format: Mixture of short answer, longer answer and extended response questions.
