Zoologists study animals and their behaviour in the wild or in captivity, and how they interact with other species and their environments.

Meteorologists study the physics and dynamics of the atmosphere to increase understanding of weather and climate, and to help them forecast weather patterns and long-term climate trends.

Forensic scientists apply scientific knowledge and skills to investigating crimes and helping the police find or eliminate crime suspects. They may also do research into developing or improving forensic techniques.

Medical physicists help plan radiation treatment for patients, check and monitor radiation equipment, and develop new treatment techniques.

Geologists study the structure and history of the Earth and Earth processes. They also advise on natural hazards and the development and use of the Earth's land and resources.

Science technicians help scientists carry out research, testing and experiments in areas such as chemistry, earth sciences, life sciences, and physical sciences.

Medical laboratory scientists carry out laboratory tests on blood, tissues and other samples taken from patients.

Biotechnologists use their knowledge of living organisms to create new animal or plant-based products such as pest-resistant crops and pharmaceuticals.

Chemists study the make-up and behaviour of chemicals, and may use their findings to develop new products and processes.

Microbiologists study organisms such as bacteria, viruses, algae or fungi, and the effects they have on plants, animals and humans. They also develop products and procedures to benefit humans or the environment.

Marine biologists study animals and plants that live in the sea, and how they interact with their surroundings.

Biochemists study the chemical structure and function of animals, plants and micro-organisms such as bacteria and viruses. They use this research to develop medical, industrial and agricultural products.

Food technologists research, develop and improve food and drink products. They may also be involved in the processing, packaging, storage and safety of food to meet government and industry standards.

Geophysicists use data-collecting technology to study natural processes of the Earth such as earthquake and volcanic activity, and to locate minerals, oil and gas, or ground water.
