Natural sciences research businesses and organisations investigate the natural world and the processes that shape it. Their work may cover areas such as biology, chemistry, physics, geology, ecology, environmental science and materials science. Researchers use methods including laboratory experiments, field surveys, observation, measurement, modelling and analysis of existing data. Projects may be basic research to build scientific understanding, or applied research aimed at addressing a practical or technical question. Customers and collaborators can include universities, public bodies, charities and businesses in sectors such as healthcare, agriculture, energy and manufacturing. Services may include designing and carrying out research projects, collecting samples or field data, laboratory analysis, statistical and computational modelling, and interpreting findings.
