What Chemists and Materials Scientists Do Most chemists and
materials scientists work as part of a team. Chemists and
materials scientists study the structures, compositions,
reactions, and other properties of substances. They use their
knowledge to develop new and improved products, processes, and
materials. Chemists and materials scientists typically do the
following: - Plan and carry out complex research projects, such
as the development of new products, processes, and testing
methods - Direct technicians and other workers in testing
procedures to analyze components and physical properties of
materials - Instruct scientists and technicians on proper
chemical processing and testing procedures, such as ingredients,
mixing times, and operating temperatures - Prepare test
solutions, compounds, and reagents (such as acids) used in
laboratory procedures - Analyze substances to determine their
chemical and physical properties, such as their structure and
composition - Conduct tests on materials and other substanc
