What do engineers do? Mechanical engineers design machines that move -- cars, airplanes, roller skates and other spacecraft like rocket ships. Electrical engineers design things that run on electricity like television sets, digital watches, microwave ovens, I-pods, computers... Civil engineers design solid structures like roads, bridges, tunnels, and stadiums. Chemical engineers design processes that involve chemical reactions like making gasoline or cake mix.
