Environmental: Environmental engineering’s use science, technology, and engineering principles to clean environment, minimizing the pollution and preventing it from being generated. Environmental engineers work in a number of areas like air pollution, waste disposal, recycling, global warming, water pollution, and other environmental issues. Mechanical: The specialist and managers will work with and learn about simple machines, mechanical design, physics concepts, kinetic energy, mechanical energy, pneumatics and more. Working in teams, designing, building, and testing their own machines and devices will help the children in discovering and having fun while they using STEM.
