Engineering is becoming increasingly relevant in a rapidly developing world, with recent years seeing a sharp increase in demand for engineering skills to create the objects and infrastructure we rely on.

Each day, engineers across the world take the principles of mathematics and science and apply them to solve real-world problems, designing and constructing everything from cars and bridges to new types of chemicals and computer software.

In a professional setting, engineering is separated into five disciplines:

  • Chemical engineering applies chemistry, mathematics, biology, mathematics, and physics to manufacture fuel, medicines, materials and even food products. In recent years, developments in this area have been instrumental in advancing the efficiency of renewable energy sources and increased battery capacity for electric cars.
  • Electrical engineering is one of the newer engineering disciplines and focuses on electronics and electrical equipment. Those working in this specialty create a wide range of products, from small objects like microchips and computer hardware to gigantic power generators and satellites that orbit the earth.
  • Mechanical engineering deals with the creation and development of mechanical systems that involve any type of motion. Using the principles of math and physics, mechanical engineers design and produce many different machines including wind turbines, airplanes, cars, prosthetics, and machining equipment.
  • Industrial engineering is used in a wide range of industries to increase quality and efficiency. Examples include developing more effective and accurate supply chains, and designing practices and strategies that enable safer work environments.
  • Civil engineering focuses on building structures that are used by the public, including roads, airports, and sewer systems. Some of the most famous of these structures include the Golden Gate Bridge, the English Channel Tunnel, the Great Pyramid of Giza, and the International Space Station.

Along with engaging in the other components of STEAM, practicing engineering allows children to tap into their natural curiosity and develop creative ways to overcome challenges they have experienced in their own lives.


Engineering can be broadly described as the application of scientific principles in order to create objects, machines, structures, products, and more. It is most commonly divided into four main fields: civil engineering (buildings, bridges, infrastructure, etc.), electrical engineering (electronic devices, electrical circuits, control systems, etc.), mechanical engineering (robotics, vehicles, engines, etc.), and chemical engineering (chemical manufacturing, oil refinery, etc.) However, aerospace engineering is sometimes included as a distinct fifth branch.

In truth, the importance of teaching engineering concepts and principles within academic institutions cannot be overstated because the world needs engineers of all kinds to create the objects and infrastructure we rely on.

In addition to engineering being dependent on scientific principles, there is a major cross-over with mathematics and especially geometry. However, engineering also links with the other STEAM fields in various ways. The arts, for example, are based on creativity, and there is a very clear artistic element to designing and engineering a bridge or a building. Similarly, the actual engineering process relies on technology, including computers and other machines.
