What do engineers do?

Engineers are people who use science and maths to design and build new things to solve problems.

Engineers work to make the world a better place. They design bridges, buildings, cars, toys, phones, and even space rockets. Before they build something, they think very carefully and make a plan.

Every engineer is an expert in a different area. Some build buildings, some write computer programs, and some design planes. But they all do the same thing: they find a problem and come up with an idea to solve it.

Engineers are very curious. They keep asking questions like, 'How does this work?' or 'How can I make this better?' Then they try things out, make mistakes, and try again. That is how they find the best answer.

Quick facts

Engineers use science and maths to solve problems.
There are different kinds of engineering, like civil, computer, mechanical, and space engineering.
Before engineers build something, they draw a plan and do sums.
Engineers test their ideas by making small models.
Planes, bridges, and smartphones were all designed by engineers.
If an idea does not work, engineers fix it and try again.

Kinds of Engineering

Civil engineers build bridges and buildings. Computer engineers design software and robots. Space engineers make rockets and satellites.

📐

The Design Process

Engineers first think of an idea, then make a drawing. Next, they build a small model and test it. If it does not work, they fix it and try again.

🔢

Maths and Science

Engineers use maths and science every day. They work out how much weight a bridge can hold. Without these sums, a building would not be safe.

Famous Inventions

Planes, cars, and smartphones were all designed by engineers. Many of the things we use every day started as an engineer's idea. Spacecraft are made by engineers too.
