Dream big and build tall. Scholars build the tallest tower possible out of plastic or paper cups. They apply the engineering design process to refine their designs and see if they can make their towers even taller.

It seems like skyscrapers are getting taller and taller these days. An interesting video explains the challenges of constructing tall skyscrapers. It uses several examples of existing buildings to show how engineers overcome these...

Concrete, heal thyself! A fascinating video describes the self-healing properties of concrete, known as autonomous healing. Pupils also learn about ways that engineers try to make concrete more resistant to cracks, such as by adding...

Exploding billiard balls and fake tanks are just part of the history of polymers. The 20th installment of the Crash Course Engineering series looks at polymers and how people make them. It also takes viewers through a brief history of...

Don't let materials science break you. An informative video explains the mechanical properties of materials. It uses a stress-strain diagram to discuss elasticity, hardness, toughness, creep strength, and fatigue strength. It also...

Can you see the future in a carbon fiber? A Real Engineering video describes the development of carbon fiber as a building material. It also explains some applications of carbon fiber in aerospace and sporting goods, including proposed...

Steel a great resource to teach your class all about iron. Viewers of an engaging video see how the production of wrought iron, cast iron, and steel have changed over time. The video also explains some societal advances due to these...

There's a reason why they're called I-beams. A short Real Engineering video describes why I-beams are in the shape of an I. It considers how the beam achieves maximum bending load with the least amount of material.

The six words you need to know to describe materials: stiff, strong, ductile, brittle, tough, and hard. Scholars learn how to investigate and describe material properties using a stress-strain graph. They identify yield strength and...

Meet element number 13, aluminum. A video in the Real Engineering playlist explains how people started using aluminum in airplanes, buildings, and power lines. Scholars see how a moment of serendipity led to a process for producing this...

In the video "Keep Out Cows," Curious George tries to build a wall to keep the cows from munching on a flowerbed. He uses newspapers attached to a clothesline, but will they be strong enough to keep Leslie Cow and her friends away?...
