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...

According to NASA, global sea levels rose 17 cm in the last century and 30 cm in the last decade. The video highlights a scientist who predicted climate change, and who offers solutions to change the course of global warming. 

Why is wood good for building houses, but not the best choice for high-rise apartments? Future materials scientists put building materials to the test using a hands-on interactive. Pupils pull and push on substances such as reinforced...

Every human is unique, from our thoughts and actions to our DNA. Scientists spent billions of dollars and over a decade to map the human genome, the sequence of DNA within one human being. Since the project was completed ten years ago,...

Students explore the response of springs to forces as a way to begin to understand elastic solid behavior. They gain experience in data collection, spring constant calculation, and comparison and interpretation of graphs and material...

The enormity of the solar system can sometimes be too big to imagine. A scale model can help us visualize the size in an easy to understand way. Watch as scientists build a model of the solar system in a dessert just 7 miles in diameter!...
