In the final part of this Il était une fois... episode on the ecosystems, the Maestro explains what happened to the people and the famous statues of Easter Island. It's a lesson we'd do well to learn from.

The Maestro gives us an overview of some of the major innovations of the last century, from the invention of the radio to the discovery of the first exoplanet. We've come a long way in just a few decades!

In the second part of this Il était une fois... (Once Upon a Time) episode on technology, the kids attend a technology show in Japan, where they play some amazing virtual reality games... and some practical jokes.

The home of the future includes a talking refrigerator that gives you chocolate bars for breakfast! Unfortunately, it also includes some pesky robots....

Technology not only helps clean up our planet, but also allows us to explore the entire universe. According to the astrophysicist Alfred Vidal-Madjar, in five hundred years, we will have visited all the planets in the solar system.

Modern technology comes to the rescue! Planet Earth has a chance of recovering from man-made pollution.

A group of smart young people found revolutionary ways to solve our planet's woes. Electronic books, Internet mail and much more...

The students present the Maestro with various solutions for eliminating pollution on our planet, including vertical farms and biotechnology.

The Maestro explains how the revolutionary ideas of the early discoverers, which we now take for granted, were not always well received. Before Galileo, for example, everyone believed that the sun and all the other planets revolved around the earth!

In this video, a young Galileo gets one of his first revolutionary ideas on how to measure time. Pretty impressive for a fourteen-year-old, huh?

Episode nine of this series focuses on Galileo, a prolific inventor and scientist. He discovered the principle of the simple pendulum motion, very useful in the measure of time and later in the making of clocks.

In part four of this episode on "The Discoverers," Galileo, now a reputable scholar at the University of Padua, proceeds to make a telescope out of lenses with the help of his instrument maker, Marc'Antonio. In this cartoon, an attempt is made to explain Galileo's discoveries.

In part five of this episode on "The Discoverers," Galileo is warned. His belief that the Earth revolves around the sun is sacrilegious. Giordano Bruno, who claimed this fact, was burned as a heretic by the Inquisition Tribunal.

Galileo is about to throw caution to the wind and reveal his startling discoveries about planet Earth.
