On the road to knowledge with music for 3 to 6 year olds!

Today, we are going to explore bridges.

Pictures of our little adventurers in action - can you come and play with them?

🎼 Ready to move, sing and dream?

This first melody will take you on a musical discovery of the world!

🎤 Move, sing, discover!

Let's get adventurous with this second soundtrack. 😀

🎙 Read the lyrics to our music:

The lyrics of the two songs are identical, only the melodies are different.

The adventure begins with a story and discoveries for 6 - 8 year olds!

📝 Quick summary of key information

How can bridges hold so much weight without falling down?

Bridges are amazing structures that let cars, trucks, and even trains cross rivers, valleys, or roads. But how do they hold so much weight without falling down? Bridges are built with very strong materials like concrete, steel, and wood. These materials are chosen because they are very tough.

Bridges share the weight evenly so they don't fall down. For example, arches help to hold the weight by spreading it out evenly. Imagine an arch like a big smile that holds up everything that goes over it!

Beams make the bridge stronger. They are like the bones of the bridge, giving it strength and stability. Without them, the bridge would be like a house of cards, ready to fall with the slightest breeze.

Engineers use math and tests to make sure bridges are strong and safe. They check every detail so you can cross safely, whether you're walking, driving, or even riding a bike!

The Miraculous Bridge

How can bridges hold so much weight without falling down?

The Discovery of the Miraculous Bridge

After studying the drawings of birds, eagles, and swallows and understanding how air currents support their wings, another wonder in the workshop catches their attention: a clever‎ (1) bridge designed by Leonardo da Vinci. This bridge, with its elegant‎ (2) arches‎ (3) and strong beams, seems to defy gravity. Curious, the two children decide to find out how this bridge can hold so much weight without falling apart.

Lea, curious, says:
« Max, look at this bridge. It is very big and very strong. It does not fall. »

Max, after looking at the bridge more closely, says:
« The bridge has arches and beams. Maybe that's what makes it strong. »

Lea, excited by the discovery, suggests:
« Let's go see the plans. Maybe we'll find some clues. »

Soon after, they find the bridge plans. They look at the details and the measurements. They see that the arches and beams are well placed. They understand that these parts share the weight.

Max, after studying the plans, explains:
« The arches and beams help spread the weight. That's how the bridge stays strong. »

By looking at the plans and testing different materials, they discover the secrets of engineering‎ (4) and building that make this bridge so strong. They start to understand that the principles of physics‎ (5) and engineering are important for building strong and lasting structures. Once Lea and Max understand this, they start drawing their own bridges.

Experimentation and Discovery

After drawing their own bridges, Lea and Max get to work. They start putting together sticks and stones to make arches. They use strings to fix the beams.

Max, while adjusting the wooden sticks, says:
« Lea, the arches are ready. We can add the beams now. »

After fixing the beams, Lea tells Max:
« Max, the beams need to be straight. See, like this, the bridge is stronger. »

Max, after looking at the arches and beams, explains:
« That's right. The arches and beams work together. It's like a team. »

Lea, after checking every detail, says:
« Max, we need to test our bridge. Put some small stones on it. »

Max, after checking, says:
« Okay. The stones hold well. The bridge is strong. »

After testing how strong their bridge is, Lea and Max are invited to explore another wonder in the workshop: the Room of Automata‎ (6). Curious about the mechanisms‎ (7) they just discovered, they can't wait to see how Leonardo's automata work. There, the automata come to life like magic, showing how the inner workings make the robots move and do tasks. The children are excited to find out how these machines work and to understand the principles of mechanics that bring them to life.
