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

Today, we are going to explore drilling and building techniques underground.

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

What tools do we use to dig and build underground?

To dig under the ground, engineers use special machines like drills and tunnel borers. Drills are big machines that drill through rocks. Tunnel borers are giant machines that dig tunnels by eating the earth and building walls at the same time.

Once the tunnel is dug, it needs to be made stronger. To do this, we use pillars and beams made of metal or concrete. These parts hold up the sides of the tunnel to keep it from falling down. It's like building a house, but underground!

Geologists are scientists who study rocks. They use tools like hammers and magnifying glasses to examine different types of rocks and learn their stories. This helps to know if the rock is strong or fragile, which is important for building.

Knowing the story of rocks is very important. It helps to know if they are stable or if they can move. Geologists help to choose the right materials and techniques to build safely.

To keep workers safe, special steps are taken. For example, they wear helmets and protective clothes. Ventilation systems are installed to keep the air fresh and avoid dangers like poisonous gases.

The Underground Lab

What techniques are used to dig and build underground?

The Discovery of the Lab

After making the ground steady‎ (1) with cement injections‎ (2) and concrete supports, Stephane and Nela, along with their loyal work dog, a shepherd named Max, leave the sinking area. They have saved the homes and understood the causes of the sinking. Now, they are heading to an underground‎ (3) high-tech‎ (4) lab to learn new drilling‎ (5) and building techniques. The tunnel lights guide their way as Max happily trots ahead, his tail wagging with joy.

Soon after, they arrive at the lab. Stephane and Nela are amazed by the fancy‎ (6) machines and tools around them. The walls are covered with bright screens showing complex plans‎ (7) and science data.

Stephane, curious, asks:
« What does this big machine do? »

Nela, curious about the technologies, asks:
« Why are there screens everywhere? »

Stephane, curious about the machines, asks:
« Who can explain to us how all this works? »

An engineer from the lab, happy to share his knowledge, comes over to them. He shows them a big drilling machine. He explains how the machine drills precisely through different layers of rock.

They use special machines and support materials to dig and build underground, while studying the rocks to learn their story.

The Drilling and Building Techniques

Stephane, with his yellow helmet, reflective jacket, and sturdy boots, and Nela, with her blue helmet, long black hair, and backpack full of geology tools, follow the engineer to a big room filled with tunnel models. The engineers explain that the tunnels are built with concrete pillars and reinforcing nets.

Stephane, curious about the explanations, asks:
« Why do you use concrete pillars? »

Nela, curious about the details, then asks:
« What are the reinforcement nets for? »

The engineers show detailed plans. They explain that pillars and nets keep the tunnels stable. This prevents collapses. Stephane and Nela listen carefully.

Nela, curious about the rock samples, asks:
« How did the rocks form? »

Stephane, fascinated by the rock samples, says:
« Each layer tells a different story. »

After listening to the engineers explain the techniques of drilling and underground construction, Stephane, a brave engineer wearing a yellow helmet, a reflective jacket, and sturdy boots, and Nela, an adventurous geologist with long black hair wearing a blue helmet with a headlamp, are led to a tunnel where ancient rocks are displayed. Their eyes shine with curiosity and determination. They will discover how geologists study these rocks to understand the history of our planet. Stephane and Nela are eager to go on an adventure, knowing that every discovery brings them closer to the mysteries of the underground.
