S1 - E7 | Beneath the Earth's Surface

How is the Earth made and why is it important to know it well before building on it?

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

Today, we are going on a Journey to Discover the Earth.

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

The Earth is like a big cake with many layers. It is made of rocks, sand, and clay. These layers are very important for the stability of buildings.

Knowing these layers is important for building strong buildings. For example, if a house is built on soft sand, it might sink like a sandcastle at high tide.

Geologists are experts who study the ground. They look at the different layers of the Earth to make sure buildings are safe and strong.

Thanks to their work, geologists help build strong buildings and protect nature. They make sure our houses and schools are firmly rooted in the ground.

Under the Earth's Surface

How is the Earth made and why is it important to know about it before building on it?

The Earth's Makeup

Back at the Main Fab-Lab, Noa and Zoé build a small, water-resistant bridge by testing different materials. They learned that even animals like ants use the right materials to build their bridges. After experimenting with wood, metal, and plastic, they feel ready for a new challenge. Teacher Astucio then invites them to explore a fascinating(1) topic: the composition of the Earth. They are told that understanding what is beneath our feet is essential for building strong buildings and avoiding disasters.

Teacher Astucio shows them a big model of the ground. Noa and Zoé carefully look at the different layers of the Earth. They see the solid rocks deep down, the sand, and the clay closer to the surface. They find out that these layers affect the stability(2) of buildings.

Noa, curious about the model, asks:
« Why are the layers important? »

Zoé, curious, asks:
« Do the layers of the Earth affect how stable buildings are? But how does it work exactly? »

To understand better, they decide to simulate a landslide(3). They place rocks and sand in a clear box and gently tilt everything. They watch how the materials move and note the weak spots.

Noa, while watching the simulation carefully, says:
« Look, the sand is sliding fast. »

Zoé, after looking carefully, says:
« And the rocks stay in place. That's interesting. »

During the experiment, Zoé notices a small strange shape in a block of dirt. Curious, they decide to take a closer look. In a block of dirt, they discover a tiny fossil... a trace of the past that might hide a forgotten plan!

Unexpected Discovery

Once Noa and Zoé cleaned the block of dirt, they realized it was a tiny sculpted fossil. They were amazed by this discovery.

Noa, amazed, says:
« It's a fossil. It's very pretty. »

After looking carefully at the mini-fossil, Zoé says:
« Yes, it looks like a map. »

Teacher Astucio tells them that fossils are traces from the past. They can show us important information about old rocks(4) and how life used to be. Then they wonder if this fossil might hide a forgotten plan.

Noa, with shining eyes behind his glasses, says:
« We need to study it more closely. »

Zoé, with a clever smile, suggests:
« Yes, let's use a magnifying glass to look at the smallest details. »

After discovering the mystery of the mini-fossil, Noa and Zoé realize they need to use their math skills to solve this puzzle. With their ruler, compass, and calculations, they start to build a complex geometric structure(5). Teacher Astucio explains that math is essential for creating more precise projects and avoiding mistakes. They feel proud of their discovery and eager to share their knowledge with their friends. They now know that the Earth is much more complex than it seems and that every layer is important. Their adventure is just beginning, and they are ready to discover new mysteries beneath the Earth's surface.
