Cartographie - À vous de jouer

In this capsule, we do the experiment to confirm that the volume of a cone is three times smaller than that of the cylinder that contains it.

Find two cylinders of the same capacity with bases of different diameter. Make their pattern and compare their surface. Have fun.

The facilitator demonstrates that the volume of a square-based pyramid is three times smaller than that of the cube that contains it. Next, she demonstrates how to use chenille stems to form a pyramid and make it a pretty decoration.

In this capsule, we compare solids according to their surface area and their volume. Then, do an experiment by preparing a liquid mixture to make bubbles and see if you can produce spherical bubbles.

Lattices are the structures formed from different triangles. Our facilitator presents the equilateral and isosceles triangle and shares the particular properties of the triangle by explaining to us how to calculate the area.

Our facilitator shows us how to create the Fibonacci spiral using squares. Afterwards, experiment by reproducing this same spiral or a helix.

What is the difference between convex lens and concave lens? Our host demonstrates how a lens changes the path of light, or a laser, in this case. It's up to you to create your own lens.

Symmetry plays an important role in determining whether an object is more or less aerodynamic. Our facilitator shows us the symmetry of different structures.

Come discover the shapes that make up a dome and then make one from newspaper.

Find out what "Plato's solid" means and the five solids that exemplify it.

The cube has special properties. For example, all of its faces are congruent. There are eleven patterns to represent the development of the cube. The facilitator gives two examples. Can you find the other nine patterns?

If we add the number of faces to the number of apex and subtract the number of edges of a prism, we always get the number two. Our facilitator demonstrates this.

There are two types of symmetry: axial symmetry and rotational symmetry. It's your turn to experiment with sliding reflection.
