Expires on: 

Symmetry plays an important role in determining whether an object is more or less aerodynamic. Our facilitator shows us the symmetry of different structures. Build different types of paper airplane to determine which is more aerodynamic.

E6 : Les sphères - À vous de jouer

2 min 49 s
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.

E13 : Les cubes - À vous de jouer

1 min 49 s
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?
