Kit 01Math · Earth and space
Giants
A hundred times bigger over a 1:100 valley: contour-line rescue, a 20,000 m³ reservoir and a 40 m bridge. You have to really measure.

MICRO·MACRO: change size to understand the world
From giants to ants, from cells to galaxies. Doctor Mida guides students through each kit, and the PC program lets you pick them by topic and age. 25 short kits that can be combined in one session.
Illustrative imageHow the collection works
Each kit is a short, complete experience built around one topic. Changing size is the common thread, so students compare scales naturally: how much a crumb weighs for an ant, how many liters fit in a reservoir, how far Jupiter is.
- One kit, or several in a row in the same session
- Difficulty level and short version selectable on the PC
- Up to 10 players in the same world
- Kits of 12 to 20 minutes (short versions of 9 and 11)
Kits 1 to 5 also form a story: the five lenses of Doctor Mida's Scalimeter.

For teachers
Choose kits by topic and age in the PC program, or chain several in one session. Each kit ends with a summary on the PC that you can use back in class.
The kits with their own page (Giants and Ants) include a detailed teacher's guide. For the rest, ask us about the kit that fits your programming.
