Fonctionnement - The power of the plants

We put 7 Spanish beans per lid.

3 lids are covered with a stone of different weights as well as small characters.

After two days the character on the lid without stone and the medium stone were tipped over !

After 4 days all the stones were overturned...what a force!

During our experiment, our beans managed to overturn a 400 g stone!!!! Who can do better?!

To calculate precisely the load that the beans managed to lift, you have to add to the weight of the stone that of the character and the lid.

Once the experiment is over, you can plant the beans in the ground or in a pot.
