How to make a puddle or the shapes of the water

Inspired by the explorations in the “Big Puddle” (forest) we decided to find out how to make puddles (indoors)…

F. used a big ball of clay and dug a whole in it with both hands…


 (E. made a small hole in the clay using a piece of wood, carefully twisting it back and forth in the same spot) 

“Look, look,  I made one! (a puddle) I want to try it with the water” , E.
J. was interested in the tubes, so we integrated them

The children were curious to know where the water would go and tested the construction by pouring water in the ‘canal’ leading to the puddle:

“It’s going everywhere!!!”, E.
(The water was leaking from the  puddle and spreading everywhere in the black tray)

The children helped each other to recover the water with sponges, squeezing it into a bucket and then back to the jug to be reused in the next test. After fixing the problems found in the first test, they tested again, and fixed again and tested again, and fixed again the problematic areas , and so on

After quite a few times of this fixing and re-testing, the leakage problems persisted.

“I have an idea! We can use this (wooden blocks) to make walls , I show you…(C. builds it) like this, see?” C.

The children thought it was a good idea and worked on making walls with the wooden blocks, to see if this technique would stop the water from leaking.

The children testing/observing results of the new construction technique  
…and the works continued: build, testing, destroying, adjusting, check for “holes” and 

With every successful test, the children challenged themselves more to extend the ‘puddle’ that in fact became more like a “water slide”, L.  

“Here, for the water…”, V.
(water that was leaking where both hoses met)

“The water goes from here (points to the highest funnel on the window), then passes here and then it finishes here , but there’s a hole… it’s here, the hole, the water came out from here, we need more clay to fix it”, L. explains
