Water experiment

We took different dishes: bucket, cups etc.

We gathered water from eaves and puddles. We took experiments. At first children guessed which pucket will get full the fastest. Guesses where different. Experiment showed that the narrow bucket will get full the fastest.  

We poured water from the wider bucket to the narrower bucket. It turned out that the water from the other bucket did not fit there. Some of the water remained over. We concluded that one bucket fits more water, otherone fits less. One ise wider, otherone is narrower bucket (the shapes of the buckets are different).  

As we poured water from the mug to the cup it turned out that this cup did not got full. Because into the cup (its bigger) fits more water than it does to the mug (its smaller).

We discuss with children: if you make a hole to the sand and then filled it with water, what happens next? Children guessed, that then the puddle remains. One of them suggested that water goes into the ground. 

The experiment: we made a hole into the sand and filled it with water. We waited and looked, what happens next. Bit by bit the puddle got smaller, lower. So that time would go by faster, we counted the leaves from the birch.

We learned to solve text-task: mari found 5 birch leaves. Mart found 2 birsh leaves. How many leaves do they have together?

 Children were good, some answered correctly immediatly – 7 leaves. At the end we counted the leaves together.

 And surprise surprise our puddle was vanished into the ground. We discussed, why there are puddles outside and why water has not gone into the ground yet: when there is lot of water, then the ground can not absorb the water that quikly.
