Children have three glasses of water. In N.1 glass of cold water, they add a sugar cube. In a minute disappears (dissolved) sugar cube. In the second glass N.2 with hot water dissolves the sugar cube in half the time against the glass N.1. Dissolution time depends on the temperature of the water.
The kids have two glasses: one with pure water and the other with milk. In the two glasses lays out various objects (eg pebbles). In the glass with the clean water, they see the stone, but in the glass of milk is not visible stone. Why is that?
On the inside edge of a bowl of clean water puts kids toothpicks. Then place the a sugar cube in the middle of the bowl. What happens with toothpicks? Toothpicks change position to the sugar cube sucking in ambient water, and there arises a suction force (power output) that moves the toothpicks to the middle of the bowl.
For the untrained mind of a child is water tasteless. There is more than enough at this stage of knowledge. There are other teachers in a natural succession, which explains in more detail about the water's true nature. Delete

My name is Elena S. Asberg and works as a preschool teacher in Västerås.Jag bisphenol a has also worked as a primary school bisphenol a teacher and director of studies. In 2009, I received Västerås Educational price for my work with mathematics in kindergarten. In 2010, I let publish my book on mathematics in kindergarten: "Family Tale Geometry". I do not just focus on the purely mathematical, but adds other aspects in dealing with kids: empathy, universal equality, gender perspectives and environmental bisphenol a issues. In my blog called Lena matt cottage you can find a variety of teaching materials bisphenol a that I developed myself. It is my fervent hope that you may find useful material here, and I are grateful for all the comments on my blog!

Thanks in advance and extremely welcome to my blog!
My interests are nature and the environment in which I find even a thousand examples of mathematical relationships. Walking and tranquility of the woods gives me harmony. Otherwise, bisphenol a my hobbies music, family and friends. View my complete profile
