Lithuanians students working on the topic of Water

The second grade students with teacher Raimonda Zaiciene

The second grade students with teacher performed a flowering bush experiment. The purpose of the experiment was to find out if the water colored with various materials affects the  bushes. The students were divided into three groups and each group received a different bush. In the first jar was simple water, in another water with ink and in another water with  potassium permanganate. The teacher wrote the students' guesses what color will be flowers bloom. After three weeks, the results were discussed. There we saw  flowers bushes with the same colour.

Third-grade students with teacher Lina Stasiuliene
 Third-grade students have been told that water is magical: it can become a cloud, rain, dew-fall, fog, snow, ice and hail. We have been finding out that water is very strong: it can break the toughest rocks, turning them into sand.
Kids were familiarized with water's state during winter, understood important ecological problems, connected to the pollution of water, necesserity of preserving and cleaning of it.
You can travel using the water, it is needed for water-mills, to grind flour, water spins electrical turbines, that provide electricity, because of that we have light, we can listen to a radio, watch TV. Water essential when putting out fires.
Experiment 1: "Water is made out of particles"
Requirements: water, cocktail straw, a paper sheet.Water is made out of particles. It is not a solid object. Kids put drops of water on the paper, and blowwed at it from Start to Finish. While blowing they realized, that water molecules are able to divide and fuse together. Even the tiniest drops can be split into even more tiny drops.
Experiment 2: "The taste of water"
Requirements: a few glasses of water. Five kids go out of the class, while the others decide to say that water in one glass is sweet, while in the other - tasteless. Some kids of our class admitted that they  tasted the sweetness of the water. You can try this out and see if your kids are susceptible to the power of suggestion.
Experiment 3
Requirements: glasses of water, and a glass of dishwasher and capsules of ink.Before the experiment, kids are asked which of these two liquids will dye faster. After pouring the ink in, we see, that water dyes itself faster.

Creating animation in the LOGO team with teacher Alma Maskolaitiene



The fourth grade students with teacher Vilma Indrisiuniene prepared poster about sea fish

Experiments with water in the physics lesson with teacher Alma Maskolaitiene

Students in the 8th grade put irregularly shaped bodies in the water and calculate the volume of the immersed body according to the increased water level. 


8 grade students information collected on special water feature

If you've been climbing in a lake or other water  in the summer, you probably noticed that the water in the bottom is coolder than ever before. Why ? 

An anomaly in the water – what is it?
Most of the materials when are  heated   expands and shrinks when are frozen. However, there are exceptions. For example, water "behave" differently — mini expands (from a certain temperature). This unusual feature is called the anomaly of water.
