Y7J´S SCIENCE

Today in class we did the particle model of evaporation .It is very simple: liquids don´t need fire or very high temperatures .Water can change form to gas in any temperature ,wind helps the evaporation.
Then we did an experiment ,one kid kindly offered himself to do it . It was like this:he poured some water in his head and in some minutes ,it evaporated .
At last ,we learned the words of a scientist that explained what is an atom and said us much more things : "All the things are made of atoms-Little particles that move arround in perpetual motion ,attracting each other when they are a little distance apart and repelling each other when they are sqeezed together".
