She presented some experiments:
1- Plasticine in water
2- Syrings with air
3- Syringes with coloured water
4- Fish in the bottle
5- Bottle with two holes
6- Bottle with one hole
7- Syringe with 5 holes
She didn't explain us how the experiments work, she only said us to think about how they could work]]> 2017-02-16 05:45:08 UTC https://padlet.com/alessia_cicca46/Bookmarks/wish/154225190 alessia_cicca46 https://padlet.com/alessia_cicca46/Bookmarks/wish/154267696 On Saturday 11th the teacher presented a PPT about Hidrostatics to our class and then we divided in groups and we answered to some questions:
1- Why snowshoes are much more effective for walking in snow?
2- Why does a sharp knife cut better than a dull knife?
3- Why a karate chop is much more effective than
We answered to the questions and thant the teacher said us to do an experiment where we had to put and press a balloon over a pin.
Here a simulation of the experiment.
The experiment in where we are concentrated i's the firest.

The next time we will discover the winners!]]> 2017-02-17 13:42:20 UTC https://padlet.com/alessia_cicca46/Bookmarks/wish/154576851 alessia_cicca46 https://padlet.com/alessia_cicca46/Bookmarks/wish/155705698 On Saturday 18 th we have studied the Pascal's low or the principle of transmission of fluid-pressure.

This principle says that if a pressure is applied anywhere in a fluid it causes a force, that is transmitted equally in all directions. According to this law if we have a pressure exerted on a fluid in a small clynder, usually by compressor, the force must be exerted over a much large distance. A small force exerted over a large distance is traded for a large force over a small distance. Thought the pressure is the same, it is exerted over a much large area, giving a multiplication of the force.
We also have studied the Stevin's law. The parameters of this principle are the atmospheric pressure (Patm), the density  (d), and the high of the container. The formula is     P= Patm + d × g × h (g is a constant). When h changes its value, change the numeric value of the pressure.

For example we have seen how the principle of the pressure works in the first three experiments and how the force (F) and the area (A) changes with it.
We have also check the answers about Stevin's law and seen how the pressure increase with the changing of the hight (h).]]> 2017-02-25 06:56:47 UTC https://padlet.com/alessia_cicca46/Bookmarks/wish/156169970
