Pascal's law also Pascal's principle or the principle of transmission of fluid-pressure is a principle in fluid mechanics that states that a pressure change occurring anywhere in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.
Speaking of the Pascal Law is certainly about the fluid pressure in the enclosed space. Where if a plastic bag contains water and is perforated in several places with a needle, the water will radiate out. And the jet will be stronger if the top of the plastic is pressed. This indicates that the pressure is forwarded in all directions in water.
In improving students' ability in pascal legal concept. Here I refer to students working in groups to create an example project of pascal law. Students create a learning media about the concept of pascal law in everyday life. In groups students are very enthusiastic in creating different works between groups.
What is needed in making this pascal law of learning media ??
Tools and materials
Needles, plastic hoses, heavy paper, ice cream sticks, used tins, colored water, toothpicks.
How students can created this media
To all groups are given a general picture of pascal law example and how to make it. Where they can give their own ideas in a variety of creativity. So it will produce a good learning media products.
Here are some pictures the media students created.
Conclusion
In accordance with Pascal's legal principle that a pressure applied to a closed fluid will be passed without diminishing to any part of the fluid and the walls containing the fluid. And this concept is of course the same as Pascal's law of sound "The pressure given to the liquid in the enclosed space is extended equally in all directions"
