In beaker A, you can see the oil and the water existing in separate layers. In beaker B, the beaker is shaken up, which disperses the oil in the water temporarily. When you set it back down again, however, (beaker C), you can see that it separates again. In beaker D, we added an emulsifier.
Why PI Was Created. PI was created to provide high school students a place where they can create their invention ideas. Too often, students conceive ideas that can change the world. Due to insufficient support and guidance, most high school students cannot bring their invention ideas to life.
Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter â Ï â) is the symbol used in mathematics to represent a constant â the ratio of the circumference of a circle to its diameter â which is approximately 3.14159. Pi has been calculated to over one trillion digits beyond its decimal point.
