However, before you can use these shades, you need to understand how they are made. You realise that the shades of white and blue would be perfect for a piece of art you are currently working on. On a table were the Blueprints for the building. While on a school trip, you saw that some renovation work was being carried out by some builders. Investigating the process of producing Blueprints and the role UV light plays.Producing an image or diagram on my Blueprint paper.Carrying out an experiment to produce Blueprint paper.The iron(II) ion reacts with the potassium ferricyanide to form an insoluble blue compound, blue iron(III) ferrocyanide, also known as Prussian blue. The two iron salts do not react with each other in the dark, but when they are exposed to ultraviolet light the iron(III) ammonium citrate becomes an iron(II) salt. The paper is coated with a solution of two soluble iron(III) salts.

Thanks you. You can use it to play the dot game with dots, this works when the grid lines are very light, that allows you to use a pen or pencil to darken them, also it helps if the grids are large. You can use it to create crossword puzzles. You can fill in blocks in black or color to create graph art. Also a block can help children separate words which is helpful since children often have problems with spacing.
Letters that dip under the line like the lowercase "p", "g", and "y" can take up the bottom two rows. Lowercase letters should take up only the second row. Capital letters can take up the top two rows. For example you can use a three block row. It can also be used as a writing aid, specially for children learning to write. Graph papers keep those number neat and aligned. Having multiple numbers in a small space can make it confusing to determine which numbers should be added, subtracted, multiplied, etc. You can also use it to do multi digit math. Instead of placing the ruler on the object you can place the object on the paper. You can use graph paper as a two dimensional ruler.
For example to plot and study lines, functions, and data. This makes graph paper ideal for taking notes on math related subjects. Graph paper is available in many different measurements, for example each box can be centimeter or an inch in length.įor example anything using the cartesian system can make use of graph paper since the cartesian system is essentially a grid. Graph paper is useful when you want to draw things to some kind of scale, instead of measuring each line with a ruler as you draw it you let the graph paper serve as a guide. It is made of up fine lines arranged vertically and horizontally as to create many small boxes. Graph paper is paper meant to be written and drawn on.
