·When I was a child… My mom used to be been with me. A lot of yogurt and milk used to be eaten by me. My dolls used to be played by me for hours. 

·An example of instrument…Total Station (topography) has been varied and advanced by Topographical instrumentation at par with electronics. The chains and ropes can be remembered, in the year 3000 A. of C. were used by the Babylonians and Egyptians. The angular measurement has given its fruit and result. The applying quadrant was discovered by Ptolemy with astronomical observations. The first sight was manufactured by Adrien Bordalouë for leveling. The first automatic level was made from studies and attempts. The race against time has been even faster and more effective.

·Hypothesis: Used loosely, an observation is explained by a tentative conjecture, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation. 

·Standar: Quality control: mechanism was designed in the laboratory to detect, reduce, and correct possible internal analytical deficiencies, a result is issued before.
