Laboratory Techniques and Measurements Lab 1
The purpose of this lab was for the student to get involved with his or hers new lab kit as well as being able to know, identify and use each other tools provided in the kit. Another key learning aspect of this lab is to teach the student how to measure properly the many units in the SI system. I will be using laboratory dilutions, measurements, and weights to then calculate using algebraic formula.
Throughout lab one we were introduced to many different forms of measurement, whether its using a ruler too measure length, a digital scale to measure weight, and also many different sized and shaped flasks to measure different volumes. Another key measurement of this lab was to teach the

My analyses of this lab is like so. The lab presented itself with great learning options for teaching us how to use and proper measure the different units of the Si system, but as easy as they are to learn there are many of possible solutions for error. Since this was the first lab the many of the students have probably done in a couple years, I see plenty of room for human error do to the lack of training or experience with most of the lab equipment required to compete this lab to the full. Not only is there room for human error but there are also the possibilities of error with the lab equipment whether it is the student’s fault or just default equipment. For example, if the digital scale, required for most of the lab, is not tarred right, your numbers from your experiment are going to be way off. One wrong calculation or measurement could ruin a whole exercise if not whole entire lab itself. In my conclusion for this lab was pretty accurate to my hypothesis. I was able to make most of the appropriate measurements with little to no error at all. I had trouble with the density at first seeing I have never used the method for calculating density. After a few tries I was able to succeed in calculating all the appropriate calculation required for this lab as well as using
