Laboratory Work Execution And Writing from Ralph McMahon's blog

The first step in preparing for laboratory work is to familiarize yourself with theoretical knowledge. To do this, the teacher informs in advance about the upcoming assignment and gives a chance to teach the material, close the gaps in knowledge. If the student, in his opinion, is not sufficiently prepared, the teacher has every right to prevent the practical implementation of the assignment.


Students must understand the theory before doing the lab. In this case, the student will be forced to go for an individual retake, which is usually done with even more difficulty. Otherwise, you can make use of companies to prepare everything. With this type of work, like laboratory work, students should not have indulgences, since unpreparedness, first of all, affects their safety, and only then on knowledge. The algorithm for performing laboratory work, like any other scientific work, has some nuances:

  1. The first thing to do is to carefully familiarize yourself with the equipment with which you have to work. The methodological development and technical documentation will help you with this, according to which you will be able to correctly assemble and determine the required device.
  2. Further, after getting acquainted with the devices, you need to assemble the circuit as indicated again in the development method. You cannot start further actions until your teacher has checked your scheme and is convinced of its correctness.
  3. Before starting to work with the device, you need to set the scale division value, as well as whether there may be errors in the measurement.
  4. A trial run should be carried out to avoid further measurement errors. This way you can be sure of the correctness of your actions.
  5. Now you can start testing and experimenting, having prepared a draft in advance for keeping records, which can be corrected in case of error.
  6. After completing the main work, you need to overtake the rough version of the records in the final one and draw up a competent report on the work done. Do not forget to formulate conclusions in accordance with the requirements of the method of development.


Protection and evaluation of work

Regardless of whether the research was carried out collectively or by each student individually, the defense of laboratory / practical work is strictly individual. This means that you should hire here editors to get a competitive edge. All those who took part in the work should have their own conclusions about the study and a well-written report, which they will subsequently bring to the teacher for verification.


During the defense, the teacher can ask a couple of questions about the theoretical material, thereby checking how you learned the knowledge. He also checks the correctness of the report in accordance with the methodological development. If a student answers the questions posed with confidence, then he / she should not worry about his grade further. But those who could not understand the material will have to sweat or go for a retake, which at the university can take place with a commission. Let's see what and what grade a student can get:

  • "Excellent" is given to the laboratory / practical one, which is completed in full, correctly framed and has well-formulated conclusions. In addition, if a student wants to get an A, he needs to correctly answer all oral questions;
  • “Good” is given for the same well-designed work, but the student gets exactly 4, not 5, because he may incorrectly answer oral questions. Most often this can be due to anxiety before the defense;
  • “Satisfactory” is given for the work that the student could not fully disclose or did only half of it; this can also include the lack of a correct conclusion about the work done or a lot of minor mistakes;
  • "Bad" is received by the student who did not complete the work at all, or the one who did it badly.


We can say that laboratory work is a very exciting process of assimilating theoretical knowledge in practice, but, like other scientific work, laboratory work requires attentiveness, perseverance, diligence and, most importantly, responsibility. If you don't have the time to dedicate to this, then source will be the solution. Because, in addition to the fact that during the research you need to gain knowledge, you also need to behave correctly, since during the experiment, the safety of all participants depends on your actions, in addition to yours. Only under such conditions can you get not only good grades, but also pleasure from work.
