Registration of laboratory works in chemistry 

Template for the correct design in study books of laboratory work in natural science academic disciplines

Laboratory work is done according to a specific plan. It, as a rule, simulates in a simplified form the studies that were carried out by the real major scientists of previous years in this field. You must adhere to a standard plan in the design of your laboratory work. In fact, this is an imitation of a protocol of scientific experience or an imitation of a scientific report on a conducted research, and this teaches students to correctly formulate their future research.

The standard description of laboratory work is as follows:

A laboratory lesson is the main type of training session aimed at experimental confirmation of theoretical positions. In the course of a laboratory lesson, students perform one or more laboratory work (tasks) under the guidance of a teacher in accordance with the studied content of the educational material.

Laboratory work is aimed at:

- generalization, systematization, deepening of theoretical knowledge on specific topics of the academic discipline;

- the formation of skills to apply the acquired knowledge in practice;

- development of analytical, design, constructive skills;

- development of independence, responsibility and creative initiative.

For many students, the analysis of work in chemistry is very difficult. However, you can always ask for essay help to explain in detail how to properly analyze information in laboratory work.

The leading didactic goal of laboratory studies is the experimental confirmation and verification of significant theoretical provisions , therefore, they are of primary importance in the study of the disciplines of mathematical and general natural science, general professional and special cycles .

The main goals of laboratory exercises are:

- establishment and confirmation of patterns;

- verification of formulas, calculation methods;

- establishment of properties, their qualitative and quantitative characteristics;

- familiarization with the methods of conducting experiments;

- monitoring the development of phenomena, processes, etc.

In the course of laboratory classes, students develop practical skills and abilities in handling various devices, installations, laboratory equipment, as well as research skills (observe, compare, analyze, establish dependencies, draw conclusions and generalizations, independently conduct research, draw up results).

For laboratory work of a reproductive nature, the guidelines contain:

- the topic of the lesson;

- the purpose of the lesson;

- used equipment, apparatus, materials and their characteristics;

- basic theoretical provisions;

- the procedure for performing a specific work;

- sample report design (tables for filling; conclusions (without wording));

- Control questions;

- educational and special literature.

For laboratory work of a partial search nature, the methodological instructions contain:

- the topic of the lesson;

- the purpose of the lesson;

- basic theoretical provisions.

The form of organization of students for conducting a laboratory lesson - frontal, group and individual - is determined by the teacher, based on the topic, purpose, order of work:

- in the frontal form of organizing classes, all students perform the same work.

- in the group form of organizing classes, the same work is performed by teams of 2-5 people.

- with an individual form of organization of classes, everyone performs an individual task.

Well , we hope you now know how and why to arrange laboratory work. You can always find out more on the https://essayassistant.org/chemistry-help/ if you are still unclear about something.

Also, below we attach a template for the design of the laboratory work (it is worth noting that in some educational institutions they may differ.

Registration of laboratory work (or practical training)

Date : _____ (Answers the question: "When do?" The date - this is one of the important points for the Protocol of any scientific study, because it confirms the reality of carried out work, tie it to a particular time can say that date. - it is necessary element to denote the scientific nature and reality of the research being conducted.)

Laboratory work [or: Practical lesson] No. ___.

Topic: "____ _______________________________________" (Answers the question: "For what reason did you do it?")

Purpose: _ ____________________________________________ (Answers the question: “Why did you do it?” It is important to remember that it is the purpose of the work that aims at the conclusions that you must draw at the end of this work. The goal should correspond to the conclusions, and the conclusions - to the goal.)

Equipment: _ ____________________________________ (Answers the question: "What is needed to complete the work?", And also "What did you learn to use during the work?")

Progress of work: _ ______________________________________ (Answers the question: "What did you do?" In essence, this is a brief summary of your actions with objects and equipment progress is defined in the methodological notes in the "Methods of work", "technique".. - is that must do. The "work progress" is what was done in reality. Of course, they usually coincide!)

Results: _______________________________________ (Answering the question: “What did you observe?” Or: “What did you register?” You need to give specific descriptions of your observations or specific results of measurements, expressed in corresponding figures. Or make sketches of preparations or drawings.)

Results presentation options:

1. Description of the phenomenon.

2. Table.

3. Drawing. It is necessary to sign the name of the figure and make designations of its most important details.

Conclusions: __________________________________________ (Answering the question: “what did you understand?” Or “what did you learn?” Answering this question, one should proceed from the purpose of the laboratory work. With this work you had to prove something, so write what exactly you proved Do not hesitate to draw even "bad" or "unfortunate" conclusions. Even professors and academics constantly correct and improve their own conclusions, such is the peculiarity of research work. What can we say about students? Learn to draw scientific conclusions and improve them! And do not confuse the conclusion and the report! The report answers the question "what did you do?" , and not "what did you understand or learn?" So write in the conclusions about what you learned thanks to the work done, and not about what kind of work you spent.)

Verification : Verified: _____________________ _ ( Grade and / or signature of the instructor.)
