Laboratory work on chemistry is a small scientific experiment and the report on the conducted experiment. Certain requirements which cornerstone the detailed description of the conducted research is are imposed to its registration.
Instruction
1. At school, laboratory works on chemistry are generally carried out in process (or after) new swore at explanations. Therefore results of experiments are usually described in a workbook. But if this summarizing task under the studied section or a subject, then is carried out it by pupils independently, and the report is brought in a special notebook for a practical training. Though requirements to registration of laboratory works are imposed identical.
2. Recede from the previous work three-four cages down and write down date of performance of laboratory work. Provide its number below. And further, in each new line, write a subject, designate to the purpose of practical work, a perechistita the used equipments and reactants. In the following line enter the heading "Work Course" after which give the stage-by-stage description of the made experiment.
3. The report on laboratory work is recommended to be done laconic. Though in a form it can be any - at your choice. Surely provide the observations of it in the description of experience. Write the equations of chemical reactions confirming the course of an experiment and also a formula, the name of all reagents and products of reaction. Do not forget to specify conditions under which these reactions happen.
4. In laboratory works on chemistry often it is required to fill out the table, to make the drawing of the equipment or the scheme of the made experiment.
5. Draw the table in all width of a writing-book leaf. Then accurately and accurately fill out all necessary columns.
6. Carry out drawings and schemes a simple pencil on the left side of the writing-book page, and to them do signatures strictly below.
7. If you do the drawing of model of the device, then designate on it all components of the equipment. Number them, and issue names in the form of footnotes under the image.
8. At the end of laboratory work formulate and write down a conclusion which is drawn proceeding from the objects set to a practical task.
