Laboratory manual is Dr. P. Scheiber, Dr. P. Nemes, Dr. T.R. Varga, Dr. Z. Vincze, and Dr. M.V. Pilipecz: Veterinary and Food Chemistry Laboratory Manual. Its use is prescribed; this manual serves as the laboratory protocol, as well. It can be received in the first week of the semester.

The first five labs (Organic chemistry lab 1-7.) are only online, and the recorded experiments can be downloaded from the Intranet (after username/password login) or the Moodle system. Students are asked to complete the relevant parts of the practical (observations, reaction equations) using the downloaded material, and upload the photos of the filled pages to the Moodle system (before Sunday midnight), compressed in the following file format: secondname_firstname_x_group.zip.

From the seventh week (March 22), the labs will continue in the traditional (contact) form (the exact schedule can be found in the Guide). Like the previous semester, the introduction of the given lab (relevant accident prevention guidelines, demonstrations, other information) will be recorded and available to students on Moodle system. Also, only one group (15 students) can work in the laboratory at the same time. If the first group is ready for the manual work (measurements, experiments, etc.) the next group can replace the first and start the work.

In the 7. and 9. weeks (March 22, April 6), in the contact organic chemistry labs students repeat manually some selected experiments. (The experiments will be given later.)

 

In the ninth week (April 12-16) all students are obliged to perform one written test whose subject includes the topics of the organic chemistry laboratory exercises and the related lectures. Depending on the pandemic situation, this can be in written (contact) form during the labs or online (oral or written) form.

The contact laboratory exercises will be 45 minutes/group:

 

7, 8        on          Tuesday,             8:15 – 9:45

5, 6        on          Tuesday,             14:15 – 15:45

11, 12    on          Tuesday,             16:15 – 17:45

3, 4        on          Thursday,           10:15 – 11:45

1, 2        on          Thursday,           12:15 – 13:45

9, 10     on          Friday,                  8:15 – 9:45

 

 

in Student Laboratory (Hallgatói Labor) of Chemistry Department (No. 8 at ground floor in bldg. C). We will check the student’s work in the uploaded file (online labs) and in the contact labs also. Only the one who has not got missed lab can get signature at the end of the semester.

Evaluation description

 

Work in the Laboratory

1) Participation on each contact laboratory practical is compulsory and the attendance will be recorded each time. Students who are unable to take the laboratory exercise(s) are obliged to give a satisfactory oral review of the subject(s) missed during their excused absence (make-up lab).

For the make-up lab one should fill (copy and learn) all the missed lab(s) in the Manual and (s)he will be asked a few short questions from the missed lab (ONLINE). If they are properly answered then one can get the valid signature(s) for the missed lab(s). Note: the exam is not allowed with a missed lab exercise(s).

2) A thorough theoretical preparation is required to a successful laboratory work! Therefore, a precise study of the related section of the laboratory manual and the thematically relevant chapters of the lecture prior each laboratory exercise is a must. The preparedness of students can be checked at any time during the lab course and an unsatisfactory result will be considered as a missed lab exercise.

3) Wearing an apron (lab coat) and safety goggles is compulsory in the laboratory. At the first exercise every student has to choose a permanent place at one of the lab desks. The laboratory experiments should be done individually (except group-experiments). The observations, experimental data, and answers to the questions should be documented instantly in the Manual in the course of the laboratory exercises. However, it is highly advisable to write the reaction equations in the Manual prior the given lab (at home). The right-hand pages of the Manual are left for that purpose. At the end of the exercise the students have to clean the glass vessels and other tools and set back the reagents’ flasks of to their place. Before leaving the laboratory students have to get a valid signature in the Manual from the supervisor.

4) In order to help the students’ work consultations can be organized. Dates of the consultations will be announced later, as agreed with the students.

Exam information

Requirements

1) Midterm Test

A midterm test will be written in the spring-term on

April 12-16, in lab time Organic chemistry. 30 points 45 minutes

(Lecture notes and lab topics)

Depending on the pandemic situation, this will be in written form (contact) during the labs or online (oral or written form). Smartphones, graphic calculators, netbooks, tablets and other text storage electronic devices are not allowed to use during the tests/exams. Cheating, plagiarism or use the above-mentioned devices are not tolerated (0 point), and the incidence will be promptly reported to Department of Student Affairs. Students who missed the midterm test due to illness (the medical certification must be sent to Dr. M. V. Pilipecz within 7 days after recovery) can get a make-up test at the end of term.

 

2) Examination

 

The semester has to be closed with an online, written examination consisting of simple-choice questions (35 simple choice questions, 35 minutes) which cover all subjects of lectures and laboratory exercises of the spring-term through Neptun Unipoll system. Students can collect 70 points with the exam.

 

The grade is determined by the sum of the points of this exam (70 points) and the points of the midterm test (30 points) according to the following table:

0 – 49 %                                              unsatisfactory (1)           

                                               50 – 62 %                                            pass (2)               

                                               63 – 74 %                                            fair (3)                                 

                                               75 – 87 %                                            good (4)                             

                                               88 – 100 %                                         excellent (5)

Cheating or plagiarism in any form is not tolerated (unsatisfactory), and the incidence will be promptly reported to Department of Student Affairs.

 

The Veterinary and Food Chemistry exams will be held on

  1. May 25th                              June 1th                                June 15td                             June 29th

from 14:00.
