Since it is a first year course, there are no academic prerequisites to enroll.
In any case, it must be taken into account that the subject contains a large part of laboratory sessions and requires a specific regulation. The behavior in the laboratory must follow the Safety Standards in the Teaching Laboratories published by the Chemistry Department.
Before starting the course, students have to fill in the security test that appears on the "Campus Virtual" and, once passed, print and sign the sheet that accredits it. This sheet must be delivered the first day of the laboratory. Without this document you can not do the practices.
The rules can be found at the following address: http://www.uab.cat/doc/DOC_Normativa_Segur_Lab_Docent
During practices, students must wear the lab coat and approved safety glasses. In addition to the usual writing tools, they have to carry (and know how it works) a scientific calculator that can do regression calculations. It is advisable that they go in the laboratory with a laptop to do calculations with Excel

The general objective of this part of the subject is to provide a basis for students in transversal computer skills in science and specific to the field of chemistry. It is intended for students to acquire skills in the management and analysis of experimental data, in the visualization and manipulation of three-dimensional and electronic structures and finally in programming.
The subject consists of two differentiated parts: Experimentation in the laboratory (5 ECTS) and Computer Resources (3 ECTS).

The subject "Experimentation and Computer Resources" has two main parts. One of experimentation that focuses on the work of chemical laboratories. The other of computer resources that is oriented to the acquisition of knowledge and skills of fundamental computer tools to perform data analysis, carry out searches for bibliographic holdings, introduce advanced concepts of security and generation of supporting materials. chemical field (molecular drawing, models).
Experimentation.
The subject "Experimentationand Computer Resources" (8 ECTS), together with the subject "Fundamentals of Chemistry I" and "Fundamentals of Chemistry II (16 ECTS), is part of the" Chemistry "subject of the Chemistry degree, which has a total of 24 ECTS of a basic nature and located in the first year of the Degree.The subjects are totally independent with respect to the evaluation, but they are coordinated, so that the evaluation of the part of the subjects "Fundamentals of Chemistry I and II "which is related to the practices, is done after finishing the corresponding block of practices, so the practices benefit from having the theoretical explanations close to time and serve to finish understanding the theory.Computer Resources.
Due to the different levels of complexity of the topics covered in each block, teaching will be given in various ways.
The standard procedure for most practices in blocks A, B and C will be:
1. A few days before class, students receive introductory material to the theoretical and practical knowledge of the practice. (Introductory videos by teachers, study documents, internet links, etc.). It can include some basic exercises to solve.
2. On the scheduled day of the classes, the teachers briefly recapitulate the fundamental concepts and develop practical cases.
3. At the end of the class, students will have to solve an online test in person and lasting between 10 and 20 minutes. It is not allowed to take the test from any other classroom or place other than the one assigned by the face-to-face class.
For block D (programming), introductory videos will also be offered but the face-to-face class will propose an extensive presentation and cases to be developed together with the teacher for a better homogeneity in overcoming the contents and competences. Occasional work, face-to-face or non-face-to-face, must be solved and submitted. Depending on the degree of comprehension or progress, the student may have the option of more or less complex statements. Finally, a group work will be requested with its presentation on the last day of the blog.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Evaluation of all ERI
All the activities that are carried out count for the evaluation.
Both parts of the course have an individual and independent assessment. The final grade is the average of the marks of the two parts of the subject, weighted by the number of credits of each part. A grade of "not presented" will only be possible for cases where the student has not submitted the assessments of more than 4 practices (approximately 20%). It is necessary to pass both parts to pass the course. The pass is obtained with a 5/10.
Regarding the part of Experimentation in the laboratory: A system of continuous evaluation is followed, without the possibility of re-evaluation with a special work or examination. The minimum grade to pass it is 5 points (out of 10). In this note the most important weight are the reports that are delivered at the end of each practice (weight 80%). The report must put the experimental results obtained into practice and answer the questions asked, leaving a record of the necessary graphs and calculations. The methodology followed for the answers, the way in which the answers are communicated and the goodness of the experimental data found are assessed. Preliminary tests will also be taken into account (before starting each practice) to show that the reports and the work attitude in the laboratory have been read (weight 20%). Failure to attend the correction and comment session of the blog practices has a penalty of 1 point (out of 10) on the blog note. The final grade for this part will be the average of the grades for all blocks.
Attendance is mandatory. An unjustified misconduct implies a zero of practice.
Laboratory Safety Warning: A student who is involved in an incident that may have serious safety consequences may be expelled from the laboratory and suspended from thesubject.
Regarding the part of Computer Resources:
The quizzes in block A, B and C have the same weighting as 1. For block D, the non-face-to-face assessments will weigh 0.5 and the final group work 2.5. Non-contact assignments will be assessed in proportion to the difficulty of the chosen statement.
The internships are compulsory and can be done individually or in groups as indicated by the teacher. An unjustified lack of attendance implies a zero in practice. The teaching staff reserves the right to carry out additional assessments to those established at the beginning of the course. It is emphasized that face-to-face tests can only be taken in the classroom on the day of the practice (with the exception of indications to the contrary by the teacher). Any attempt to perform the test from another location will be valued at zero. Repetitive attempts of this kind or other types of fraud will lead to the immediate suspension of the subject.
The non-delivery of 4 or more works of the 20 implies not passing of this part and therefore of all the matter.
