Objectives
The general objective of the Fundamentals of Chemistry subject (which is part of Subject 3: Fundamentals of chemistry for environmental sciences, CCAA) is to put students in contact, for the first time in their Degree studies of CCAA, with the fundamental concepts of Chemistry. It is intended that the students become aware of the chemical basics that help to read into a large part of the environmental problems, mainly emphasis will be placed on aquatic environments. There will also be a brief introduction to chemical analysis, which is useful for the identification and quantification of different parameters or chemical compounds in water, soil and atmosphere.
The most specific objectives of the subject are the following:
1) To know the most relevant chemical fundamentals about the different systems in aqueous equilibrium and their application and consequences in the environment.
2) To acquire basic knowledge of the classic and current techniques used in the analysis of the main environmental compounds.
3) To develop the necessary skills to solve chemical equilibrium questions and introduce them to problem solving based on chemical analysis, if possible related to cases of environmental interest.
4) Develop the necessary skills to work in a laboratory.

Learning activities and methodology
| Title | Hours | ECTS | Learning outcomes |
|---|---|---|---|
| Tutoring | 2 | 0.08 | |
| Theoretical classes | 29 | 1.16 | |
| Solving problems | 43 | 1.72 | |
| Laboratory practices | 14 | 0.56 | |
| Study | 48 | 1.92 | |
| Solving problem classes | 10 | 0.4 |
Theory classes:
The teacher imparts the basic knowledge of the subject in the theory classes, making sure that its applicability to the resolution of problems related to the environment is clear. Although apparently the students do not have a very active participation in this type of teaching, their participation will be promoted to the maximum.
Group and/or individual activities or evidences will be carried out in the classroom and outside the classroom
Problem solving classes:
They are essential for putting into practice the knowledge acquired and knowing how to apply it to solving problems. Here it is essential that the students have a very active participation, solving (or at least trying to solve) the problems proposed before the face-to-face class.
Some problems will be developed by the students and others by the teachers on the board.
The teacher may also require the delivery of problems solved by the students for correction and evaluation.
Laboratory practices:
Laboratory practices are very important from a double perspective, on the one hand they allow students to see the application in the real world of the knowledge acquired.
On the other hand, they will allow them to acquire the experimental methodology and learn techniques that will be useful in their future professional life.
The laboratory practices are mandatory, and a lack of attendance implies a suspension from the subject.
Assessment
Continuous assessment activities
| Title | Weight | Hours | ECTS | Learning outcomes |
|---|---|---|---|---|
| Laboratory practices | 15% | 0 | 0 | CM05, SM09, SM10, SM11, SM12 |
| Partial exams | 60% | 4 | 0.16 | CM05, KM10, KM11, SM09, SM10, SM12 |
| Evidences | 25% | 0 | 0 | CM06, KM08, KM09, SM09, SM10, SM12 |
The overall grade of the subject will be obtained through the following weighting:
- Exams (60%)
- Evidence (25%)
- Laboratory practices (15%)
To consider the course passed, the overall grade must be equal to or higher than 5.0.
1. PARTIAL EXAMS (60%):
There will be two written partial exams (25-35% each, depending on the number of teaching hours included) on the concepts of theory and problems (they eliminate subject matter).
Minimum grade of 3.5 for each partial to be able to choose to pass by partial, and thus be able to calculate the final grade weighting the different assessment activities.
In order to be weighted with the Evidence and Laboratory grade, the weighted grade of the Partial Exams must be equal to or greater than 4.0.
Otherwise, the student will have to take the retrieval assesment for the partial with a lower grade, or for both partials, if that's the case. Partials can be recovered separately. The grade of the retrieval exam will replace the previous grade in the calculation of the final grade. The grade of the partials after the retrieval must also be equal to or higher than 4.0 to be able to calculate the weighted average with the other activities.
To be able to attend the recovery, the student must have previously been assessed for continuous assessment activities that are equivalent to 2/3 of the final grade.
2. EVIDENCE OF LEARNING (25%):
Group and/or individual assessment or self-assessment activities will be carried out in the classroom and/or outside the classroom. Deliverable evidence can include work, problems solved in class or at home, written tests in class with or without material, etc. They can be done in theory or problems class and they can be without notice.
A minimum grade of 4.0 is required in order to be weighted with the rest of the assessment activities. If the grade is lower than 4.0,there will be no possibility of passing the subject. Anevidence not presented will have a mark of 0. If the Evidences are not presented, the student will be classified as \"non-evaluable\", regardless of the grade of the partial exams.
The evidence cannot be recovered.
3. LABORATORY PRACTICES (15%):
Laboratory practices are mandatory for everyone.
The Internship Reports (to be prepared during the internship, and to be presented at the end of each internship session) will be assessed and scored. Prelabs will also be conducted (short initial tests to evaluate that each internship has been prepared correctly before entering the laboratory). Finally, the attitude and way of working in the laboratory will be taken into account, and the use of the laboratory notebook will be checked (it will be checked that an outline of the practice to be carried out is prepared in the notebook, as work prior to the internship, and the good collection of laboratory data will be reviewed). Weighting: Reports 80%, prelabs 10% and notebook/attitude 10%.
Minimum grade to be able to make a weighted average with the other assessment activities: 5.0.
In some partial exams there may be questions related to practices.
Failure to comply with the laboratory rules will result in fail the laboratory practices assessment and therefore with the impossibility of passing the subject.
There will be a session prior to the practices to explain how it works and that will be mandatory. Your attendance will be monitored and non-attendance will mean lowering the final practice grade by 1 point.
Not Assessed:
It will be considered "Not assessed" if the number of assessment activities carried out is less than 33% of the total of those scheduled in the subject.
Others:
Any act of copying in any of the assessment activities will mean a zero in the subject, regardless of other disciplinary implications.
In this subject, the use of Artificial Intelligence (AI) technologies is not allowed in any of its phases except for use as a study aid tool (always taking a critical attitude towards the veracity of the information provided by the AI). Any assessment activity (evidence or exams/controls) that include fragments generated with AI or there are indications of this fact, will be considered a lack of academic honesty and may lead to a partial or total penalty in the grade of the activity, or greater sanctions in serious cases.
UNIQUE ASSESSMENT:
The laboratoy practices (15%) attendance is compulsory for everyone (see the previous section where their operation and evaluation isexplained).
Regarding the other assessment activities, students who select the single assessment will take a single exam for the entire subject (60%), and will hand in all the evidences (25%) on the same day.
If the student do not pass the 4.0 grade in the exam, will have the option to go to a retrieval exam, as long as have previously submitted the other assessment activities: the evidences and the laboratory reports.
The retrieval grade will be used to calculate the weighted final grade (provided and when the evidence exceeds 4.0 and the laboratory practice grade exceeds 5.0).
