Objectives

Familiarize the student with laboratory security procedures – “the behavior in a laboratory”;
Acquisition of – elementary knowledge of management of fundamental chemical and physical variables. Introduce basic experimental concepts in microbiology.

Program

Chemistry Laboratory Techniques: Security, Solids and Liquids Manipulation; Volumes and Masses Measurement. Preparation and standardization of solutions. Volumetric and Gravimetric analysis. With these aims, we shall be doing the following practical assignments:
1 – Determination of concentration of solids suspended and dissolved in waste water
2 – Solutions preparation, dilution and standardization.
3 – Determination of the total and permanent water hardness (waste and for consumption)
4 – Determination of sulphates in water

Laboratory Techniques in Microbiology:
- Microorganism propagation;
- Aerobic and anaerobic cultivation of mixed bacterial cultures;
- Batch growth kinetics
- Observation of microorganisms that may exist in effluents


Solid products sample techniques and samples preparation.
Introduction to thermometric measurements.
Introduction to measurement of continual variables.

Physical characterization laboratory techniques:

1. Determination of densities using pycnometry
2. Determination of volume masses
3. Determination of water content
4. Determination of weight loss vs. temperature
5. Three different materials melting behaviour demonstration

Eligibility for exams

- Laboratory classes are compulsory for all the students, including the ones under article 4, items a) and b).
- The minimum grade of the theoretical component is 6 marks.
- The minimum grade of the practical component is 10 marks.

Calculation formula of final grade

Theoretical component: NT
Practical component: NP
NP=0.3*REL+0.7*AC
REL =0.5*REL1+0.5*REL2
Final grade of the course:
NF = 0.3*NT + 0.7 * NP
Where,
NF – Final grade of the course
NT – Test grade
AC – Weighed grade of the complete report of each of the practical assignments made (REL1 and REL2);

Examinations or Special Assignments

The final grade of the course includes the evaluation of the following components:

Theoretical component: one 50minute written test on the contents related to the practical assignments done in all the laboratories. The specific questions asked will be proportional to the weight of each module (or Laboratory) in the total practical assignments. It will have a classification (NT). Its weight in the final grade is 30%.

Practical component: Continuous evaluation of practical classes (AC) and two complete reports per group (REL); The page limit is 10.
AC – The students must have a laboratory exercise book where they will do a previous preparation of the assignment, take notes (data and comments), do the calculus and present a conclusion for each assignment (the previous preparation is done at home and the rest in the laboratory). The exercise book will be evaluated in each class, as well as the laboratory performance, which will function as a support to the attribution of the continuous evaluation grade (AC). As an alternative for the laboratory exercise book evaluation, the teachers can choose to demand the presentation of a short report (2 A4 pages maximum) on the seven days after the assignment is done.
REL – One of the reports will be obligatorily on the Chemistry Laboratory module (REL1) and the other will be picked out from the other modules (REL2); The final grade of the report will be calculated with the following formula:
REL = 0.5*REL1 + 0.5*REL2

The final practical grade (NP) will be calculated like this: NP = 0.3* REL + 0.7*AC

The final classification will be calculated by this formula:

Final Grade (NF) = 0.7*NP + 0.3* NT

Special assessment (TE, DA, ...)

N/A

Classification improvement

The theoretical component is the only grade which can be improved. This will be done with an exam in the re-sit examination period.

Observations

- The exam will be a 50 minute written test without consultation on the practical and theoretical themes.
- The students have to be evaluated in all the evaluation components.
