Chemistry C

Objectives

To provide introdutory knowledge in chemistry to students with different backgrounds.

The student should learn the contents of General Chemistry included in the program, to know how to do the experimental work and solve the proposed problems.

On successful completion of the module, students will be able to
a) apply fundamental Chemistry concepts in Engineering subjects.
b) understand simple chemical phenomena with impact in society.
b) solve simple problems in thermochemistry, chemical thermodynamics, ideal gases, chemical kinetics, acids and bases, solubility, electrochemistry and organic chemistry.
c) perform calculations related to chemical phenomena and the corresponding physical measurements.
d) perform simple lab tasks – weighting, transfer of liquids and solids, titrations, measurement of absorvances and determination of concentrations.
e) critically assess results.
On successful completion of the module, students will have improved interpersonal skills and the ability to study alone.

Teaching method

This course uses Team-Based Learning, TBL, http://www.teambasedlearning.org .

The unit is organised in 5 modules. Before each module, students are provided with the learning material and a list of specific objectives. Before the first class of each module, each student must answer an individual test (Readiness Assurance Test). The same test is answer by teams in class, followed by a mini-lecture to solve the test, discuss doubts and reinforce the most difficult points.

In the other classes of the module, teams are challenged with application activities, including lab works.

Evaluation method

Class evaluation: 50%,  Final exam (or 2 written tests): 50%

Minimum mark in exam (or tests): 9,5.

Mark for class activities=average of individual tests (25%) and team results (20% labs, 80% team works). Mark corrected by peer evaluation (team mark x points received by colleagues/100).
