Course abstract

„Chemistry I” program focuses on generality of the chemical elements and compounds, transformations and properties of inorganic compounds. To improve knowledge and skills training materials, individual work-tasks and laboratory works which illustrate the dynamic nature of general, inorganic and environment chemistry in ones field are provided.

Learning outcomes and their assessment

Students are able to demonstrate their knowledge about properties of inorganic substances, regularities of transformation and their connection with forest science using the acquired theoretical foundations; knowledge base for easier acquisition of further study courses and self-improvement, as well as basic knowledge of methods for determining the qualitative and quantitative composition of chemical compounds – lectures and tests.
Students acquire skills to think analytically and creatively use the regularities of chemistry in practice, study process and professional activity - practical works and presentation of laboratory reports.
Competence to objectively evaluate new information, ability to independently find and select it, as well as to use it in solving issues related to chemistry in practical work - practical works and presentation of laboratory reports.

Requirements for awarding credit points

To receive a course grade, students must perform the following criteria:
• Students must perform all laboratory works and submit laboratory reports;
• Students must perfotm and submit home work.
• Students must write all tests during the semester (at least 4) and complete exam (at least 4).
If the average mark in the tests is not less than 7 and no more than two tests are overwritten, the exam may not be taken.

Description of the organization and tasks of students’ independent work

Preparing for test and practical works. Reading scientific literature, analysing results of experiments. Preparing of the home work.

Criteria for Evaluating Learning Outcomes

The final grade of the study course is calculated using a marking scheme:
•tests (80%);
•home work (20%);
All laboratory work must be inducted and included in laboratory work protocols. Students must have submitted and submitted homework. Each of the above course activities forms a certain percentage of the total mark.
The student must obtain a successful assessment (at least 4 points) for each course activity (tests and homework). The course is completed if all the above conditions are met.
