1. SECOND LAW OF THERMODYNAMICS

2. Studens have stated the first law of thermodynamics and defined the concepts: Studens have stated the first law of thermodynamics and defined the concepts: heat, thermodynamic system, internal energy and work heat, thermodynamic system, internal energy and work done in thermodynamic system. done in thermodynamic system. After separation into groups students got working sheets and assignments. After separation into groups students got working sheets and assignments.

3. Member of each group presented their conclusions and wrote them on the blackboard. Member of each group presented their conclusions and wrote them on the blackboard. For homework they had to find some examples that prove those conclusions. For homework they had to find some examples that prove those conclusions.

4. One student presented his homework which included example of irreverzibile process. Other students thought of more natural irreversible processes. After showing students PowerPoint presentation about entropy they defined entropy as general law. The total entropy of the universe is constantly INCREASING!!!

5. To understand concept of equilibrium and probability in interpretation of entropy students performed experiment. To understand concept of equilibrium and probability in interpretation of entropy students performed experiment.

6. All the results of experiments have been put in the table and then they´ve put that data on millimeter paper.

8. On prepared transparent sheet for graphoscope with axes, two students have done plotting during the class.

9. These were conclusions : the most probable state is 5 heads and 5 tails the most probable state is 5 heads and 5 tails the least probable state is all heads or all tails the least probable state is all heads or all tails

10. The second law of thermodynamics, in terms of probability, reduces to the statement that those processes occur which are most probable. That way students learned and understood concept of probability in interpretation of entropy.

11. Discussing about heat death of Universe students got a greater insight into concept of entropy and analogy that can be used in many other scinces.

12. For homework they explored differences beetween theory of evolution and concept of entropy. For homework they explored differences beetween theory of evolution and concept of entropy. Then they wrote an individual essay on: Then they wrote an individual essay on: „Evolution Vs. Second Law Of Thermodynamics“ „Evolution Vs. Second Law Of Thermodynamics“ using previous knowledge. using previous knowledge.

13. Students discussed about global warming and thermal pollution, after watching a short movie about global warming. Students discussed about global warming and thermal pollution, after watching a short movie about global warming. The aim was to rise awarenes about human impact on nature and climate changes. The aim was to rise awarenes about human impact on nature and climate changes.

15. The table of energy resources was showen to students and we have discussed each source. students and we have discussed each source. The aim was to rise awareness about preserving environment and future of energy resources as environment and future of energy resources as well as of the planet. well as of the planet. In course evaluation form they wrote that they liked that way of work.
