For example, predictive models of climate change may give very different results. Transformations lead to an interaction within a system in the formation of a new end product, or involve a change of state.
These include Adobe pdf handouts of presentation material, Quicktime movies of the same and also pdf versions of the entire website topic.
In practice, some models require approximation techniques to be used. A static equilibrium, in which there is no change, should be appreciated as a condition to which natural systems can be compared. Both laws should be examined in relation to the energy transformations and maintenance of order in living systems.
Strictly, closed systems do not occur naturally on Earth, but all the global cycles of matter, for example,the water and nitrogen cycles, approximate to closed systems.
However, as the course aims to foster an international perspective, awareness of local and global environmental concerns and an understanding of the scientific methods, a course that shares these aims would be good preparation.
All materials are sorted into the Topic order as found within the IB syllabus for each subject, so hopefully making it easy for students taking IB courses to follow in the order in which their particular course is being delivered.
The ecosystem[ edit ]. In contrast, an aquarium may be a relatively simple ecosystem but demonstrates many ecological concepts. These are what the IB has designated as objectives for the unit.
Key features of the curriculum and assessment models Available only at standard level SL The minimum prescribed number of hours is A hands-on approach to the course delivery is emphasised. Negative feedback is a self-regulating method of control leading to the maintenance of a steady-state equilibrium—it counteracts deviation, for example, predator—prey relationships.
This site is designed to help students who are studying Post 16 16year old plus Environmental Science and the Ecology sections in a Biology course.
Students are assessed both externally and internally External assessment consists of two written papers and provides opportunities for students to demonstrate an understanding through the application, use, synthesis, analysis and evaluation of environmental issues, information, concepts, methods, techniques and explanations.

As energy is dispersed to the environment, there will always be a reduction in the amount of energy pased on to the next trophic level.
During the course, students will study eight different topics. The relative stability of an equilibrium—the tendency of the system to return to that original equilibrium following disturbance, rather than adopting a new one— should also be understood.
When energy is transformed into work, some energy is always dissipated lost to the environment as waste heat.
