Biology Teaching Program A Local Ecosystem PRELIMINARY BIOLOGY CORE MODULE 8.2 This teaching program has been prepared as a starting point to assist teachers in the creation of lesson plans, and is a suggested guide only. It is not prescriptive, nor is it endorsed by the Board of Studies. The program has been developed with reference to specific components of the syllabus, and is intended to aid teachers in incorporating these components into their lessons. References to syllabus points within the program are numbered for ease of reference: these numbers correspond to the syllabus outline document ‘Numbered Syllabus References’, which derives from the Board of Studies (NSW) Biology Stage 6 Syllabus (Amended October 2002). Each number represents a bullet point from this document. The order and content of lessons may require modification to suit the individual requirements of teachers and students. A LOCAL ECOSYSTEM – PRELIM BIOLOGY CORE MODULE 8.2 Lesson 1 Students Learn to (KNOW) Compare the abiotic characteristics of aquatic and terrestrial environments. (1) Key Lesson Content Learning Style Evaluation Informal Ass Outcomes Define abiotic factors as factors that are non-living parts of the environment. For example water, temperature etc. The distribution, diversity and numbers of plants and animals found in ecosystems are determined by biotic and abiotic factors.
