Estonian Basic-School Biology Exam case studies
Estonian Basic-School Biology Exam · Put your knowledge to work in context.
The Estonian basic-school biology final examination (põhikooli bioloogia lõppeksam) is the school-leaving assessment in biology taken at the end of year 9, closing the compulsory basic-school programme. It is intended for students completing põhikool, for candidates who are retaking or improving a grade, and for anyone who needs evidence of basic-school biology competence for admission to gümnaasium or vocational study. The paper is written and paper-based, and its tasks are built on the national basic-school biology curriculum rather than on a single textbook. Expect open-ended and structured response items: explain a process in your own words, interpret a diagram, graph or data table, compare organisms, and reason from a short source text. Topics on this exam: Organisms and their diversity (taxonomy, bacteria, fungi, plants, animals), Cell biology and the organisation of living things (cell structure, tissues, organs, organ systems), Plant biology: structure, nutrition, growth, reproduction, Animal biology: structure, nutrition, respiration, circulation, reproduction, Human anatomy and physiology (organ systems and their functioning), Genetics and heredity (inheritance, variation, reproduction), Evolution and the history of life on Earth, Ecology and the environment (ecosystems, food webs, adaptation, human impact), and Scientific inquiry and practical skills (experiments, data interpretation, working with sources). The Estonian Basic-School Biology Exam case studies are 5 cases and about 2,294 words.
