CHARLES CITY SCIENCE STANDARDS Alternative Biology Standards and Benchmarks MC/GF = Multicultual Gender Fair Approaches; CE=Career Education; GE=Global Education ITBS/ITED 1. Understands the nature of scientific inquiry MC/GF CE GE MC/GF CE GE Knows that in science, the testing, revising, and occasional discarding of theories, new and old, never ends; this ongoing process leads to an increasingly better understanding of how things work in the world, but not to absolute truth Designs and conducts scientific investigations by identifying and clarifying the questions, method, controls and independent and dependent variables; organizing and displaying data; revising methods and explanation; presenting the results; and receiving critical response from others Knows that many scientific investigations require the contributions of individuals from different disciplines 3. Understands diversity and unity that characterize life Knows that evidence for simple, one-celled forms of life such as bacteria and algae, extends back more than 3.5 billion years; the evolution of life resulted in dramatic changes in the composition of the Earth’s atmosphere, which did not originally contain oxygen Knows that initially most cells have the ability to become any kind of cell because they contain the same genetic information and they also retain the basic information that allows them to reproduce themselves Knows that organisms are classified into a hierarchy of groups and subgroups based on their similarities and reflecting their evolutionary relationships; Knows that the variation of organisms within a species increases the likelihood that at least some members of the species will survive under changed environmental conditions, and a great diversity of species increases the chance that at least come living things will survive Knows that the basic idea of evolution is that the Earth’s present-day life forms have evolved from earlier, distinctly different species Knows that the fact that the human body is formed from cells containing two copies of each chromosomes (and, therefore, two copies of each gene); this explains many feature of human heredity Knows that organisms both cooperate and compete in ecosystems; the interrelationships and inter dependencies of these organisms may generate ecosystems that are stable for hundreds or thousands of years Knows that humans are increasingly modifying ecosystems as a result of population growth, technology, and consumption; human destruction of habitats through direct harvesting, pollution, atmospheric changes, and other factors is threatening global stability, and if not addressed, ecosystems will be irreversibly damaged Knows that plant cells contain chloroplasts, the sites of photosynthesis, which provide the vital connection between the Sun and the energy needs of living systems 6. Understands the relationships of science, technology, and social perspectives MC/GF CE Knows that science and technology are pursed for different purposes GE BIOLOGY UNITS UNIT 1-“5-4-3-2-1.....1-2-3-4-5”: Scientific Method; Nature of Science; Science as Inquiry; Lab Safety 3 weeks UNIT 2- “Big Things come in Little Packages”: Basic unit of structure and function; organelles; cell processes; specialization and differentiation; plant structure and function; photosynthesis 5 weeks UNIT 3- “The Circle of Life”: DNA-what it is, functions, processes; punnett squares 4 weeks Genetic fundamentals; UNIT 4-”N.E.R.D.
