E perform repeated investigations to increase the reliability of results; and
F communicate valid, oral, and written results supported by data.
3 The student uses critical thinking and scientific problem solving to make informed decisions.
A in all fields of science, analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, including examining all sides of scientific evidence of those scientific explanations, so as to encourage critical thinking by the student;
B draw inferences and evaluate accuracy of services and product claims found in advertisements and labels such as for toys, food, and sunscreen;
C represent the natural world using models such as rivers, stream tables, or fossils and identify their limitations, including accuracy and size; and
D connect grade-level appropriate science concepts with the history of science, science careers, and contributions of scientists.
4 The student knows how to use a variety of tools, materials, equipment, and models to conduct science inquiry.
A collect, record, and analyze information using tools, including calculators, microscopes, cameras, computers, hand lenses, metric rulers, Celsius thermometers, mirrors, spring scales, pan balances, triple beam balances, graduated cylinders, beakers, hot plates, meter sticks, compasses, magnets, collecting nets, and notebooks; timing devices, including clocks and stopwatches; and materials to support observation of habitats of organisms such as terrariums and aquariums; and
B demonstrate that some likenesses between parents and offspring are inherited, passed from generation to generation such as eye color in humans or shapes of leaves in plants. Other likenesses are learned such as table manners or reading a book and seals balancing balls on their noses; and
