1 The student will demonstrate an understanding of the properties of matter and energy and their interactions.
5.5 The student knows that matter has measurable physical properties and those properties determine how matter is classified, changed, and used.
A classify matter based on physical properties, including mass, magnetism, physical state (solid, liquid, and gas), relative density (sinking and floating), solubility in water, and the ability to conduct or insulate thermal energy or electric energy;
2 The student will demonstrate an understanding of force, motion, and energy and their relationships.
5.6 The student knows that energy occurs in many forms and can be observed in cycles, patterns, and systems.
A explore the uses of energy, including mechanical, light, thermal, electrical, and sound energy;
B demonstrate that the flow of electricity in circuits requires a complete path through which an electric current can pass and can produce light, heat, and sound;
C demonstrate that light travels in a straight line until it strikes an object or travels through one medium to another and demonstrate that light can be reflected such as the use of mirrors or other shiny surfaces and refracted such as the appearance of an object when observed through water; and
D design an experiment that tests the effect of force on an object.
These skills will not be listed under a separate reporting category. Instead, they will be incorporated into at least 40% of the test questions in reporting categories 1–4 and will be identified along with content standards.
5.1 The student conducts classroom and outdoor investigations following home and school safety procedures and environmentally appropriate and ethical practices.
A demonstrate safe practices and the use of safety equipment as described in the Texas Safety Standards during classroom and outdoor investigations; and
B make informed choices in the conservation, disposal, and recycling of materials.
5.2 The student uses scientific methods during laboratory and outdoor investigations.
A describe, plan, and implement simple experimental investigations testing one variable;
B ask well-defined questions, formulate testable hypotheses, and select and use appropriate equipment and technology;
C collect information by detailed observations and accurate measuring;
5.3 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 evaluate the accuracy of the information related to promotional materials for products and services such as nutritional labels;
C draw or develop a model that represents how something works or looks that cannot be seen such as how a soda dispensing machine works; and
D connect grade-level appropriate science concepts with the history of science, science careers, and contributions of scientists.
5.4 The student knows how to use a variety of tools and methods to conduct science inquiry.
A collect, record, and analyze information using tools, including calculators, microscopes, cameras, computers, hand lenses, metric rulers, Celsius thermometers, prisms, mirrors, pan balances, triple beam balances, spring scales, graduated cylinders, beakers, hot plates, meter sticks, magnets, collecting nets, and notebooks; timing devices, including clocks and stopwatches; and materials to support observations of habitats or organisms such as terrariums and aquariums; and
