(3) Scientific investigation and reasoning. The student uses critical thinking and scientific problem
solving to make informed decisions. The student is expected to:
(A) analyze, evaluate, and critique scientific explanations by using evidence, logical
reasoning, and experimental and observational testing;
(B) draw or develop a model that represents how something that cannot be seen such as the
Sun, Earth, and Moon system and formation of sedimentary rock works or looks; and
(C) connect grade-level appropriate science concepts with the history of science, science
careers, and contributions of scientists.
(4) Scientific investigation and reasoning. The student knows how to use a variety of tools and
methods to conduct science inquiry. The student is expected to
collect, record, and analyze information using tools, including calculators, microscopes,
cameras, computers, hand lenses, metric rulers, Celsius thermometers, prisms, mirrors,
balances, spring scales, graduated cylinders, beakers, hot plates, meter sticks, magnets,
collecting nets, and notebooks; timing devices; and materials to support observations of
habitats or organisms such as terrariums and aquariums.
(5) Matter and energy. The student knows that matter has measurable physical properties and those
properties determine how matter is classified, changed, and used. The student is expected to:
(A) classify matter based on measurable, testable, and observable physical properties,
including mass, magnetism, physical state (solid, liquid, and gas), relative density
(sinking and floating using water as a reference point), solubility in water, and the ability
to conduct or insulate thermal energy or electric energy;
(B) demonstrate that some mixtures maintain physical properties of their ingredients such as
iron filings and sand and sand and water; and
(C) identify changes that can occur in the physical properties of the ingredients of solutions
such as dissolving salt in water or adding lemon juice to water.
(6) Force, motion, and energy. The student knows that energy occurs in many forms and can be
observed in cycles, patterns, and systems. The student is expected to:
(A) explore the uses of energy, including mechanical, light, thermal, electrical, and sound
energy;
(B) demonstrate that the flow of electricity in closed circuits can produce light, heat, or
sound;
(C) demonstrate that light travels in a straight line until it strikes an object and is reflected or
travels through one medium to another and is refracted; and
(D) design a simple experimental investigation that tests the effect of force on an object.
(7) Earth and space. The student knows Earth's surface is constantly changing and consists of useful
resources. The student is expected to:
(A) explore the processes that led to the formation of sedimentary rocks and fossil fuels; and
(B) recognize how landforms such as deltas, canyons, and sand dunes are the result of
changes to Earth's surface by wind, water, or ice.
(8) Earth and space. The student knows that there are recognizable patterns in the natural world and
among the Sun, Earth, and Moon system. The student is expected to:
(A) differentiate between weather and climate;
