5.5 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: 

5.5A 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

5.6 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:

5.6A explore the uses of energy, including mechanical, light, thermal, electrical, and sound energy

5.6B demonstrate that the flow of electricity in closed circuits can produce light, heat, or sound

5.6C 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

5.3C connect grade-level appropriate science concepts with the history of science, science careers, and contribution of a scientist.
