5th Grade STAAR Science fully solved to pass 2023 Mass - correct answer A measure of the amount of matter in an object Physical State - correct answer The classification of matter as a solid, a liquid or a gas Properties - correct answer Appearances of an object including: mass, magnetism, physical state, relative density, solubility, and the ability to insulate or conduct heat or electricity Matter - correct answer Anything that has mass and takes up space Solubility - correct answer The ability of a substance to dissolve in another substance Dissolve - correct answer When a substance breaks down until it can no longer be seen Relative Density - correct answer floating or sinking when compared to water, greater density than water (sinks) and less density (floats) Conductor - correct answer A material that allows heat and electricity to pass through it. Insulator - correct answer A material that does not allow heat or electricity to move through it easily. Thermal Energy - correct answer Heat energy Boiling Point - correct answer The temperature point at which a liquid changes to a gas (100 degrees celcius) Freezing Point - correct answer The temperature point at which a liquid changes into a solid (0 degrees celcius) Melting Point - correct answer The temperature point at which a solid becomes a liquid (0 degrees celcius) Hot Plate - correct answer a lab tool used to heat substances Thermometer - correct answer An instrument used to measure temperature Celcius - correct answer Metric temperature scale on which water freezes at 0 degrees and boils at 100 degrees Mixture - correct answer When two or more substances are combined and they may retain some of their physical properties Solution - correct answer A mixture that forms when one substance dissolves another. Mechanical Energy - correct answer Kinetic or potential energy associated with the motion or position of an object (Machines) Light Energy - correct answer Energy in the form of moving waves of light (Energy we see) Sound Energy - correct answer energy of vibrations carried by air, water, or other matter (energy we hear) Electrical Energy - correct answer Energy made available by the flow of electric charge through a conductor Circuit - correct answer A pathway on which electrons flow through a conductor
