Science
| Term | Definition |
|---|---|
| Quantitative Observation | Made by gathering information that can be recorded using measurements and units |
| Qualitative Observation | Made by gathering information that can be recorded using descriptive language |
| Inference | Not a fact, but an interpretation of what the direct observations mean |
| Scientific Law | Describes what scientists expect to happen every time under a particular set of conditions |
| Constant | Part of an experiment that is held in the same condition for control and experimental |
| Variable | Part of the experiment that changes |
| Independent Variable (MV) | A factor in a controlled experiment that is intentionally changed by the experimenter |
| Scientific Theory | A well tested explanation for a wide range of observations or experimental results |
| Dependent Variable (RV) | A resulting factor in a controlled experiment that is observed and measured to see if it changes due to the manipulation of another variable |
| Inquiry | To ask for information |
| Experiment | A course of action completed in order to test a hypothesis |
| Control | A standard to which all other levels are compared in a scientific experiment |
| Matter | Anything that has mass and takes up space |
| Physical Property | Any change that alters the form of appearance of matter but does not make any substance in the matter into a different substance or a characteristic of a pure substance that can be observed without changing it into another substance |
| Chemical Property | A change in matter that produces one or more new substances or a characteristic of a pure substance that describes its ability to change into different substances |
| Weight | The amount of gravity on an object |
| Mass | The amount of matter (atoms) in a substance; measured in grams and kilograms |
| Grams | Unit of mass or an SI unit to measure mass; 1g = 0.001kg; there are 1000g in 1 kilogram |
| Accuracy | The quality or state of being correct or precise |
| Calibrate | To mark off lines on measuring equipment for the desired unit |
| Graduated Cylinder | Equipment use to measure liquid volume |
| International System of Measurement | Base unit for measuring mass (kilogram) |
| Liquid | A state of matter having definite volume, indefinite shape, with particles touching, and sliding around each other |
| Mass | The amount of matter in an object |
| Matter | Anything that has mass and takes up space |
| Meniscus | The curve on the upper surface of a liquid in a container caused by surface tension |
| Newton-a unit of measurement | A unit of force required to move 1 kilogram 1 meter |
| Precision | The quality, condition, or fact of being exact and accurate |
| Triple beam balance | Scale used to measure accurate quantities of mass |
| Unit | A single, undivided whole; a quantity chosen as a standard for measurement |
| Volume | The amount of space an object takes up or the amount of space a container holds |
| Weight | The measure of the pull of gravity on a substance |
| Mixture | Matter that consists of two or more substances not chemically combined |
| Matter | Anything that has mass and volume(takes up space) |
| Pure Substance | A substance made of only one kind of material having definite proportional amounts and properties |
| Element | The simplest type of pure substance |
| Compound | Two or more elements chemically combined |
| Homogeneous mixture | Two or more substances not chemically combined, but appearing to be evenly blended |
| Heterogeneous mixture | Two or more substances not chemically combined, and appearing non-uniform with physically distinct substances included |
| Centimeter cubed (cm3) | A unit of volume derived from length times width times height |
| Compress | To squeeze or press together |
| Condensation Point | Temperature at which a gas to turn liquid |
| Conductor | A material that does allow electricity or heat to pass through easily |
| Density | An object’s mass compared to its volume. Mass divided by volume is density |
| Deposition | A gas changing into a solid without changing into a liquid |
| Dissolve | To break into pieces too small to be seen |
| Ductile | Able to be pulled into long, thin wires |
| Freezing Point | Temperature at which a liquid turns to solid |
| Gas | A state of matter having indefinite volume, indefinite shape, with particles bouncing around and not touching each other |
| Gram per centimeter cubed | g/cm3; a derived unit used to measure density of a solid |
| Gram per milliliter | g/mL; a derived unit used to measure density of a liquid |
| Insulator | A material that does not allow electricity or heat to pass through easily |
| Kilogram | The SI base unit to measure mass; 1 kg = 1000g |
| Kinetic Theory | A physics theory that all matter is made of moving particles in random motion |
| Liter | The SI unit to measure volume of liquids |
| Luster | Shininess; the property of something that shines with reflected light |
| Magnetic | Material that is attracted to magnets |
| Malleable | Able to be hammered or pressed into flat sheets |
| Melting Point | Temperature at which a solid turns to liquid |
| Milliliter | An SI unit to measure volume of liquids; 0.001 of a liter; there are 1000 mL in 1 Liter. |
| Phases of matter | Solids, liquids, gases, and plasma; also called states of matter |
| Plasma | A state of matter consisting of ionized (electrically charged) particles |
| Solid | A state of matter having definite volume, definite shape, with particles vibrating, touching and locked into place |
| Soluble | Able to dissolve |
| States of matter | Solids, liquids, gases, and plasma; also called phases of matter |
| Sublimation | Turning from solid to gas without turning into a liquid |
| Texture | How something feels, especially whether it is bumpy or smooth |
