Molecule | The smallest unit of a substance that is the combination of one or more atoms |
Mutation | A change in the DNA of an organism; substitution, deletion, insertion Mutualism |
Natural selection | The process in which some organisms live and reproduce and others die before reproducing |
Newton | Sir Isaac Newton, a scientist who made hundreds of contributions to science like the law of gravity and his three major laws of physics; a Newton is a measure of force |
Newton's 1st Law | An object at rest stays at rest and an object in motion stays in motion unless acted upon by an outside force |
Newton's 2nd Law | The net force on an object is equal to the acceleration on that object times the mass of the object |
Newton's 3rd Law | Every reaction has an equal and opposite reaction |
Nonmetal | A chemical element from the right side of the periodic table that is brittle and does not conduct electricity well |
Nuclear decay | This happens when the nucleus of an atom breaks apart; usually, neutrons and protons leave the nucleus |
Nuclear energy | Energy that is produced by fission or fusion reactions |
Nuclear reaction | A reaction that happens in the nucleus of an atom; fission, fusion |
Nucleic acid | In the nucleus of a cell, there are two major types of nucleic acids: DNA and RNA |
Nucleus | 3In biology, this refers to the middle of a cell; in physical science, this refers to the center of an atom |
Organic | moleculeA molecule that contains carbon atoms bonded together |
Organism | A living thing that can live and reproduce independently |
Ozone | A form of oxygen that, in the atmosphere, protects living things from ultraviolet rays |
Parasitism | A relationship in which one organism lives in or on another organism and benefits from that relationship while the host organism is harmed by it |
Peer review | A method of selecting essays to be published where a group of peers review and make comments about the submitted essays |
Periodic table | An arrangement of chemical elements based on their atomic numbers and similarity of properties |
pH scale | Measures the strength of acids and bases; an acid has a number below 7, a base has a number above 7 and neutral materials have a pH of 7 (like water) |
Phenotype | The physical expression (what can be seen) of a genetic characteristic; brown eyes, black hair |
Photosynthesis | The process that happens in plants and some other organisms which takes the sun's energy and turns it into usable energy; 6CO2 + 6H2O + Light è C6H12O6 (glucose) + 6O2 |
Physical change | A change in a substance that results in a different form of the substance and can be undone |
Physical property | A characteristic of a substance that can be observed; color, taste, texture, density |
Physical science | Any of the sciences, such as physics, chemistry, astronomy, and geology, that discusses the nature and properties of energy and nonliving matter |
Plastic | A material that can be molded and formed into objects and films |
Plate tectonics | The theory that the earth's surface is divided into a few large, thick plates that are constantly moving |
Potential energy | Stored energy; energy that is released and then becomes kinetic energy Predation |
Prokaryote | A type of living thing that is single-celled and has no true nucleus |
Protein synthesis | The creation of proteins in the cell from DNA |
Protein | A sequence of amino acids |
Proton | A positively-charged particle in the nucleus of an atom |
Pure substance | eA substance that has an identical chemical composition in every part |
Radiation | Energy that is transmitted in the form of rays or waves or particles; when talking about heat, this is when heat spreads out from a central source |
Radio wave | A type of electromagnetic radiation that has very low energy and a very long wavelength (can be 10 – 20 feet long); used for cell phones and radios of all kinds |
Radioactive substance | A type of substance that releases neutrons and protons from its nucleus |
Radiometric dating | Determining the age of a rock or fossil based on the amount of one isotope compared with another isotope; ex: the amount of carbon-14 versus the amount of carbon-12 can determine how old something is because carbon-14 breaks down to carbon-12 over time |
Recessive | A genetic characteristic that is only expressed by the organism if there is no dominant characteristic present |
Recycle | To break down a material so that it can be reused instead of throwing it away Reproduction |
Sea-floor spreading | In geology, when oceanic plates move apart, the middle fills in with magma which cools and forms new sea floor |
Semiconductor | A type of material that allows electricity to flow with average resistance |
Sex-linked trait | A genetic characteristic that is present only on the X (or in some cases, the Y) chromosome and so behaves differently in males and females Sexual |
Solid | One of the basic states of matter which has a definite shape and volume |
Species | A very specific classification of organisms; all members of a species can mate together |
Speed | The amount of distance an object travels divided by the amount of time it takes; He traveled 30 mph |
Stem cell | A type of cell that can turn into any other type of cell |
Superconductor | A type of material that allows electricity to flow with no resistance |
Sustainable agriculture | Agriculture that is done so the land is used well and can continue on forever |
Symbiosis | A relationship between two or more organisms |
Synthesis | The combination of two or more things or concepts TechnologyThe application of science to solve a particular problem |
Temperature | The measurement of the average thermal energy of a system |
Theory | A well proven explanation of some part of the natural world |
Thermal energy | Heat |
Total mass | The combination of all of the masses of everything that is being considered Ultraviolet |
Unbalanced force | A force that is not balanced out by an opposite force; She was pushing against the wall, but when the wall fell it became an unbalanced force! |
Unstable nuclei | More than one nucleus (nuclei) that break down very quickly to smaller nuclei |
Variation | Something that has changed; in biology, this refers to the genetic difference between individuals |
Velocity | The distance that an object travels over a certain amount of time and in a certain direction; He traveled at 30 mph south |
Virus | A small particle that contains DNA or RNA and is able to reproduce only inside of a living cell |
visible ligh | A form of electromagnetic radiation that is visible to the human eye (other organisms are capable of seeing some infrared and ultraviolet radiation) |
Volume | The amount of space an object takes up |
Wave | A movement up and down or back and forth |
Wavelength | Refers to the length of a single wave (back and forth); can be calculated from the crest of one wave to the crest of the next |
Weight | The combination of the mass and the force of gravity on an object |
X-rays | A form of electromagnetic radiation that has low energy and is used in medical equipment |
