| Allele | | How widely a scientific investigation applies to situations other than the specific ones scientists tested |
| Asexual Reproduction | | Positively charged subatomic particle inside the nucleus of an atom |
| Atom | | Central sphere of an atom made of protons and neutrons, with electrons orbiting |
| Cell | | A test or manipulation in which a scientist keeps all variables (possible factors that could affect the outcome of the test) the same except for the one under investigation |
| Chemical Bonding | | A different version of the same gene |
| Classification | | Neutal subatomic particle inside the nucleus of an atom |
| Diversity | | A procedure for determining the evidence in support of a hypothesis |
| Electron | | Promoting the use and/or purchase of remedies even when there is no scientific evidence or plausible rationale for their effectiveness |
| Element | | Formed through the chemical bonding of atoms |
| Evolution | | Negatively charged subatomic particle that orbits the nucleus of an atom |
| Macromolecule | | A procedure that sets up the conditions the predictions require |
| Metabolism | | the idea that effects in the natural world all have causes, rather than supernatural ones |
| Molecule | | Smallest unit of life |
| Mutation | | The unique classification of each species from kingdom to species |
| Natural Selection | | A substance composed of only one type of atom |
| Neutron | | A physical change in the DNA |
| Nucleus | | every event or outcome in nature has a source; if a scientist sets up the correct conditions, the result can be predicted in advance |
| Orbital | | The outermost shell of an atom that can accommodate a specific number of electrons |
| Proton | | The building block of every physical thing in existence |
| Scientific Name | | Proteins that make it easier for chemical reactions to occur |
| Sexual Reproduction | | The theory that explains how all living organisms are related and how existing populations adapt to their environments and how new species arise |
| Cause and Effect | | The variety of life forms in the natural world |
| Controlled Experiment | | Sharing of electrons in the outer shell of more than one atom |
| Empirical Evidence | | Something that has actual existence |
| Fact | | The term Darwin used to describe the mechanism by which species change over time; conditions in the natural world select which individuals will survive and reproduce |
| Falsifiable | | Reproduction that occurs when an egg from a female fuses with a sperm cell from a male to form a new individual |
| Generality | | A living thing that cannot be seen without the use of a microscope, such as bacteria |
| Hypothesis | | An idea, supported by evidence, whichprovides a bigger picture than a hypothesis of how some aspects of nature works; it may weave together supporting evidence from several scientific fields |
| Materialism | | information that one gets from direct observation from experience, or from the results of experiments and other tests of hypotheses |
| Enzyme | | Able to be proved wrong |
| Microorganism | | Set of procedures scientists use their investigations includes four steps, observations and facts, hypotheses and predictions, testing, and evaluation and interpreting of results |
| Observation | | Fake science |
| Prediction | | What you can see, hear, smell, taste, or feel physically |
| Psuedoscience | | All of the chemical reactions that sustain life |
| Quackery | | Educated speculation about what an outcome will be |
| Scientific Method | | Possible cause or mechanism that could explain observations and facts |
| Test | | The assignment of every species to a genus, family, order, class, phylum, and kingdom |
| Testability | | Large molecule made up of many atoms |
| Theory | | Reproduction that requires a single parent. occurs in single celled organisms |
