| Tool used to hold small amounts of liquids and mix chemicals in. | Test tube |
| Using observations or past knowledge to create a reasoned opinion on a topic or scene. | Inference |
| Positively charged part of the atom; remains in the nucleus. | Proton |
| Identity is shaped by the number of protons. A substance made up of only one type of atom. | Element |
| Charge-less parts of the atom; remains in the nucleus. | Neutron |
| Atoms of the same element with different numbers of neutrons. Caused by losing or gaining neutrons. | Isotope |

| Negatively charged atom. | Anion |
| Number which we use to organize elements on the periodic table. Also signifies the number of protons and electrons in an element. | Atomic Number |
| Number which states how heavy the atoms are. Is an average; not all types of the same element weigh the same. | Atomic Mass |
| Element that is malleable, ductile, a good conductor, and shiny. | Metal |
| Element that is not malleable, ductile, a good conductor, or shiny. | Nonmetal |
| Element that has the properties of both metals and nonmetals. | Metalloid |
| Columns on the periodic table. | Groups |
| Rows on the periodic table. | Periods |
| Metals in groups 3-12. | Transition Elements |
| Elements in groups 1-2 and 13-18. | Representative Elements |
| Bond formed when electrons move from one atom to another. Occurs between metals and nonmetals. | Ionic Bonds |
| Bond formed when two or more atoms share electrons. Occurs between nonmetals. | Covalent Bonds |
| Bond formed when a large amount of metal atoms share valence electrons. Occurs between metals. | Metallic Bonds |
| Law that states matter cannot be created or destroyed. | Law of Conservation of Matter |
| Molecule that consists of only one type of element. | Element Molecule |
| Molecule that consists of more than one type of element. | Compound Molecule |
| Substances that go through a change in reaction. | Reactants |
| Substances that result from change in reaction. | Products |
| Way of describing chemical reaction. | Chemical Equation |
| Shorthand way of writing atoms, molecules, and equations. | Chemical Formula (ex: H, H2, H2O2 -> H2O + O2) |
| Number that represents how many molecules there are. | Coefficient (ex: ->3H2O2) |
| Number that represents the number of atoms in a molecule. | Subscript (ex: 2H3<-) |
| When elements are combined to produce a compound. | Synthesis (ex: H20 + O2 -> H2O2) |
| When a compound breaks down into simpler parts. | Decomposition (ex: H2O2 -> H2O + O2) |
| Reaction where an uncombined element replaces another. | Single Replacement (ex: H + NaCl -> Na + HCl) |
| Reaction where parts of two compounds switch to form two new compounds. | Double Replacement (ex: H2O + NaCl -> H2Cl + NaO) |
| Properties that can be observed without changing the substance. | Physical Properties |
| Properties that describe the potential of substances to undergo chemical changes. | Chemical Properties |
| Change where the chemical structure of a substance is not altered. | Physical Change |
| Change where the chemical structure of a substance is altered. | Chemical Change |
| Push or pull. | Force |
| Force that opposes the movement of an object. | Friction |
| Strong push that quickly moves an object. | Thrust |
| When all forces acting on an object are equal. | Balanced Forces |
| A change in the velocity of an object. | Acceleration |
| Way an object is moving. | Direction |
| An object in motion will remain in motion with the same speed and direction unless acted on by an unbalanced force. An object at rest will remain at rest unless acted on by an unbalanced force. | Newton's First Law of Motion |
| The more mass an object has, the more force is needed to accelerate the object. | Newton's Second Law of Motion |
| With every action, there is an equal and opposite reaction. | Newton's Third Law of Motion |
| How fast an object is moving. | Speed |
| When forces acting on an object are not equal. | Unbalanced Forces |
| Speed and direction of an object. | Velocity |
| D/T | Find Speed |
| SxT | Find Distance |
| D/S | Find Time |
