|---|---|
| Control Group | The group that is not being tested |
| Experimental Group | The group that is being tested in the experiment |
| Independent Variable | The variable that is being manipulated or changed |
| Dependent Variable | The variable that is the outcome of test/experiment |
| States of Matter | Solid, Liquid, Gas, Plasma. |
| Solid to Liquid | Melting |
| Liquid to Solid | Freezing |
| Liquid to Gas | Vaporization & Evaporation |
| Gas to Liquid | Condensation |
| Solid to Gas | Sublimation |
| Physical Property | Observed without changing chemically . |
| Chemical Property | Observed without changing physically. |
| Compound | A pure substance of 2 or more elements combined |
| Mixture | A combination of two or more substance combined |
| Solution | A mixture in which one substance dissolves another |
| Solute | The substance being dissolved |
| Solvent | The substance that is dissolved into |
| Element | A pure substance made out of kind of atom |
| The Three Metal Groups | Metals, Non-Metals, Metalloids |
| Metals | Good productors of heat and electricity |
| Non-Metals | Poor productors of heat and electricity |
| Metalloids | Have properties of metals and non-metals |
| Atomic Number | Number of protons |
| Electrons | Number of protons |
| Neutrons | Mass - Protons |
| Force | A force is a push or pull that causes an object to move, stop, or change direction |
| Newton | Unit of Force |
| Balanced Forces | The force in each direction are equal |
| Unbalanced Forces | The more force in one direction then the other |
| Formula Force | Mass X Acceleration - Force |
| Speed | The distance traveled by and object divided by time |
| Formula Speed | Distance/Time |
| Velocity | The speed of an object in a direction |
| Formula Acceleration | Final V - Orginal V / Time |
| Formula Distance | Speed X Time |
| Formula Time | Distance/Speed |
| Newton 1st Law | Object at rest stays at rest/ Object in motion stays in motion |
| Inertia | The reson objects move or stay at rest |
| Newton 2nd Law | The acceleration of an object depends on the mass of it |
| Newton 3rd Law | The force exters and equal and opposite amount of force back |
| Constant | What needs to stay the same in the experiment |
| 3 Types of Rocks | Igneous, Metamorphic, Sedimentary |
| Igneous Rock | Formed from the cooling of molten rock or magma |
| Sedimentary Rock | Rocks that are broken into sediments and moved by erosion |
| Metamorphic Rock | Rocks formed from other rocks |
| Cycle Igneous | Cooling & Melting |
| Cycle Sedimentary | Weathering & Erosion |
| Cycle Metamorphic | Heat & Pressure |
| Minerals | naturally formed on earth |
| Hardness | A measure on how easily minerals can be scratched (Mohs Scale) |
| Luster | The way a mineral reflects light |
| Streak | The color of mineral in its powder form |
| Earths Three Layers | Crust, Mantle, Core |
| Oceanic Crust | Very dense |
| Continental Crust | Less dense |
| Two Core Layers | Inner Core, Upper Core |
| Contiental Drift | The theory that the all of the continents were once one big continent |
| Alfred Weigner | Person who came up with the Continental Drift theory |
| Pangea | The big supercontinent |
| Teconic Plates | This is what made the contients seperate from eachother |
| Volcano | A mountain that forms when molten rock is forced to Earth’s surface. |
| 2 Types of Eruptions | Non-explosive & Explosive |
