| conducts (conductor) | allows heat to travel through it |
| insulate (insulator) | does not let heat out; does not allow heat to travel through it |
| physical state or states of matter | solid, liquid or gas |
| friction | goes AGAINST or OPPOSITE of motion; causes motion to slow down and stop |
| canyons | formed by moving water; weathering and erosion (a hole in the ground) |
| delta | formed by moving water; erosion and deposition |
| complete circuit | electrical energy can flow |
| incomplete circuit | electrical energy can NOT flow ("in" means not) |
| interdependency | living depends on the nonliving to survive in its environment |
| organism | living things |
| evaporation | light water turns into water vapor (gas) when heat is added |
| condensation | water vapor turns into liquid water when heat is REMOVED |
| transpiration | water vapor is released from PLANTS |
| precipitation | water in the form of rain, snow, sleet or hail falls from clouds |
| sun | the source of all energy |
| teeth | an adaptation to an organism's food source (sharp teeth-meat eater; large flat teeth-plant eater) |
| physical properties of matter | characteristics of matter; how we describe matter, ex) physical appearance, physical state, magnetism, volume, conductor/insulator; density; solubility |
| solubility | does it dissolve |
| dissolving | when a substance evenly spreads out in a liquid; the substance loses the property of size and shape ex. salt dissolving in water |
| relative density | floating or sinking when compared to water |
| volume | the amount of space that a substance or object takes up |
| thermal energy | heat energy |
| mixture | 2 or more substances that are mixed together and KEEP all of their physical properties; can be easily separated |
| mass | the amount of matter in an object; measured in grams with a triple beam balance |
| spring scale | a science tool that measures FORCE in Newtons (N) |
| boiling point | 100 degrees Celcius; water changes from a liquid to a gas |
| Freezing point | 0 degrees Celcius; water changes from a liquid to a sold |
| Melting point | 0 degrees Celcius; water changes from a solid to a liquid |
| matter | anything that has mass AND takes up space |
| M.E.L.T.S. | forms of energy: mechanical, electrical, light, thermal, and sound |
| energy USED | energy you are STARTING with |
| energy produced | what energy changes into (energy changes forms) |
| refraction | light BENDS or changes direction and speed |
| reflection | light BOUNCES off an object ex. mirror; smooth, shiny surface, calm water, TV screen |
| prism | a tool that refracts (bends) light into its 7 colors |
| Roy G. Biv | red, orange, yellow, green, blue, indigo, violet; 7 colors of white light |
| series circuit | a complete circuit with only 1 loop; only one way for electrical energy to flow; if one light goes out, they ALL go out |
| parallel circuit | a complete circuit with 2 or more loops; if one light goes out, the others stay lit |
| U-shaped valley | formed by a glacier; weathering and erosion (hole in the ground) |
| sand dunes | formed by wind; erosion and deposition |
| weathering | the breaking of rock |
| erosion | the movement of rock |
| deposition | the placement of rock in a new location |
| slow changes to the land | Weathering, erosion and deposition (WED) |
| fast changes to the land | earthquakes, hurricanes, tornados, land slides, |
| landforms | the forms of the land; ex. valleys, plains, mountains, deltas, canyons, sand dunes |
| sedimentary rock | rock that is formed by layers of sediment; sediment is deposited, sediment is compacted, sediment is cemented together |
| compact (compaction) | pressure |
| cementation | when pieces of sediment are "stuck together" with minerals in the water |
| sediment | small pieces of rock |
| coal | is made from ferns in ancient swamps |
| oil | is made from microscopic sea organisms in ancient seas |
| natural gas | is made from microscopic sea organisms in ancient seas |
| order of the planets | Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune (the Mnemonic for remembering the order of the planets: My very educated mother just served us nachos) |
| interacts | to work or play together |
| switches | open or closes a circuit |
| open or incomplete circuit | there is a break in the circuit so electricity can NOT flow through it |
| closed or complete circuit | the circuit has NO breaks so electricity can flow through the circuit |
| biotic | living or once living parts of an ecosystem |
| abiotic | non living parts of an ecosystem; ex. water, air, soil, temperature, sun |
| day/night cycle | when the earth makes ONE complete rotation on its axis; 24 hours |
| renewable resources | resources that can be made again or will never run out; ex.) animals, plants, water, sunlight, wind |
| nonrenewable resources | resources that will NOT come back, they can not be made again; example: coal, oil and natural gas |
| petroleum | oil |
| solar | sun |
| nocturnal | night; example: owls hunt at night |
| poor conductor | insulator |
| good conductor | allows heat and electricity to flow through it |
| maintain | to keep |
| cantaloupe | a type of fruit |
| types of insulators | wood, plastic, rubber, |
| types of conductors | all metals |
| occurs | happens; participates |
| a method used to separate a solution | evaporation ex) to separate a salt water solution, boil off the water and you are left with salt |
| tools used to separate mixtures | filter and funnel, magnet, tweezers, sifter or screen |
| Can you use a filter and funnel to separate a solution? | NO!!! Since it is a solution, the salt lost the property of size and shape when it dissolved, so the salt will go straight through the filter paper. |
| decline | less of something; to go down in number |
| variable | the one thing that is being CHANGED in an experiment |
| retain | totr keep |
| process | the steps needed to do something |
| ingredients | substances contained in a recipe or an experiment |
| investigation | an experiment |
