The path an object takes around another object.
The large gas planets. Jupiter, Saturn, Neptune and Uranus.
A large ROUND body that ORBITS a star that has cleared most of its orbit of DEBRIS.

To turn on an axis. ex. The earth spins on its axis, resulting in day and night.
A body that revolves in orbit around another body. ex. the earth is a natural satellite of the Sun.

Finding similarities or differences between groups - no control group
Explain the results of the experiment and make inferences about what you think happened.
The group that is not changed in an experiment, used for comparison to the experimental group. The IV is not changed.
Variables in an experiment that are kept the same so they do not affect the results.
Table that organizes data collected during an experiment.
The variable being measured in an experiment, called the DV.
Collecting data by observing - no IV, DV, or hypothesis.
The group where one variable is changed on purpose. The IV is changed.
An investigation that includes all the parts of the scientific method; such as the IV, DV, hypothesis, constants, and controls
Visual representation of data that can show trends or comparisons.
Educated prediction; what you think will happen during an experiment.
The variable in an experiment that is manipulated or changed by the scientist, called the IV.
A guess. To assume something is true, usually based on reasoning or previous experience.
A fact. Act or power of noticing something by using one or more of your senses.
A well-defined question answered through performing an experiment. Written: How does the __IV__ affect the __DV__?
Assigned to a number to express the method of measurement used (ex. cm)
A component of the experiment that is changed, measured or kept constant in an experiment.
non-living factors of an ecosystem
reproduction that does not require a male and female, like splitting or budding. Results in identical offspring.
an organism capable of making its own food, using light or chemical energy. A producer.
constitute a large group of prokaryotic microorganisms that are unicellular, asexual and usually heterotrophic. This includes archaeabacteria and eubacteria.
living factors of an ecosystem
regulates not only what enters the cell, but also how much of any given substance comes in.
tough, flexible but sometimes fairly rigid layer that surrounds some types of cells, like plants, bacteria and fungi.
groups of different kinds of organisms that interact in an area in depend of each other.
the gel-like substance that fills up the cell
broadest or largest group of organisms in biological classification.
area where communities of organisms interact with each other and the abiotic factors in an environment.
cells that have a membrane bound nucleus and membrane bound organelles
an organism not capable of making its own food. A consumer.
organisms from a domain are classified into a more specific group.
organism made of more than one cell
an organelle that serves as the information and administrative center of the cell; found only in eukaryotes.
group of the same kind of organism that interacts and can produce offspring
cells that do not have a membrane bound nucleus or membrane bound organelles
organism made of only one cell
reproduction that requires a male and female. Results in a variety of offspring.
Study of classification and naming organisms.
Equal forces acting on an object in opposite directions. All forces acting on an object are balanced; so there is no change in motion or speed.
Compares the amount of output force by a machine to the required input force.
A push or pull.
The force of attraction between two objects.
Simple machine with a flat surface that slopes.
The initial force you exert on a machine.
The SI unit for energy or work. Pronounced "jewel".
Object being moved during work or by a machine.
Device that makes work seem easier.
A change in position.
The total amount of force acting on an object.
The SI unit of force.
The force exerted by a machine.
Machine that has a wheel with a rope, cable or chain around it.
s = d / t
The formula for calculating speed.
Speed = distance / time
Forces on an object that are unbalanced and result in the movement of the object
Amount of energy needed to move an object some distance. Force and motion must be in the same direction. ex. lifting a box
W = F X d
The formula for finding work.
Work = Force distance
cooling and hardening
processes that change magma or lava into igneous rock.
compaction and cementation
the processed by which sediments are pressed together, crystallize and glue particles of sediment together into sedimentary rock.
Process by which, in a fluid being heated, the warmer part of the mass will rise and the cooler portions will sink.
The movement of a fluid, caused by differences in temperature that transfers thermal energy from one part of the fluid to another and forms a current. ex. in the upper mantle
convergent plate boundary
Plate boundary where two plates move toward each other.
divergent plate boundary
Plate boundary where two plates move away from each other.
The movement of rock and sediment from one place to another by wind, water, or ice.
A break or crack in the Earth's lithosphere along which rocks move.
heat and pressure
The two processes that occur in the upper mantle that change rocks into metamorphic rock, without melting the rock completely.
A rock type formed from the cooling and hardening of magma or lava. Ex. granite, gabbro, basalt, obsidian
Features that make up the earth's surface. ex. Valleys, mountains, plains, trenches, mid-ocean ridges, canyons
Rock changed by heat and pressure to form another rock. Ex. marble, schist, gneiss, slate
A naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition. ex. quartz, garnet, graphite.
The theory that pieces of Earth's lithosphere are in constant motion, driven by convection currents in the mantle. Earth's plates meet at different types of boundaries, including convergent, divergent, and transform.
A series of processes on the surface and inside Earth that slowly changes rocks from one kind to another. metamorphic> Igneous> sedimentary >and so on
Particles created by the erosion and weathering of rock. Examples: sand, soil, gravel
Rock formed from the cementation and compaction of sediment. Examples: sandstone, limestone, shale, conglomerate
transform plate boundary
Plate boundary where two plates move past each other in opposite directions.
The breaking down of rock at or near Earth's surface. Weathering can be mechanical or physical. ex. wind, water, ice, animals and chemicals can break down rock
triple beam balance
tool used to measure mass
tool used to measure liquid volume; also used to measure the solid volume of an irregular object
ruler or meter stick
used to measure length and regular volume of solid objects
The measuring system based on the meter, liter and gram as the base units of length, volume and mass.
Pictures that warn about hazards: chemical, heat, electricity, or procedural. Ex. Clothing Protection Safety; Eye Safety, Chemical Safety, and Sharp Object Safety
A dense sphere of solid iron and nickel at the center of Earth
A layer of molten iron and nickel that surrounds the inner core of Earth
Earth's thickest layer, just below the crust, made of hot rock that has plasticity.
Earth's outermost layer.
The solid, plastic layer of the mantle beneath the lithosphere; made of mantle rock that flows very slowly, which allows tectonic plates to move on top of it.
