Nature of Science
a limited representation of something that can help us understand its structure or how it works
model
to clear trees from an area
Deforestation
the star at the center of our solar system that supplies heat and light to Earth; (Its enormous gravity keeps the solar system in orbit.)
sun
a push or pull that causes an object to move, stop, or change direction
force
an organism that consumes dead or decayed nonliving biomass without need for internal digestion (fungi: mushroom, mold)
Decomposer
the loss of soil as it is carried off by wind or water
Erosion
an animal of a large group distinguished by the possession of a backbone or spinal column, including mammals, birds, reptiles, amphibians, and fishes.
vertebrate
a natural satellite that orbits a planet
moon
a force that resists the motion of two surfaces sliding across one another
friction
consumers that eat only plants
Herbivore
a resource that can be replenished as fast as it is used (oxygen, water, solar, biomass)
Renewable resource
formed from deposits of pre-existing rocks or pieces of once-living organism that accumulate on the Earth's surface
Sedimentary rock
the Sun and all of the objects that move around it
Solar System
anything that has mass and takes up space
Matter
the process where plants use sunlight, water, and carbon dioxide to produce sugar and release oxygen
Photosynthesis
a resource that takes longer than our lifetime to replenish such as fossil fuels (oil also known as petroleum, coal, and gas)
Nonrenewable resource
the conversion of a vapor or gas to a liquid
condensation
a complete spin on an axis
rotation
a force that is not canceled out by another force and causes the motion of an object
unbalanced forces
any living thing
Organism
change from one form to another
Convert
an organism that can make its own food using energy from an external source
producer
a complete turn or orbit around a center
revolution
property that does not change the chemical composition of an object, including mass, weight, hardness, physical state, density, solubility, or conductivity
Physical property
carries out most of the digestive process, absorbing almost all of the nutrients you get from foods into your bloodstream
small intestines
