Terms in this set (20)
a problem solving technique used to investigate observations that can be made about living and non-living things; may include stating a problem, gathering information, forming and testing a hypothesis, analyzing data and drawing conclusions.
Any pieces of information acquired through observation or experimentation.
A proposed answer to a question
A variable that is kept constant during a controlled experiment.
The experimental factor that is manipulated; the variable whose effect is being studied.
The outcome factor; the variable that may change in response to manipulations of the independent variable.
Any natural resource (as wood or solar energy) that can be replenished naturally with the passage of time
a resource that cannot be reused or replaced easily (ex. gems, iron, copper, fossil fuels)
A way of measuring how much of an impact a person or community has on the earth. Someone who uses more natural resources will have a bigger footprint than someone who uses less.
A resource that is used in heating systems, in stoves, ovens, and some vehicles. It is the cleanest burning fossil fuel. It is nonrenewable.
An oily, dark-colored, flammable liquid found in the earth, consisting mainly of a mixture of various hydrocarbons. Gasoline, kerosene, fuel oil, paraffin, and lubricants are made from petroleum. Petroleum is non-renewable.
the most abundant fossil fuel, supplies most of the electricity consumed in the U.S. Coal is non-renewable.
Energy from the sun, solar energy is a renewable resource.
Energy derived from wind by means of windmills or wind turbines. Wind energy is a renewable resource.
Energy obtained from flowing water, a renewable energy source
ocean tides energy
currents created by the ocean that are converted to electricity, renewable resource
Energy derived from the heat in the interior of the earth, this is a non-renewable resource but is thought to be able to last a very long time.
Plant materials and animal waste used especially as a source of fuel. Biomass is considered a renewable resource
A nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy, uranium that fuels fission is considered a nonrenewable resource.
tragedy of the commons
Depletion or degradation of a potentially renewable resource to which people have free and unmanaged access. An example is the depletion of commercially desirable fish species in the open ocean beyond areas controlled by coastal countries.
