FINALS Flashcards
A disturbance that transfers energy from one place to another without requiring matter to move the entire distance
Wave
A substance through which a wave moves
Medium
A wave such as a sound or seismic wave that transfers kinetic energy through matter
Mechanical wave
A wave in which the disturbance move at right angles to the direction of the wave
Transverse wave
a wave in which the disturbance moves in the same direction as the wave
Longitudinal wave
The highest point of a wave
Crest
The lowest point of a wave
Trough
The distance for one wave crest to the next wave crest
Wave length
The number of waves that pass a fixed point in a given period of time
Frequency
The range of all electromagnetic frequencies
Electromagnetic spectrum
The passage of waves through a medium
Transmission
the disappearance of wave into a medium. The energy transferred by a wave is converted into another form of energy.
Absorption
The act of noting and recording an event, characteristic, or anything detected
Observation
The process of collecting data
Investigation
a tentative explanation for an observation or phenomenon, an if then statement
Hypothesis
the end of a scientific investigation, how it turns out
Conclusion
a test, trial, or tentative procedure, an act or operation for the purpose of discovering something unknown.
Experiment
What you’re trying to solve in a scientific investigation
Problem
The answer to an scientific problem or investigation
Solution
anything that was alive or was once alive
Biotic factor
The nonliving parts of an ecosystem
Abiotic factors
any living organism that is so similar that it can breed and produce offspring that can produce offspring.
Species
the number of a particular species living in a particular area
Population
the part of an experiment that may change or vary
Variable
The thing in an experiment that does not change
Control
the interaction between two different species that live closely together
Symbiosis
the interaction between two species in which one benefits and the other is not harmed
Commensalism
the interaction between two species where both benefit
Mutualism
the interaction between two species where one benefits and the other is harmed
Parasitism
the natural environment in which a living thing gets all that it needs to survive.
Biome
an organism that makes its own food and does not consume other plants or animals
Producer
an organism that eats other living things to get energy, an organism that does not produce its own food.
Consumer
