Final 1st Flashcards
Wave
a disturbance that transfers energy from one place to another without requiring matter to move the entire distance.
Medium
a substance through which a wave moves
Mechanical wave
a wave such as a sound or seismic wave that transfers kinetic energy through matter
Transverse wave
a wave in which the disturbance move at right angles to the direction of the wave
Longitudinal wave
a wave in which the disturbance moves in the same direction as the wave.
Crest
the highest point in a wave
Trough
the lowest point in a wave
Wavelength
the distance from one wave crest to the next wave crest
Frequency
the number of waves that pass a fixed point in a given period of time
Electromagnetic spectrum
the range of all electromagnetic frequencies
Transmission
the passage of waves through a medium
Absorption
the disappearance of wave into a medium. The energy transferred by a wave is converted into another form of energy.
Observation
the act of noting and recording an event, characteristic, or anything detected.
Investigation
the process of collecting evidence
Hypothesis

Conclusion

Experiment
a test, trial, or tentative procedure, an act or operation for the purpose of discovering something unknown.
Problem

Solution
the answer to a scientific problem or investigation
Biotic factor

Abiotic factors

Species
any living organism that is so similar that it can breed and produce offspring that can produce offspring.
Population
the number of a particular species living in a particular area.
Community
all of the different populations living in a particular area
Variable
the part of an experiment that may change or vary
Control
the thing in an experiment that does not change
Symbiosis
the interaction between two different species that live closely together
Commensalism
the interaction between two species in which one benefits and the other is not harmed
Mutualism
the interaction between two species where both benefit
Parasitism
the interaction between two species where one benefits and the other is harmed
Biome
the natural environment in which a living thing gets all that it needs to survive.
Producer
an organism that makes its own food and does not consume other plants or animals
Consumer
an organism that eats other living things to get energy, an organism that does not produce its own food.
