Flashcards in Final Deck (34):
1

Wave

a disturbance that transfers energy from one place to another without requiring matter to move the entire distance.

2

medium

Medium – a substance through which a wave moves

3

Mechanical Wave

a wave such as a sound or seismic wave that transfers kinetic energy through matter

4

Transverse Wave

a wave in which the disturbance move at right angles to the direction of the wave

5

Longitudinal Wave

a wave in which the disturbance moves in the same direction as the wave.

6

Crest

the highest point in a wave

7

Trough

the lowest point in a wave

8

Wavelength

the distance from one wave crest to the next wave crest

9

Frequency

the number of waves that pass a fixed point in a given period of time

10

Electromagnetic Spectrum

the range of all electromagnetic frequencies

11

Transmission

the passage of waves through a medium

12

Absorption

the disappearance of wave into a medium. The energy transferred by a wave is converted into another form of energy.

13

Observation

the act of noting and recording an event, characteristic, or anything detected.

14

Investigation

the process of collecting evidence

15

Hypothesis

a tentative explanation for an observation or phenomenon, an if then statement

16

17

Experiment

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

18

Problem

what you’re are trying to solve in a scientific investigation

19

Solution

the answer to a scientific problem or investigation

20

Biotic Factors

anything that was alive or was once alive

21

Abiotic Factors

nonliving parts of an ecosystem

22

Species

any living organism that is so similar that it can breed and produce offspring that can produce offspring

23

Population

the number of a particular species living in a particular area.

24

Community

all of the different populations living in a particular area

25

Variable

the part of an experiment that may change or vary

26

Control

the thing in an experiment that does not change

27

Symbiosis

the interaction between two different species that live closely together

28

Commensalism

the interaction between two species in which one benefits and the other is not harmed

29

Mutualism

the interaction between two species where both benefit

30

Parasitism

the interaction between two species where one benefits and the other is harmed

31

Biome

the natural environment in which a living thing gets all that it needs to survive.

32

Producer

an organism that makes its own food and does not consume other plants or animals

33

Consumer

an organism that eats other living things to get energy, an organism that does not produce its own food.

34

Santa's Reindeer

Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donder, and Blitzen
