6th Grade Science Final

Question 1

Condensation

Answer 1

change of a vapor or gas to a liquid

Question 2

conduction

Answer 2

energy is transferred from particle to particle by direct contact

Question 3

conductor

Answer 3

material that allows thermal energy transfer
Ex: copper, steel, sea water

Question 4

convection

Answer 4

the transferring of energy in liquids and gasses by particles moving in currents

Question 5

insulator

Answer 5

material that prevents thermal energy transfer
Ex: , wood, glass, rubber

Question 6

kinetic energy

Answer 6

energy of motion

Question 7

potential energy

Answer 7

stored energy

Question 8

radiation

Answer 8

energy is transferred in waves and doesn’t need particles to move along

Question 9

thermal energy

Answer 9

TOTAL amount of kinetic energy of ALL the particles in a system

Question 10

thermal energy transfer

Answer 10

movement of thermal energy from a hotter area to a cooler area

Question 11

cells

Answer 11

the smallest unit that can live on its own and that makes up all living organisms and the tissues
of the body

Question 12

cell membrane

Answer 12

thin layer that surrounds both plant and animal cells, allows some substances to
pass into and out of the cell while blocking others, which means it is
semi-permeable

Question 13

chloroplast

Answer 13

organelle where photosynthesis takes place, gets its green color from chlorophyll , only
found in plants

Question 14

cytoplasm

Answer 14

jellylike substance that fills the cell, where the organelles are located

Question 15

mitochondria

Answer 15

use oxygen and sugar (glucose) to provide energy for the cell (the mighty
mitochondria)

Question 16

nucleus

Answer 16

controls what goes on in the cell, contains the cell’s genetic material (DNA)

Question 17

organelles

Answer 17

structures found within cells

Question 18

sensory neurons

Answer 18

nerve cells that take in information from the outside world and send it to the brain

Question 19

arteries

Answer 19

vessels that carry blood away from the heart

Question 20

blood cells

Answer 20

Carries food and oxygen to other cells

Question 21

cerebellum

Answer 21

the part of the brain that controls movement/motion, balance, and ability to learn new
things

Question 22

cerebrum

Answer 22

largest part of the brain that controls the senses (seeing, hearing, tasting, touching,
smelling), imagination and thoughts

Question 23

digestive system

Answer 23

breaks down large food molecules into tiny food molecules that can move through
the intestine walls, into the blood, and then into each cell

Question 24

involuntary muscle movement

Answer 24

move things a person does not normally control ex. muscles that
move food through your intestine, and heart

Question 25

medulla

Answer 25

the part of the brain that controls involuntary actions, like breathing, digestion, and heartbeat

Question 26

nervous system

Answer 26

made up of the brain, spinal cord, and a network of nerves

Question 27

order of the body system

Answer 27

cell, tissue, organ, body system

Question 28

allele

Answer 28

a variation of a gene; some genes have 2 variations while others,like eye color, have multiple variations

Question 29

dominant

Answer 29

an allele that requires only one copy to be expressed

Question 30

asexual reproduction

Answer 30

requires only one organism and results in offspring that are genetically identical (a clone) to the parent

Question 31

genotype

Answer 31

an organism’s allele combinations (Tt, TT, tt)

Question 32

heterozygous

Answer 32

when you have both a dominant allele and a recessive allele for a trait (Tt).

Question 33

homozygous

Answer 33

when you have the same two alleles for a trait, either two dominant (TT) or two recessive (tt)

Question 34

phenotype

Answer 34

the physical appearance of an organism

Question 35

recessive

Answer 35

an allele that requires two copies to be expressed

Question 36

sexual reproduction

Answer 36

offspring receive genetic information from two parents (in humans 23 chromosomes from each for a total of 46) so they are not genetically identical to either parent

Question 37

climate

Answer 37

average atmospheric conditions in a general region over a long period of time (records kept in 30 year increments), what we expect

Question 38

climate change

Answer 38

a shift in worldwide climate patterns, including warming temperatures, increasing/decreasing precipitation totals, and more frequent extreme weather events, like hurricanes

Question 39

fossil fuel

Answer 39

a substance formed from ancient organic material that is used to generate energy, such as coal, oil, and natural gas

Question 40

greenhouse gasses

Answer 40

the substances in Earth’s atmosphere that trap heat including carbon dioxide, methane, nitrous oxide, fluorinated gasses, water vapor

Question 41

greenhouse effect

Answer 41

the Earth’s atmosphere trapping heat from the sun which keeps Earth just the right temperature to support life

Question 42

solar radiation

Answer 42

energy from the sun

Question 43

weather

Answer 43

atmospheric conditions on a specific day in a specific area; what we see day to day

Question 44

observation

Answer 44

something that can be detected or measured by the senses

Answer 46

- information that is gathered
