PRAXIS Elementary Education: Science Practice
Questions Already Passed
Earth's Layers
1- Crust: very thin, moves ontop
2- Upper Mantle:
3- Lower Mantle: ^ largest layer of Earth
4- Outer Core: so hot, metals are in liquid state/ nickel & iron
5- Inner Core: metals squeeze together like a solid bc pressure is so great- solid metals
Planets
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
inner four= terrestrial planets- rocky surfaces
outer four= Jovian planets- much larger, gaseous
Igneous rock
forms from solidified magma (granite)
Sedimentary rock
consolidated sediment, debris produced from weathering erosion (coal, limestone, gypsum)
Metamorphic rock
crystalized rock that has been exposed to high temperatures or pressure (slate, marble)
Biosphere
portion of Earth where living things live and includes other spheres
Lithosphere
rock, ground, earth
hydrosphere
, water
Atmosphere
air
Newton's first law of motion
a body in motion remains in motion unles acted upon by another force
newton's second law
acceleration is produced when a force acts on a mass. the greater the mass, the greater the
amount of force f=ma
Newton's third law
for every action, there is an equal and opposite reaction
Lunar Eclipse
Occurs when the moon moves into Earth's shadows and seems to disappear. earth is between
the moon and sun. Moon is blocked by earth's shadow
solar eclipse
sun--moon--earth
The moon casts a shadow upon the earth
Louis pasteur
discovered pasteurization, vaccines, and founded the science germ theory
francis Crick and James Watson
discovered the structures of DNA molecule
What are the categories for classification of living things
(Domain), Kingdom, phylum, class, order, family, genus, species
