Science Flashcards
Plates moving away from each other - dividing
Divergent
Plates moving side by side
Transform
Plates colliding/ converging / crashing
Convergent
Heat transfer from one thing to anothe (match to finger)
Conduction
Heat that is circulated - movement of fluid caused by heat
Convection
Person credited for the discovery of DNA
Friedrich Miescher
What part of our body benefits from vitamin D?
Bones
Acids that are needed by the body in order to function
Amino acids
Stimulates certain portions of the automatic nervous system
Caffeine
“Female” part of a flower
Pistil
Regulates sugar in the body - endocrine and digestive system

Organ
Organ system
Organism
Founder of modern genetics
Gregor Mendel
Closed environment cycle in nature
Terrarium
2 types of biomes
Water and land
Comes from plants through decomposition, waster (animals), and fungus
Nitrogen cycle
Process by which unrelated/distantly related organisms evolve similar body forms, coloration, organs and adaptation
Convergent evolution
Occurs when 2 different species share a common ancestor but have different characteristics from one another
Divergent evolution

Homeothermic
Amphibians require ______ to mantain body functions
Sunlight
Metal that is magnetic
Steel
Convergent radiant energy to thermal energy
Snakes and lizards
How do fossil fuels affect the Earth?
They release carbon dioxide
How heat moves from one place to another
Conduction
Convection
Radiation
Measures gravity
Spring scale
Measures air pressure and predicts changes in the weather
Barometer
Measures exact wind speeds
Anemometer
Earth´s trip around the sun EQUAL 1 year winter/summer solstice
Revolution
4 phases of the moon
New Moon
1st quarter

24 hours
Rotation
Time it takes for the moon to go through all 4 phases
28 days/1 month
During the day, during New Moon, the moon blockes the sun for a short time
Solar Eclipse
Always in between the Earth and the sun

(My very excited mom just served us nachos)
Gradual release - 7 days of the moon changing
Transitional phases
Accumulative of forces acted on an object (math problem)
Net force
During the night, during the full moon, blood moon (red)
Lunar Eclipse
Property of physical body and a measure of its resistance to acceleration when net force is applied
Mass
Terrestrial/rocky planets
Mercury
Venus
Earth
Mars
Easily separated.
Comprises 2 or 3 compounds that aren´t fused chemically
Mixture
Gas giants
Saturn
Jupiter
Neptune
Uranus
Cannot control /manipulate / alter variable but can rely on interpretation, observation, or interaction to conclude - age, race, ethnicity
Nonexperimental
How close different measurements are to one another - consistent
Precision
The variable can be controlled - light, temperature, sound
Experimental
Seed, germination, growth, reproduction, pollination, and seed spreading
Plant life cycle
Resistance to changes in motion
Object remains at rest or remains in motion unless acted upon
Inertia
3 laws of motion
Inertia
Acceleration
Action / Reaction
Taxonomic classification
Domain, kingdom, phylum, class, order, family, genus
(Dumb King Philip Came Over From Great Spain)
Physical properties
Hardness, luster, density
Amount of mass present in a given volume

Gold bar : high mass/small volume
Density
Contains 2 substances that are chemically mixed to form a new compund
Solution
Close doors to prevent energy from traveling
rubber, glass, oil, diamond, dry wood
Insulators
3 stage life cycle
