✔✔What instrument would help you precisely measure an angle? - ✔✔A Protractor
✔✔What is the mode? - ✔✔The number or numbers that occur most often in the data
set.
✔✔What is the mean? - ✔✔The average of the number set.
✔✔What is the Median? - ✔✔The middle number or the average of the 2 middle
numbers.
✔✔What is the range of a number set? - ✔✔Subtract the smallest from the largest
number in the set.
✔✔How many more faces does a cube have than a triangular pyramid? - ✔✔2
✔✔What are syllogisms? - ✔✔Deductive reasoning strategies composed of major
premise, minor premise, and a conclusion.
✔✔What is inductive reasoning - ✔✔Bases conclusions on specific examples and can
sometimes not be logically valid.
✔✔In the hydrologic cycle, which process transforms liquid to gas? - ✔✔Evaporation - a
physical change; it turns water into a gaseous state
✔✔In the hydrologic cycle, which process turns gas to liquid? - ✔✔Condensation.
✔✔In the hydrologic cycle, which process turns solid to gas? - ✔✔Sublimation (like
when dry ice "smokes")
, ✔✔In the hydrologic cycle, which process turns gas to liquid? - ✔✔precipitation
✔✔What is climate? - ✔✔The overall weather pattern over time in a certain region.
✔✔What does "biotic" mean? - ✔✔the living elements in a biome - plants, mammals,
insects
✔✔What does abiotic mean? - ✔✔non-living element in a biome - pond, rain, sunlight.
✔✔What is the purpose of the scientific method? - ✔✔To use observation to test
hypotheses and make predictions.
✔✔What is the scientific method based on? - ✔✔observation and the replication of
results; hypotheses are formed and tested, with the hope that a theory can be created
from the cycle of tested hypotheses.
✔✔According to Darwin's idea of natural selection... - ✔✔Populations pass down traits
that help them adapt to their environment.
✔✔19th century scientist George Mendel believed that... - ✔✔The emergence of one
trait will not affect the emergence of another.
✔✔How many planets in our solar system are known to have rings? - ✔✔4 - Jupiter,
Saturn, Uranus and Neptune
✔✔Give an example of the rain shadow effect: - ✔✔A town on the leeward side of the
mountain receives little annual rainfall.
Leeward side - ✔✔Side of the mountain protected from the wind.
✔✔What is the rain shadow effect? - ✔✔Mountains push moist air to higher altitudes
where it cools, and water vapor condenses to form rain or snow that only falls on the
windward side.
✔✔Can the gemstone sapphire be scratched by quartz? Why? - ✔✔No, because it is a
variety of corundum, which ranks a very high 9 on the Mohs scale of mineral hardness.
Quartz is a 7 on the scale.
✔✔Where is lignite on the Mohs scale of hardness? - ✔✔It is a very soft form of coal, so
it is low.
✔✔Where is talc on the Mohs scale of hardness? - ✔✔It is a 1; it can be scratched with
your fingernail.
