INC1-Natural Science
What must be true about a scientific hypothesis? - ANSHypotheses must be falsifiable.
What is important for the formation of scientific hypothesis? - ANSCreativity and cooperation.
What correctly describes a theory? - ANSA group of well tested hypotheses that provide
evidence to support explanations for scientific phenomena.
Statement that accurately describes the purpose of the scientific method? - ANSTo provide a
systematic way for obtaining evidence to support or refute a hypothesis.
Statement that describes a scientific hypothesis? - ANSIt is a postulate that must be testable.
What is the benefit of using a systems approach when studying biology? - ANSA system
approach focuses on how components parts interact and can then predict how a change in one
component affects the whole system.
What is one of the following topics that is included in a study of physics? - ANSmotion, sound,
energy, atoms, and forces.
How does a study of science differ from a study of religion? - ANSReligion is based on faith,
beliefs, and spirituality whereas science depends on evidence generated from the experimental
scientific method.
What are units used to measure electricity? - ANSOhms, millivolts, amperes
What is the advantage of using a lever to lift a boulder? - ANSThe lever allows a smaller input
force to be exerted over a longer distance to make it easier to move the boulder.
How can creativity be helpful to scientist? - ANSIt helps in generating new ideas and new
hypotheses to test.
Which of the following definitions correctly describes a fundamental scientific term? - ANSA fact
is something that has been observed or experienced by many observers and agreed to be true.
Which of the following are scientific methodologies used to understand scientific phenomena? -
ANSField studies, experimentation, building models.
A student working on a controlled experiment desires to test the effect of water pH on tomato
plant size. Which of the following factors should be controlled? - ANSamount of soil, sun
exposure, amount of water.
, Which of the following studies follows a systems approach for biology? - ANSAnalyzing how the
concentration of ions in cardiac cells affects the electrical impulse in the heart.
Which of these would be an example of a systems approach to studying a forest ecosystem? -
ANSStudying how insects in the forest help pollinate the plants.
Which topics are studied in the Earth science category of the Natural Sciences? - ANSPlate
tectonics, acid rain, minerals.
What is the purpose of science? - ANSTo explain the causes of natural phenomenon.
Which of the following would be measured using micrometers? - ANSplant cell nuclei length and
mitochondria width.
Which of the following statement correctly describes the mechanical advantage of simple
machines? - ANSA turn of an axle to move a wheel provides a mechanical advantage by
decreasing the input force while increasing the distance.
Which is the best example of the law of conservation of energy? - ANSIf a pendulum is one
meter off the ground at one end of its swing, it can never be more than one meter off the ground
on the opposite swing.
Which of the following statements correctly describes Earth's magnetic field? - ANSIt deflects
charged particles coming from outer space.
Which of the following correctly describes the role of gravity in the formation of the solar
system? - ANSGravitation attraction caused matter in a nebula to condense ultimately forming
the Sun and planets.
Which of the following correctly describes the role of gravity in the Earth-moon system? -
ANSEarth's gravity causes the moon to elongate, changing its shape.
How does the law of universal gravitation differ from Coulomb's law of electrical forces? -
ANSGravitational force depends on mass whereas electrical force depends on the charge of
particles.
Which of the following actions would increase both the gravitational force and the electrical
force? - ANShalf the distance
Which type of energy is stored within sugar molecules? - ANSChemical potential energy.
Which of the following correctly describes the difference between electrical potential energy and
electrical kinetic energy? - ANSElectrical potential energy is energy due to the position of
