C165- Integrated Physical Science: Unit
2: Scientific Inquiry
Iron ore consists mainly of iron atoms and oxygen atoms joined to each other to form several different
possible forms of iron oxide. Which branch of physical science MOST directly deals with developing ways
to remove the oxygen from iron oxide, thus leaving iron metal? Ans-earth science
Which field of physical science MOST directly explains how the motion of the continents over 100
million years led to mountains and volcanoes in some places above land, and deep ocean trenches in
other places beneath the ocean surface? Ans-Earth Science
Which type of scientific study is BEST suited for collecting data that will be used to analyze statistical
information about the kinds of meanders, or turns, in the path of rivers such as the one shown in the
photograph below?
Image of a rock arch formed by wind and rain. Ans-field study
Geckos, like the one shown here, are known for being able to walk on very smooth surfaces, even
upside-down. Tiny ridges on the gecko's feet allow it to stick to a smooth glass surface because of weak
forces between the atoms in the gecko's foot and the atoms in the glass.
Which two fields of physical science would be MOST relevant in investigating how a gecko sticks to
glass? Ans-physics & chemistry
A scientific procedure done in order to test a hypothesis is a(n) Ans-experiment
While on a hiking trip, several children become sick after drinking water from a well. Which of the
following is a hypothesis concerning this situation? Ans-Bacteria in the well may have caused the
sickness
A scientific theory is discarded Ans-A theory is discarded or modified if new data contradict it.
, In what sense was the ancient Ptolemaic system used to describe the motion of the planets a model?
Ans-It described the motion of the sun & planets along imaginary spheres.
The Ptolemaic system was based on an elaborate system that differed from the real motion of the
bodies involved, but could reproduce its main features.
When there is no conceivable way to prove a statement false, then the statement is Ans-untestable
Science can be defined as Ans-a body of knowledge that is subject to change as more evidence is
gathered
Which of these best describes how atomic theory developed? Ans-Many people at different times
contributed to the discovery of the atomic nature of matter and subatomic particles
Why is it useful for there to be an official size for each unit? Ans-to allow people in different locations to
compare measured values
Correct. People in diverse locations can communicate about the lengths of time intervals, the sizes and
masses of objects, and relay other measurements, and all agree on what the numbers mean because the
units used have precise official values.
Which of the following is closest to your height? Ans-2m
Which of these is not a derived SI unit Ans-kilogram
Kilogram is the SI base unit for mass
What is the SI base unit for mass Ans-kilograms
If each side of a square is decreased two times, the resulting area of the new square will
