C165 Integrated Physical Science - Section 1
Test
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?
Chemistry
Which field of physical science deals MOST directly with which atoms join together to form
molecules?
Chemistry
Iron ore consists mainly of iron atoms and oxygen atoms joined to each other to form iron
oxide. Which branch of physical science MOST directly deals with determining the kinds of
rock formations likely to contain iron ore?
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?
Earth science
Satellites orbiting Earth scan the light reflected from below, and the data can then be
analyzed to get information about the objects that reflected the light. This technology is
called "remote sensing." For example, they can even distinguish between Astroturf in a
football field and real grass on the ground below, even though these look the same to the
human eye.
Which field of science would MOST directly devise ways to detect and analyze reflected
light obtained by remote sensing?
Physics
A scientist sets out to test his hypothesis that warmer sand temperatures during the
incubation of turtle eggs produce female hatchlings and cooler sand temperatures produce
males. The independent variable is
the temperature.
, The variable that a scientist changes in an experiment is called the
independent variable.
Which term BEST describes a research project in which scientists place microphones at the
bottom of the seafloor to study the sounds orca whales make?
A field study
The Hubble space telescope was launched into orbit to take far sharper images than
possible on Earth. It has since collected data that show some distant stars to have planets.
The scientific investigation involved is BEST described as
an observational study
Which field relies the MOST on laboratory studies?
Chemistry
Many species of fish contain a swim bladder within their body that is filled with gas and
helps the fish to control and maintain their depth below the water. Which fields of science
MOST directly explain the operation and evolution of the swim bladder of fish?
Physics and life science
A class carries out an experiment in which they allow the weight of the block with mass m2
to pull block m1 into motion, and then they measure the speed attained each time the
hanging mass reaches the ground. They repeat this for different masses m2. The
independent variable is
the mass m2.
Which topic dealt with by physics would be the MOST DIRECTLY important in life science?
How drag forces influence the motion of bacteria as they swim through water
When the electric eel needs electricity, its complex system of nerves simultaneously
activates thousands of electricity-producing cells. As each cell receives the signal, it
releases a tiny amount of the molecule called AChE. The study of the properties and
interactions of AChE would be in the realm of
chemistry.
Ocean tides are caused by the force of gravity mainly from the moon and secondarily from
the sun as Earth rotates on its axis. Which pair of physical sciences MOST directly deals
with the tides and what causes them?
Physics and Earth science
Geckos 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.
