C165 INTEGRATED PHYSICAL
SCIENCES PRE-ASSESSMENT EXAM
QUESTIONS AND ANSWERS GRADED A+
2026
A mathematical model is used to predict the trajectory of a bullet fired from a gun.
Which discipline of physical science is used to develop this model? - ANS Physics
An environmental scientist monitors pollutants in a lake.
Which two disciplines of physical science does this scientist use?
Choose 2 answers - ANS 1. Chemistry
2. Earth science
Which study involves both Earth science and physics? - ANS Calculating how much energy is
associated with a hurricane
Which question could be answered with a controlled experiment? - ANS Does ice melt faster
in an empty glass or in a glass full of water?

, Which topic would be appropriate for a controlled experiment? - ANS Determining how fast
different chemical pollutants dissolve in water
Which question requires a controlled experiment to answer? - ANS Which elements are
found in Earth's atmosphere?
Sir Isaac Newton discovered that the force of gravity between two masses increases if the
masses increase, and decreases if the distance between the masses increases. No experiments
have ever contradicted this relationship.
Which type of scientific statement is this? - ANS Law
The well-accepted scientific explanation for many characteristics of Earth's crust states that the
crust is broken into several large plates. These plates move slowly over the mantle below
because of convection and other processes. Earthquakes and volcanoes are most common at
places where the plates interact. Evidence from physics, chemistry, and geology supports this
explanation.
Which type of scientific idea is this explanation an example of? - ANS Theory
A student proposes that sugar will dissolve faster in rubbing alcohol than in water. The student
reasons that sugar and rubbing alcohol both contain carbon so they will mix more easily.
Which type of scientific idea is the student's proposal an example of? - ANS Hypothesis
Why was the shrinking Earth idea replaced by the theory of plate tectonics? - ANS Plate
tectonics explained observations about Earth that the shrinking Earth idea could not explain.
Astronomers have long accepted that plate tectonics exists nowhere in our solar system except
on Earth. In 2011, a scientist analyzed 100 NASA-space-mission photographs of Valles Marineris
