Question: Which question requires a controlled experiment to answer?
Which type of rock contains the most calcium?
Which planet has the most moons?
Which elements are found in Earth's atmosphere?
Which fossils formed earliest in Earth's history? - CORRECT ANSWER✔✔Which type of rock
contains the most calcium?
Question: 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?
Hypothesis
Theory

Law
Prediction - CORRECT ANSWER✔✔Law
Question: 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?
Hypothesis
Theory
Law
Prediction - CORRECT ANSWER✔✔Theory
Question: 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?

Question: Which study involves both Earth science and physics?
Calculating how much energy is associated with a hurricane
Measuring the energy produced by a generator
Comparing the composition of crude oil from different regions
Monitoring changes in phosphorus levels of a lake - CORRECT ANSWER✔✔Calculating how
much energy is associated with a hurricane
Question: Which question could be answered with a controlled experiment?
