Comparing the composition of crude oil from different regions
Monitoring changes in phosphorus levels of a lake - ✔Calculating how much energy is
associated with a hurricane
Which question could be answered with a controlled experiment?
Does ice melt faster in an empty glass or in a glass full of water?
Do all planets have the same shape of orbit around the sun?
What is the maximum distance between Earth and Jupiter?
What is the length of the longest river in North America? - ✔Does ice melt faster in an
empty glass or in a glass full of water?
Which topic would be appropriate for a controlled experiment?
Determining how fast different chemical pollutants dissolve in water
Comparing the elements present in different stars
Measuring how fast a river flows
, Predicting the path of a tornado - ✔Determining how fast different chemical pollutants
dissolve in water
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? - ✔Which type of rock contains the most
calcium?
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 - ✔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?
Hypothesis
Theory
Law
Prediction - ✔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?
Hypothesis
Theory
Law
Observation - ✔Hypothesis
