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?
5.
Which topic would be appropriate for a controlled experiment?
YOUR CORRECT
ANSWER ANSWER
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
6.
,Which question requires a controlled experiment to answer?
YOUR CORRECT
ANSWER 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?
7.
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?
YOUR CORRECT
ANSWER ANSWER
Hypothesis
Theory
Law
Inference
8.
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?
YOUR CORRECT
ANSWER ANSWER
Hypothesis
, YOUR CORRECT
ANSWER ANSWER
Theory
Law
Prediction
9.
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?
YOUR CORRECT
ANSWER ANSWER
Hypothesis
Theory
Law
Observation
10.
Why was the shrinking Earth idea replaced by the theory of plate tectonics?
YOUR CORRECT
ANSWER ANSWER
Plate tectonics was a new theory, which made it more reliable.
Plate tectonics explained observations about Earth that the shrinking Earth idea
could not explain.
Geologists voted on which theory to accept, and chose plate tectonics.
Many well-known geologists were involved in proposing plate tectonics.
