Answer: Calculating howmuch energy is associated with a hurricane
4. Which question could be answered with a controlled experiment?
Answer: Does icemelt faster in an empty glass or in a glass full of water?
5. Which topic would be appropriate for a controlled experiment?
Answer: Determininghow fast different chemical pollutants dissolve in water
6. Which question requires a controlled experiment to answer?

7. Sir Isaac Newton discovered that the force of gravity between two massesincreases 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?
Answer: Law
8. The well-accepted scientific explanation for many characteristics of Earth'scrust states that
the crust is broken into several large plates. These plates move slowly over the mantle below
because of convection and other process-es. Earthquakes and volcanoes are most common at
places where the platesinteract. Evidence from physics, chemistry, and geology supports this
explanation.Which type ofscientific idea isthis explanation an example of?
Answer: Theory
9. A student proposes that sugar will dissolve faster in rubbing alcohol thanin 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?
Answer: Hypothesis
10. Why was the shrinking Earth idea replaced by the theory of plate tectonics?
Answer: Plate tectonics explained observations about Earth that the shrinking Earth idea
could not explain.
