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
