Calculating how much energy is associated with a hurricane
Which question could be answered with a controlled
experiment?
,WGU C165
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? - correct
answer 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 - correct answer 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?
, WGU C165
Which fossils formed earliest in Earth's history? - correct answer
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 - correct answer 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.
