A.
dependent variable
B.
experimental variable
C.
independent variable
D.
controlled variable
Answer Explanation
Q #2: A group of students perform an experiment to test terminal velocity, which is the greatest speed obtained by a falling object. The students dropped different numbers of coffee filters and measured the resulting terminal velocity. Which of the following conclusions is supported by the data in the following table?
A.
Heavier objects take more time to reach terminal velocity.
B.
Heavier objects fall faster than lighter objects.
C.
Terminal velocity is when the force of gravity is equal to air resistance.
D.
The greater the number of filters, the smaller the terminal velocity.
Answer Explanation
Looking at the given table, increasing number of filters increases the mass. It is noted that terminal velocity increases with increasing mass. Thus, we can conclude that heavier objects (large masses) fall faster that lighter ones.
Q #3: Which of the following reasons explains why it is important for new scientific findings to be published?
A.
Publishing findings will help scientists become more biased
B.
Scientists will get paid if their findings are published
C.
Other scientists can validate or disprove the findings
D.
This prevents other scientists from performing similar tests.
Answer Explanation
Learning is a continuous process and publishing new findings help discover new and unknown discoveries. Publishing the results of experiments enables the scientific community the evaluate the finding themselves and help them repeat the experiment or build on them to verify or disapprove results.
