which of the following describes scientific inquiry? (1 point)
a statement that describes what scientists expect to happen in an experiment
facts, figures, and other evidence gathered through observation
the diverse ways in which scientists study the natural world
a well-tested explanation for a wide range of observations
For questions 2–4, use the following information.
Calvin and Michelle wanted to test the effects of different household cleansers on the growth of
mildew. They selected three identical bathroom tiles to use in their experiment. To one tile, they
applied Brand X cleanser. To another, they applied Brand Y cleanser. The third tile did not receive any
cleanser. They observed the growth of the mildew over a period of four days. Their results are shown
in the table below.
Growth of mildew
Date Brand X cleanser Brand Y cleanser No cleanser
Area (mm2) Area (mm2) Area (mm2)
05/18/11 0 0 0
05/19/11 0 0.25 0.50
05/20/11 0 1.0 1.25
05/21/11 0.20 2.75 3.0
2. Which of the following is a constant, or control variable, in this experiment? (1 point)
the results observed over four days
the brand of cleanser that worked best
the use of identical bathroom tiles
the brand of cleanser that didn’t work.
3. What is the independent, or manipulated, variable in this experiment? (1 point)
the tile with no cleanser
the growth of the mildew
the number of tiles used
the type of cleaner used
4. What is the dependent, or responding, variable in this experiment? (1 point)
the tile with no cleanser
the growth of the mildew
the number of tiles used
the type of cleanser used
5. Which statement best describes the benefit of having a universal system of measurement?
(1 point)
Scientists from different countries can more easily share and compare data from
experiments.
Scientists who speak different languages do not have to translate each other’s work into
their own languages.
Countries that did not have a system of measurement before the invention of the metric
system now have one.
Experiments that use the metric system are 50 percent more accurate than experiments
that don’t use the metric system.
7. Which of the following statements incorrectly describes a tool used by scientists? (1 point)
A compound light microscope enables a scientist to view objects too small for the unaided
eye to see.
A beaker is a type of glassware a scientist uses in the lab to record data.
A scale is used to measure weight.
A ruler is used to measure length.
8. Luis is an avid baseball player. For his science project, he decides to test which type of bat
is best for hitting home runs. Luis prefers to use an aluminum bat when he plays, so he
hypothesizes that he will hit more home runs using an aluminum bat than a wooden bat.
During batting practice, he tests his hypothesis. He hits a baseball with a wooden bat and
it lands near first base. He swings the aluminum bat with all his might and the ball sails
over the back fence. He concludes that the data supports his hypothesis.
Which of the following statements reveals Luis’ experimental bias?
He swings the aluminum bat with all his might.
He will hit more home runs using an aluminum bat than a wooden bat.
Luis is an avid baseball player.
