Through which of the following practices have indigenous peoples
living in tropical regions of the world contributed most significantly
to modern science?
A. developing farming practices that improve the nutrient levels of
the soil
B. tracking the apparent annual movement of the sun and stars
C. identifying and using medicinal plants to treat illnesses and
injuries
D. desalinizing ocean water for use as fresh drinking water -
Correct Response : C. (Objective 0018) Indigenous peoples in the
tropical regions of the world have identified medicinal uses for
many local plants. An example of an important medicine originating
from the tropics is quinine, derived from cinchona bark, which is
used to treat malaria.
Which of the following contributions did Marie Curie make to the
development of scientific knowledge?
A. describing the structure of an atom
B. creating the periodic table of the elements
C. discovering the laws of inheritance
D. identifying new radioactive elements -

woman to be awarded a Nobel Prize. Curie was awarded Nobel
Prizes in both Physics and Chemistry for her work in the field of
radioactivity, a term she created. As one of the first scientists to
work in this field, she helped discover the radioactive elements
polonium and radium.
A fourth-grade teacher plans to have students complete a scientific
experiment to determine the role of different parts of the visible
light spectrum on the growth of bean plants. Students will grow the
plants, all of the same species, from seed in three different
containers. One container of bean plants will be grown under red
light, one container under green light, and one container under
blue light. The plants will all be treated in the same way (e.g.,
regular watering, same soil mix) except for the different colors of
light under which they will grow. Which of the following steps
would most improve the design of the overall experiment?
A. selecting different types of plants to grow under each type of
lighting to increase the relevance of the results
B. growing an additional container of plants in natural light to
establish a control
C. starting the plants as seedlings to avoid differences in the time
required for -
Correct Response : B. (Objective 0018) Chlorophyll and other
pigments in plants absorb energy from full-spectrum light to carry

out photosynthesis, a chemical process that allows plants to grow.
The experiment should include a container of bean plants grown
either in sunlight or under full-spectrum artificial light to ensure
that the conditions for growth are sufficient to produce healthy
bean plants and provide a baseline for comparing full-spectrum
lighting growth to single-spectrum lighting growth.
Fifth-grade students are submitting ideas to their teacher for their
science fair projects. Which of the following proposals is best suited
for a project utilizing scientific inquiry?
A. Why do black bears hibernate in the winter?
B. Which brand of crackers do fifth graders prefer?
C. Why does exercise increase your heart rate?
D. Which plant food works best on bean seedlings? -
Correct Response : D. (Objective 0018) Scientific investigations must
allow for a controlled and manipulated variable. A scientific
investigation can be designed to test which type of plant food
works best on bean seedlings. A student could obtain seedlings of
the same species and height; keep the amount of food, sunlight,
and water constant; and set up an experiment in which one or
more types of plant food are compared to a control.
