A student observes that an organism is green. A valid
conclusion that can be drawn from this observation is
that
the organism must be a plant
the organism cannot be single celled
the organism must be an animal
not enough information is given to determine whether the organism is a plant or an animal
A student is investigating the effect of different
factors on the growth of a certain type of bean plant
over 30 days. Which factor would not function as a
variable in this investigation?
type of bean plant
soil moisture content
amount of light
tempreture
A scientist would like to test the effect of heat on the
function of a certain enzyme. Which would not be an
appropriate first step?
doing research in a library
having discussions with other scientists
completing a data table of expected results
using what is already known about the enzyme
The analysis of data gathered during a particular
experiment is necessary in order to
formulate a hypothesis for that experiment
develop a research plan for that experiment
design a control for that experiment
draw a valid conclusion for the experiment
Why do scientists consider any hypothesis valuable?
A hypothesis requires no further investigation.
A hypothesis may lead to further investigation even if its disproved by the experiment
A hypothesis requires no further investigation if
it is proved by the experiment.
A hypothesis can be used to explain a conclusion
even if it is disproved by the experiment.
X, only
Y, only
Z, only
both X and Y
In a scientific investigation, after the question is
asked, the next step is to
formulate a hypothesis
identify needed equipment
design the experiment
collect the data
When a test tube of water containing an elodea plant
is placed near a bright light, the plant gives off gas
bubbles. When the light is placed at different
distances from the plant, the rate of bubbling is
affected. The experimental variable in this
demonstration is the
concentration of gas in the water
type of aquatic plant in the test tube
amount of water in the test tube
distance of the plant from the light
30%
55%
75%
95%
A student conducted an original, well-designed
experiment, carefully following proper scientific
procedure. In order for the conclusions to become
generally accepted, the experiment must
contain several experimental variables
be repeated to verify the reliability of the
data
support the original hypothesis
be conducted by a scientist
penicillin
erythromycin
streptomycin
chloramphenicol
To compare the growth of plants grown under
specific colors of light with that of plants grown
under natural conditions, four groups of bean plants
were grown under the light conditions indicated
below. All other factors were kept constant.
Group A – red light
Group B – green light
Group C – violet light
Group D – white light
In this investigation, which group of plants served as
the control?
A
B
C
D
An experiment was designed to determine if
chlorophyll is responsible for the growth of corn
seedlings toward light. In the experiment, equal
numbers of albino corn seedlings and green corn
seedlings were grown at a temperature of 24oC. All
other environmental conditions were the same for
both groups of seedlings. The results of the
experiment showed that both the albino seedlings and
the green seedlings bent toward light.

An experiment was designed to determine if
chlorophyll is responsible for the growth of corn
seedlings toward light. In the experiment, equal
numbers of albino corn seedlings and green corn
seedlings were grown at a temperature of 24oC. All
other environmental conditions were the same for
both groups of seedlings. The results of the
experiment showed that both the albino seedlings and
the green seedlings bent toward light.
Which hypothesis is being tested in this experiment?
Albino corn seedlings grow as fast as green
corn seedlings.
Chlorophyll is needed for corn seedlings to
grow toward light.
Differences in genotypes produce variations in
corn phenotypes.
Light is required for germination of corn.

Which is a variable in this experiment?
type of soil
type of corn seedlings
temperature
light
In an experiment, what should be the relationship
between the control group and the experimental
group?
They should be different in size.
They should resemble each other in at least two
respects.
They should not be similar in any respect.
They should be identical in all respects
except one.

A detailed laboratory procedure was performed and
showed that plants given a growth solution grew
faster than those not given the solution. When other
researchers conduct this study to test the accuracy of
the results, they should
give growth solution to both groups
make sure the conditions are identical to
those in the first study
give an increased amount of light to both
groups of plants
double the amount of growth solution given to
the first group
