Which of the following statements defines a “theory”?
It can be tested and even falsified after numerous experimental
results.
Which of the following statements best describes a valid hypothesis?
Combining data from past experiments and using it to investigate a
particular topic in consideration
What is considered research within the scientific method?
Small sample size and limited experimental trials
Which of the following could cause errors in a scientific experiment?
,Observation, hypothesis, experiment, evaluation, conclusion
State the correct order of a scientific process.
Good observation
A researcher came up with a hypothesis about the behavior of reptiles
in the rainforest. Which step would be prior to stating the hypothesis?
By publishing in scientific journals
After the completion of a particular experiment, the findings have to
be shared with the scientific community. How is this typically done?
Universal law
The concept of gravity put forth by Sir Isaac Newton is an example of:
An iterative process
A researcher has concluded his experiment and has shared the results
with the scientific community. One additional step is included in the
scientific method where feedback is accepted by the researcher. What
is this step called?
Variable
A particular factor is constantly changed in an experimental study.
What is such a factor called?
Placebo
A clinical researcher administered a pill with no therapeutic value to his
subject. Which of the following best describes this treatment?
, It is a controlled experiment.
A lab student conducts a study on 10 different plants and their time of
exposure to light energy. What would you infer from this setup?
Deductive reasoning
Which of the following steps is used by the scientists to understand the
hypothesis?
Non-experimental hypothesis testing
A hypothesis which cannot be tested through experiments for various
ethical and practical reasons can be tested using:
You compare the experimental results with the predicted results
of the test.
Which of the following statements describe a conclusion?
Peer-review of manuscripts
A detailed process is carried out in order to examine a scientific paper
for the originality, significance, and logical reasoning of the obtained
data. Which of the following describes this process?
Double-blind
A group of scientists organized a clinical trial wherein no
information about the researcher and the subject was revealed
to each other.
Which of the following describes this particular study?
, Conclusion
A scientist recreates an experiment to check its reliability across
varying times and places. What would be the end process of the
experiment in the scientific method?
Experimentation
Which of the following processes is considered to be “the heart of
science”?
Pot 1 is the control group, Pot 2 is the experimental group, and
water is the independent variable.
In a controlled experiment, a lab researcher grows peas in two
different pots to study their sprouting time. Pot 1 is devoid of water,
whereas pot 2 is constantly taken care of by providing sufficient water,
soil, and light conditions. Which of the following statements is true
about this experiment?
2 Hydrogen and 1 Oxygen
What is the correct number of atoms in one molecule of water?
Covalent bond
The hydrogen atoms in a water molecule are linked to the
oxygen atom by a(n) _.
Uneven distribution of partial charges
The polarity of a water molecule is due to the _ _.
