ACTUAL EXAM 400 QUESTIONS AND CORRECT
DETAILED ANSWERS WITH RATIONALES|ALREADY
GRADED A+
Standard deviation - ANSWER: Measures the variability of a data set and determines
the amount of confidence one can have in the conclusions.
Regression Analysis - ANSWER: A method of analyzing sets of data and sets of
variables that involves studying how the typical value of the dependent variable
changes when any one of the independent variables is varied and the other
independent variables remain fixed.
Range - ANSWER: The difference between the highest and lowest numbers, which
can be used to determine how spread out data is.
Mode - ANSWER: The value that appears most frequently in a data set.
Median - ANSWER: The middle number in a list of numbers sorted from least to
greatest. If the list has an even number of entries, it is the smaller of the two in the
middle.
Mean - ANSWER: The sum of a list of numbers divided by the number of numbers.
James Watson and Francis Crick - ANSWER: Co-discoverers of the structure of
deoxyribonucleic acid (DNA), which has a double helix shape. The discovery of the
double helix shape was important because it helped to explain how DNA replicates.
DNA - ANSWER: Deoxyribonucleic acid that contains the code of genetic information.
Gregor Johann Mendel - ANSWER: Famous for experimenting with pea plants to
observe the occurrence of inherited traits. He eventually became known as the
father of genetics.
Barbara McClintock - ANSWER: She created the first genetic map for maize and was
able to demonstrate basic genetic principles, such as how recombination is an
exchange of chromosomal information.
Barbara McClintock - ANSWER: She also discovered how transposition flips the
switch for traits. Her work contributed to the field of genetics, in particular to areas
of study concerned with the structure and function of cells and chromosomes.
Carl Linnaeus - ANSWER: Created a method to classify plants and animals, which
became known as the Linnaean taxonomy. This was an important contribution
because it offered a way to organize and therefore study large amounts of data.
,Anton Van Leeuwenhoek - ANSWER: Used homemade magnifying glasses to become
the first person to observe single-celled organisms. He observed bacteria, yeast,
plants, and other microscopic organisms. His observations contributed to the field of
microscopic organisms. His observations contributed to the field of microbiology.
Charles Robert Darwin - ANSWER: Best known for contributing to the survival of the
fittest through natural selection theory of evolution by observing different species of
birds, specifically finches, in various geographic locations. Although the species
Darwin looked at were different, he speculated they had a common ancestor.
Charles Robert Darwin - ANSWER: He reasoned that specific traits persisted because
they gave the birds a greater chance of surviving and reproducing. He also
discovered fossils, noted stratification, dissected marine animals, and interacted with
indigenous peoples.
Charles Robert Darwin - ANSWER: He contributed to the fields of biology, marine
biology, anthropology, paleontology, geography, and zoology.
Scientific Notation - ANSWER: Used because values in science can be very large or
very small, which makes them unwieldy.
Significant figures and estimation - ANSWER: The mathematical concept of
significant figures or significant digits is often used to determine the accuracy of
measurements or the level of confidence one has in a specific measurement.
Scientific Method - ANSWER: 1. Identifying a problem or posing a question
2. Formulating a hypothesis or an educated guess
3. Conducting experiments or tests that will provide a basis to solve the problem or
answer the question
4. Observing the results of the test
5. Drawing conclusions
Scientific Fact - ANSWER: An objective and a verifiable observation
Scientific theory - ANSWER: This is a greater body of accepted knowledge, principles,
or relationships that might explain a fact.
Hypothesis - ANSWER: An educated guess that is not yet proven. It is used to predict
the outcome of an experiment in an attempt to solve a problem or answer a
question.
Law - ANSWER: An explanation of events that always lead to the same outcome. It is
a fact that an object falls. The law of gravity explains why an object falls.
Theory or Theories - ANSWER: Although they are generally accepted, they have not
been proven or disproven.
, Model - ANSWER: This is used to explain something on a smaller scale or in simpler
terms to provide an example. It is a representation of an idea that can be used to
explain events or applied to new situations to predict outcomes or determine
results.
Scientific Knowledge - ANSWER: It is constantly evolving. The body of facts, models,
theories, and laws grows and changes over time. One scientific discovery leads to the
next.
Scientific Knowledge - ANSWER: Science as a whole and its unifying concepts and
processes are a way of thought that is taught throughout a student's K-12 education.
Eight areas of content - ANSWER: 1. Unifying concepts and processes in Science
2. Science as inquiry
3. Physical Science
4. Life Science
5. Earth and Space Science
6. Science and Technology
7. Science in Personal and Social Perspectives
8. History and Nature of Science
Specific Unifying Concepts and Processes included in the standards and repeated
throughout the content areas - ANSWER: 1. systems, order, and organization
2. evidence, models, and explanation
3. change, constancy, and measurement
4. evolution and equilibrium
5. form and function
SI units of measurement - ANSWER: The International System of units.
The ampere - ANSWER: This is used to measure electric current.
The kelvin - ANSWER: This is used to measure thermodynamic temperature.
The candela - ANSWER: This is used to measure luminous intensity.
The mole - ANSWER: This is used to measure the amount of substance at a molecular
level.
One of the five abilities that 5-8 students need to acquire - ANSWER: They should be
able to reformulate and clarify questions until they can be answered through
scientific investigation.
One of the five abilities that 5-8 students need to acquire - ANSWER: They should be
able to create and carry out a scientific investigation, interpret the data to provide
explanations, and use further data to revise explanations.
