What is science? science is characterized by an organized approach
that is called the scientific method. the practical activity
encompassing of the systems study of a structure and a behavior of
the natural and the physical world.
2. What does it rely on? Science relies on the scientific method and
evidence to prove its findings.
3. What is the Scientific Method? The Scientific method is the 8 step
process used to solve problems. The 8 steps include collecting data ,
formulating hypothesis ,testing hypothesis ,and stating conclusion.
4. What are the two principles of the Scientific Method? The two
principles of the scientific method are uniformity and events in the
natural world.
5.List the eight steps of the Scientific Method with a brief explanation?
The eight steps of the scientific method are: observe, ask a question,
gather info, make a hypothesis, experiment, data, analyze, report
findings.
6.How does the Scientific Method generally begin?The scientific
method generally begins with an observation.
7. Describe a good hypothesis. Good hypotheses answer a question and
are testable in the natural world.They are also If-Then Statements.
do scientists test a hypothesis? Many scientists use a controlled
experiment to test their hypothesis.
Why should experiments be repeated? experiments should be
repeated when a hypothesis is false.

2. What variable is measured in experiments? The dependent
variable is the variable measured during experiments.
3. What is quantitative data? quantitative data is measured
using numbers.
4. How do biologists usually score results of an experiment?
biologist usually score the results of experimenting by using
one of their senses
5. What is the goal when analyzing data? the goal when
analysing data is to determine if the data is reliable or not and
if the hypothesis is supported or rejected by the data.
6. How do scientists analyze data? (3 ways) scientists analyze
data through observation, prediction, and experiment.
7.How do scientists display their data? Data is displayed using
tables, graphs, charts and other visual aids.
How do biologists draw conclusions? Biologists draw
conclusions By using the scientific method

2. What do testing predictions allow a scientist to do? Testing
predictions helps scientists to check if their hypothesis is supported
or rejected.
3. How do biologists test hypotheses? Biologists often test hypothesis
by setting up an experiment.
4. What is a controlled experiment? A controlled experiment compares
an experimental group and a control group and only has one variable
5. What is a control group? In an experiment, a group that serves as a
standard of comparison with another group which the control group
is identical except for one factor. The control group is your normal,
UNCHANGED group
6. What is the experimental group? An experimental group is identical
to a control group except for the independent variable
7. What is an independent variable? In a experiment the factor that is
deliberately manipulated; also called the manipulated variable.
8. What is a dependent variable? A dependent variable is the factor
change as a result of manipulation. The dependent variable is the
variable we measure.
2. What do they prove or disprove? Scientist use experiments to
prove or disprove a hypothesis.
3. Why is a hypothesis always only tentative in science? A
hypothesis is always tentative Because they must be tested in
order to be confirmed as true or false.
4. What is an inference? An Inference is a conclusion reached
on the basis of evidence and reasoning.
5. What do scientists do with their results? scientist create a
conclusion with the data/results they have received after
experimentation.
6. What is a theory? a theory is an explanation for some
phenomenon that is based on observation, experimentation ,
and reasoning; that is supported by a large quantity of
evidence; and does not conflict with any existing experimental
results or observations.
