Identify Problem
4The problem is the question you want
answered.
Scientific discoveries often result from
curiosity. You might see something you
cannot explain. When you do, if you want
to find out about it, the question you ask is
your problem.

Make Observations
4Observations are anything that you notice
about the problem.
The first step towards solving the problem is
making more observations. The drawings
and other information you write down is
your data.

State Hypothesis
4A hypothesis is a likely explanation of the
problem.
Now you are ready to put your observations
and knowledge together. Think about your
observations and what you already know.
A hypothesis is not the answer, but it is a
possible answer. It must be tested.

Test Hypothesis
4Experiments are used to test hypothesis.
Testing is done through the collection of more
data, and, if possible, by doing experiments.
Anything in an experiment that can be changed
is a variable.. The setup of an experiment
should have only one variable changed at a
time. This way, you can be pretty sure that
the results of the experiment were caused by
that one variable. If possible, an experiment
should have a control-a setup that does not
have the variable being tested.

Collect Data
4Data are pieces of information from the
experiment.
The reason for an experiment is to collect
more information about the problem you
want to solve. The data might be written
descriptions, drawings, numbers, or any
other information you can record.

Study Data
4Decide what the information means.
Look at your data and think about what it all
means. To help study the data, you can
arrange some of it in charts and graphs.

Make Conclusions
4Decide if your data support your hypothesis.
Some of the discoveries you can make can be
shown by the graphs and charts you make
for your information. Your conclusion can
be related to your hypothesis. You could
come up with other hypothesis and test
them, too. In science, the answer to one
question just leads to other questions.
