How to do a Science
Project?
| One of the most interesting
activities that you do during your school years is doing a Science Project. Some
schools require only one Science Project when the students are in the 8th grade.
Some other school have at least one science project each year. |

In any way
science project is your best opportunity to face the challenges that you may
have in real life when you want to start your own business or when you get a
job. Please note that doing science project is not inventing something. You must
gather as much information as you can and get as much help as you need.
Following are some of the resources that you may use:
Parents can help you in different
areas depending on their education and expertise. Parents presence, support and
supervision is an important part of any science project.
ScienceProject.com website
provides you with project guides and support by project advisors. Project guides
usually include background information, question, hypothesis, variables and
experiment design.
Encyclopedia.com and Wikipedia.com
provide you with general information about any subject.
MiniScience.com website provides
you with project ideas, project kits and material.
Local libraries provide you with
books and magazines about the subjects related to your project.
Local professionals or other
family members may have knowledge and expertise that can help you with your
project. Before you ask for this type of help, make sure your parents are
informed and agree with what you are doing.
Select a science project:
The first step in doing a science project is selecting a topic or a subject.
Most teaches allow you to select your own subject; however, they may need to
approve your idea before you start your project. Make sure you review your
school guidelines or requirements before selecting your science project. Choose
your project from the list of project ideas and see the introduction page for
any project that you might be interested in.
Primary
Projects are for students from 1st grade up to 4th grade. Most of
these are classified as observation and display projects.
Elementary
projects are for 6th grade and 7th grade students. At this level
projects may be display or experimental projects.
Intermediate
projects are for 7th and 8th graders. Most of the projects in this
category are experimental projects or investigatory projects.
Senior
projects are recommended for 9th grade to 12th grade students. Most
of these projects are experimental projects.
All Science Project ideas in the
above categories may be selected as a Science Fair Project or as a classroom
project. You may even be able to perform other variations of such projects.
Propose a question or purpose:
What do you want to
find out? Write a statement that describes what you want to do.
Use your observations and questions to write the statement.
Identify Variables:
When you think you
know what variables may be involved, think about ways to change
one at a time. If you change more than one at a time, you will
not know what variable is causing your observation. Sometimes
variables are linked and work together to cause something. At
first, try to choose variables that you think act independently
of each other.
Write your hypothesis:
Based on your gathered
information, make an educated guess about what types of things
affect the system you are working with. Identifying variables
is necessary before you can make a hypothesis.
Design an Experiment:
Design an experiment
to test each hypothesis. Make a step-by-step list of what you
will do to answer each question. This list is called an experimental
procedure. For an experiment to give answers you can trust, it
must have a "control." A control is an additional experimental
trial or run. It is a separate experiment, done exactly like
the others. The only difference is that no experimental variables
are changed. A control is a neutral "reference point"
for comparison that allows you to see what changing a variable
does by comparing it to not changing anything. Dependable controls
are sometimes very hard to develop. They can be the hardest part
of a project. Without a control you cannot be sure that changing
the variable causes your observations. A series of experiments
that includes a control is called a "controlled experiment."
Write a list of material:
Write your experiment Results:
Experiments are often
done in series. A series of experiments can be done by changing
one variable a different amount each time. A series of experiments
is made up of separate experimental "runs." During
each run you make a measurement of how much the variable affected
the system under study. For each run, a different amount of change
in the variable is used. This produces a different amount of
response in the system. You measure this response, or record
data, in a table for this purpose. This is considered "raw
data" since it has not been processed or interpreted yet.
When raw data gets processed mathematically, for example, it
becomes results.
Write a summary of your
results:
Summarize what happened.
This can be in the form of a table of processed numerical data,
or graphs. It could also be a written statement of what occurred
during experiments.
It is from calculations using
recorded data that tables and graphs are made. Studying tables
and graphs, we can see trends that tell us how different variables
cause our observations. Based on these trends, we can draw conclusions
about the system under study. These conclusions help us confirm
or deny our original hypothesis. Often, mathematical equations
can be made from graphs. These equations allow us to predict
how a change will affect the system without the need to do additional
experiments. Advanced levels of experimental science rely heavily
on graphical and mathematical analysis of data. At this level,
science becomes even more interesting and powerful.
Draw a Conclusion:
Using the trends in
your experimental data and your experimental observations, try
to answer your original questions. Is your hypothesis correct?
Now is the time to pull together what happened, and assess the
experiments you did.
Related Questions and Answers:
What you have learned
may allow you to answer other questions. Many questions are related.
Several new questions may have occurred to you while doing experiments.
You may now be able to understand or verify things that you discovered
when gathering information for the project. Questions lead to
more questions, which lead to additional hypothesis that need
to be tested.
Possible Errors:
If you did not observe
anything different than what happened with your control, the
variable you changed may not affect the system you are investigating.
If you did not observe a consistent, reproducible trend in your
series of experimental runs there may be experimental errors
affecting your results. The first thing to check is how you are
making your measurements. Is the measurement method questionable
or unreliable? Maybe you are reading a scale incorrectly, or
maybe the measuring instrument is working erratically.
If you determine that experimental
errors are influencing your results, carefully rethink the design
of your experiments. Review each step of the procedure to find
sources of potential errors. If possible, have a scientist review
the procedure with you. Sometimes the designer of an experiment
can miss the obvious. Write
your References:
Write a bibliography to show your references in any form. Such information
include the form of document, name of writer, publisher, and the year of
publication. Write an Abstract:
Many people will not have time to read
a long project report. An abstract is a brief description of your project
purpose, experiment method, result and conclusion. Although you write an
abstract at the last step of your project, you must place your abstract in the beginning
of your report. |
