the long term impact."-Bill Gates
River Valley Middle
School Science Fair
A GrassRoots Project Project Involving
Students, Teachers and Schools across New Brunswick
River Valley Middle School hosted a School Science Fair
for grades 6 through 8. Students prepared and submitted Science projects
which tied into the Science curriculum outlines for evaluation and information
transfer.
Students promoted the event through use of Technology and Language Arts
in both official languages. Students investigated middle school grade
specific science and design projects that best achieved their desired
outcomes.
The main activities were science and technology based experiments that
were displayed for viewing at the school by local area students, teachers
and parents.
Winners of the school science fair moved the district 8
science fair for the next level of competition. Winners from this competition
moved to the provincial science fair.

Why have a science fair?
Educators understand that most people learn best through personal experience.
As human beings, we explore, inquire, discover, and understand more and
more about the world around us. Students need to be given opportunities
to ask questions, design investigations and make meaning out of the data
collected. In order for these skills to be developed, the focus of science
education needs to shift from having students "watching it being
done" to actually "doing science".
An event such as a Science Fair is a great medium to have all students
pursue "their own" investigations to answer "their own"
questions. Here at River Valley, we experienced such an event this past
year. Around 225 students displaying over 145 exhibits proudly shared
what they discovered. We have included some information on our school's
web site to help teachers in preparing their students to experience a
"Science Fair."

How do I prepare students for a science
fair?
1) Selecting a topic
The first and most important step is to get students to
ask questions about what intrigues them. Something that bugs them...that
they want to understand. Teachers can give the following examples of some
students' process to develop a topic.
· A father and his son were getting ready to go on a fishing trip.
They wondered about what kind of batteries would last the longest. They
designed an experiment using five different brands of batteries based
on the assumption that the most expensive one would be the best. After
testing the life of each battery, they discovered their hypothesis to
be correct.
· A 13-year-old girl wondered if ice cream was responsible for
headaches when eaten too fast. She conducted an investigation with an
experimental and a control group. One group ate 30ml of ice cream as fast
as possible. The other group had the same quantity to eat over a certain
period of time, having to leave some in the bowl.
The purpose is to awaken the students to the fact that a "Science
Fair" project does not have to very complex and elaborated. We can
find ideas all around us, if we stop and take the time to observe. Students
need time to ponder for a few days. After a few days of reflection, students
need to formulate questions that lead to an investigation. There is a
difference between a question that leads to an investigation and one that
leads to a library research. Here are some examples:
|
"Investigation" questions
· Does your pulse rate increase or decrease after listening
to some music?
· Which frozen liquid melts the fastest: milk, water or soda
pop?
· Does the size of the wheels of a toy car affect the distance
it travels?
|
"Library research" questions
· How is dew formed?
· How does dishwashing soap clean oil away?
· What keeps an airplane in the air?

2) Research the topic
Once students have identified a "question" they
want to answer, the next step is to learn as much as possible on the subject.
Teachers may give research time at the library or on the Internet. The
object is to be prepared to form an intelligent testable hypothesis.
3) Design an investigation
This step allows students to focus their attention on the
details of the investigation. They formulate an hypothesis that can be
easily verified with an experiment. The plan needs to include the following:
· Materials needed
· Variables involved
· Detailed procedure
· Data collection plan
Teachers may use the handout to help students narrow their
thoughts down to the necessary information. Each plan needs to be approved
by the teacher. At first, students will need assistance to develop their
experimental design.
4) Conduct the investigation
This phase where students actually do the experiment, can
happen at home. During the experiment, students can take pictures, record
data and keep detailed notes of observations.
5) Analyze results
When the experiment is over, students compare the results
with their hypothesis and form a conclusion. They need to establish if
their hypothesis was confirmed or not. At this point students may have
found new questions to be answered and suggest new variables, different
materials or procedure for another investigation.
6) Write the report
Writing a report about all that was done, how it was done
and what was discovered, is an important aspect of a Science Fair Project.
Scientists need to communicate their investigations clearly to allow others
to conduct the same investigation and arrive at the same conclusions.
7) Making a display
The display says it all about the project. It needs to be
neat and organized onto a self-standing background that can be put on
a table. It should be self-explanatory and take no more than 5 minutes
for an audience to understand from beginning to end.
