The document is a guide on how to effectively conduct science projects, especially for students, highlighting the steps involved from topic selection to experimentation and conclusion formation. It emphasizes the importance of original ideas, well-defined objectives, and proper data presentation, while also mentioning notable science fairs and competitions. Additionally, it discusses challenges faced by students in environments with examination-based education systems, particularly in accessing resources and conducting experiments.

3. I live in Mainland China..
“The exam-based education system has
crushed nearly all of my spare time. And
how can I do the experiment without any
equipment? All schools love the examination
so no one will let a simple student to use the
equipment and research. And I must use a
proxy to visit websites like YouTube,
Twitter.So I think the people who have
submitted Google Science Fair is lucky.”

Experimental projects employs numerical

data and graphs, (change one parameter
and collect data)
Descriptive projects gathers information
through visual observation and interviewing

(assessing biodiversity etc.)
Experimental Projects are discussed here.

7. Steps in Science Fair
Projects
 Select a Topic
 Gather Information
 Make a Hypothesis.
 Design, Conduct, collect data
from an Experiment.
 Reach a Conclusion (based on
)
data)
Science Projects

8. 1 Th R
The Research Topic
hT i
 Your research question i what you h
Y h ti is h t hope t
to
figure out.
 Select a topic familiar to you or get advice from a
scientist.
 Eg- How growth rate differ in open grown trees
and in plantation grown trees?
 Comparison of growth rates in open grown tress
and in plantation grown trees.

 Environmental Science
E i t lS i
 Zoology
 Botany
 Agriculture
 Computer Science
Research fields
 Chemistry For Sri Lanka Science
 Earth Science/Space Science and Engineering Fair
 Mathematics
 Physics

10. 2. Gather I f
2 G th Information
ti
 Learn everything about th t i (R i
L thi b t the topic. (Review
Literature)
 From book, magazines, the internet, talk to
p p
people and experts
p
 Initial Observations
Science Projects

11. 3. Make a Hypothesis
yp
 The h
Th hypothesis i what you expect t
th i is h t t to
happen in your experiment. (possible
answer to the problem)
 For th
F the research question about t
h ti b t tree
growth (above), the hypothesis might be,
"Open grown trees grow faster compared
Open
with forest grown trees"

12. 4. Experiment – Design
p g
 You can start with an experiment with one
variable.
 Consider your "sample size.".
 Location
 Experimental Material (What species?)

3. The P
3 Th Procedured
 Experiment – Measure tree diameter at 1.3m
above ground (diameter breast height - DBH) in
plantation trees and in open grown trees
 One variable = DBH with 2 levels (OG and PG)
( )
 Sample size = 50 trees from each level
 Should find a location that contains both types of
y
trees
 Species = teak
 Trees should be similar aged

 We can add another

15. 4. Experiment – Record data
(Results)
 Results are the data, or information, that
you collected. Your data should be in
numbers. Don't just write that the plants
"look bigger"; write down exactly how
much they grew.
 You can enter data in a table.
Science Projects

16. 4. Experiment – data
Present your results and give explanations

17. 5. Reach a Conclusion
 The
Th conclusion i what you l
l i is h t learned f
d from d i
doing
the experiment.
 In just a few sentences your conclusion explains
sentences,
what happened in your experiment and whether
it supported your hypothesis.
Above example = Open grown tress grow faster
compared with plantation grown trees
Science Projects

18. 5. Reach a Conclusion – Discuss
the results
 Discuss your results, whether you accept the hypothesis
or not. What are the reasons for doing so.
 What if your results do not support your hypothesis? That
is perfectly fine. You're not out to "prove" your hypothesis
but to test it. Think along the lines of "here's what I
here s
thought was going to happen, and here's what actually
happened." Then go on to explain why you think things
happened the way they did.
 Compare results with similar experiments carried out by
others.

19. What makes a good science p j
g project?
 Look for original ideas.
 Have a well-defined objective

 Understanding of the basic science b hi d th
U d t di f th b i i behind the
project topic.

20. What makes a good science p j
g project?
 Support your conclusion with with data and
S t l i ith ith d t d
results
 Put enough time and energy into your project.
 Clearly present your work. Judges look for well-
written abstracts with easy-to-follow visual aids
y
and clear and concise answers.
