The first step, selecting a project idea, is the most important. This is the first question or dilemma a student faces when starting a science project, because it can make the difference between a good and an excellent project.
Keep two important things in mind while selecting your topic: First, choose a topic that interests you; second, while you are choosing a topic, check all the resources around you. This will help you in doing your project with ease. e.g. - If you are doing a project on Eucalyptus leaves, ensure that you have the Eucalyptus tree in the surrounding region where you live.
After selecting your project topic, learn everything about it. You can use the many search engines available to find information or try various science related sites on the internet. In particular, do check the scientific literature by searching databases like www.scholar.google.com, www.scirus.com or www.pubmed.gov to see if related work has been done before.
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 independent of each other. At this point, you are ready to translate your questions into hypothesis. Hypothesis is a tentative theory that can be proved or disproved through further investigation and analysis. There is usually one hypothesis for each question you have. You must do at least one experiment to test each hypothesis. This is a very important step.
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 believe, it must have a “control.”
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. It is difficult to develop effective controls. Without a control, you cannot be sure that changing the variable causes your observations. A series of experiments that include a control is called a “controlled experiment”.
Experiments are usually repeated to guarantee that what you observe is reproducible. It is also repeated to obtain an average result. Reproducibility is a crucial requirement. Without it, you cannot trust your results. Think of possible errors and record them, or correct them if you can.
Your results should be predictable, i.e. the same results should be obtained when the experiment is repeated. It is useful to choose a statistical test that will validate your results. This will also ensure that your results are not due to mere chance but are scientific in nature.
During each experimental ‘run’, you measure how much the variable affects the system under study. Each change of variable produces a different response in the system. You measure this response or record data in a table for this purpose. These are considered “raw data”, since they have not been processed or interpreted yet. When raw data are processed mathematically, for example, they become results.
Observations can be written descriptions of what you noticed during an experiment or problems encountered. Keep careful notes of everything you do and everything that happens. Observations are valuable when drawing conclusions and useful for locating experimental errors.
However, maintain a record of experimental details and data-log book. Do not rely on your memory. Alternately, one can take photographs or video record a process of an experimental procedure performed. This will be an added proof for any experiment performed.
Discussion with your guide should be an ongoing activity. Your guide is very important in guiding you through your project until the end. He/ she will be able to give you all the required inputs to develop a research-based project. The guidance will ensure that you are working in the right direction and the methodology being used by you is correct.
Use your raw data to calculate and arrive at conclusions. For example, you weighed a container. This weight is recorded in your raw data table as “wt. of container”. Then you added some soil to the container and weighed it again. This would be entered as “wt. of container + soil”.
In the calculation section, do the calculations to find out how much soil was used in this experimental run: (wt. of container + soil) - (wt. of container) = wt. of soil used. Each calculated answer is entered into a table in a “Results” section, using proper units.
Summarise 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 on studying tables and graphs, you can see trends that tell us how different variables cause our observations. Based on these trends, you can draw conclusions about the system under study.
These conclusions help you to confirm or deny our original hypothesis. Often, mathematical equations can be made from graphs. These equations allow you to predict how a change will affect the system without the need to do additional experiments. Apply appropriate statistics to analyse your data so that valid conclusions can be drawn.
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 put together what happened and assess the experiments you did.
It is possible that your observations lead you to conclude something different from your starting hypothesis? Do not alter results to fit a theory. If your results do not support your hypothesis, it does not matter. You still have done successful scientific research. The spirit of scientific inquiry requires an open mind.
If your project involves making a ‘device’, then put down the estimated cost of all the components required for that device. You must do a cost comparison with the existing products, if applicable. You should also state the source from which these components can be obtained.
A synopsis gives the essence of the project in brief. Ideally, a synopsis should not exceed 250 words. Scientific Review Committee and other readers should have a fairly accurate idea of the project from reading the synopsis. The synopsis must focus on the current year's research and give only minimal reference to previous work as applicable. Details, discussions and acknowledgement should not be included in the synopsis, but may be put in the longer research paper or given on the project exhibit board.
A synopsis does not give details about the materials used unless they greatly influenced the procedure or had to be developed to conduct the investigation. A synopsis should only include procedures done by the student. Work done by a mentor (such as surgical procedures) or work done prior to student involvement must not be included.
The following should be the elements in your synopsis:
- Purpose of the experiment
- An introductory statement of the reason for investigating the topic of the project. A statement of the problem and/or the hypothesis being studied
- Procedures used in the experiment
- A summary of the key points and an overview of how the investigation was conducted
- Data - This section should provide key results that lead directly to the conclusions you have drawn. It should not give too many details about the results nor include tables or graphs
- Conclusion - Conclusions from the investigation should be described briefly. The summary paragraph should reflect on the process and possibly state some applications and extensions of the investigation
SYNOPSIS OF THE PROJECT THAT WON THE GRAND AWARD AT INTEL ISEF 2011
Recycling Rexine Waste : A Novel and Economic Approach
We have developled a novel and economic way of recycling rexine waste material by separating the fabric and polymeric components using cryogenic grinding technique in a modified kitchen mixer.
For this we had frozen the rexine waste in liquid nitrogen. Then it was grounded to separate the polymeric material and the cloth fibers. Later the polymeric material was used for making composite sheets and moulded articles. The cloth fibers can be used for several downstream applications.
We took 100 g rexine waste, washed in hot water, dried in sunlight and cut into small pieces. Then it was taken in a thermocol box and treated with liquid nitrogen for 2-3 min with all possible precautionary measures to make the rexine hard and brittle. The brittle rexine pieces were ground using the modified kitchen mixer for 5 min and seived (20meshes/inch) to sperate the cloth fibers from the polymeric powder. The polymeric powder was introduced into moulds at 120-130 deg C for 35-40 minutes and subsequently cooled to fabricate and composite sheets. Cloth fibers were sent for carding or making fiber boards.
We have introduced different waste fibers like jute wastes, cloth fibers from rexine waste, along with fillers like wooden waste powder etc to the polymeric powder for improvement of physical properties of the products. The finished products have been evaluated for mechanical and physical properties. Our products finds an immense application in furniture industry and also a substitute for MDF and plywood.
The Screening Report should present an accurate idea of your project to the Scientific Review Committee during the screening stage. It is a very important document and you need to fill it in completely, to indicate the what, why and how of the project.
It would include the following details:
- Origin of the idea
- Place of research and time frame followed
- Type of work done
- Present status of the project leading to future research plans
- Focus on the research methodology followed and the various resources utilized
- Important experimental results as quantitative values with proper units
- Key diagrams and graphs to support your research
- Financial aspects of the project including comparative costs with similar, available products and technology would help gauge the feasibility of the idea
The Scientific Review Committee would also like to know your creative contribution and the unique aspects of the project. Carefully read the sample synopsis, screening report and award winning projects at IRIS. This will give you an idea on the content as well as the expected standard of quality at IRIS.
Encourage, support, and guide your child. Make sure your child feels it is his/her project. Make sure the work is primarily the work of the child. Realize the main goal of a Science Fair project is to help your child use and strengthen the skills he/she has learned and develop higher-level skills.
The main goal should not be the ribbon or prize. Provide transportation to libraries, nature centres, or universities that can help your child find project information. Locate Internet access, either at home or at a school or library. Help your child design a project that is safe and properly supervised.
Help your child plan a mutually agreed upon timeline to prevent a last minute project. It is suggested you allow at least 12 weeks conducting an experiment and preparing the presentation. Do not worry or get upset if your child does not win a prize at the Science Fair. The skills the child has gained are worth all the effort.
Ideally, your project should have the following elements:
Project data book - The project data book should have accurate and detailed notes of your research.
Synopsis - This is a summary of your idea and should include the purpose of the experiment, procedure used, data, and conclusion.
Research paper - A research paper should be prepared and must be available along with the project data book with relevant written material. A research paper helps organize data as well as thoughts.
A good paper includes the following sections:
a. Title page:
Centre the project title, and put your name, address, school, and grade at the bottom right
b. Table of Contents:
Include a page number for the beginning of each section
The introduction sets the stage for your report. The introduction includes your hypothesis, an explanation of what prompted your research and what you hoped to achieve
This section describes how you did the study. Describe in detail the methodology used to collect your data or make your observations. Your report should be detailed enough for someone to be able to repeat the experiment from the information in your paper.
Include photographs or drawings of self-designed equipment. Also specify the material used in the study. The research work conducted by you may have taken more than a year. In such case, include this year's work only.
This is the essence of your paper. The results and conclusions should flow smoothly and logically from your data. Be thorough. Allow your readers to see your train of thought, letting them know exactly what you did. Compare your results with theoretical values, published data and expected results.
Include a discussion of possible errors. How did the data vary between repeated observations of a similar event? How were your results affected by uncontrolled events? What would you do differently if you were to repeat this project? What other experiments should be conducted?
This section describes the findings and conclusion of the project. Briefly summarize your results. Be specific, do not generalize. Never introduce anything in the conclusion that has not been discussed.
You should always credit those who assisted you, including individuals, business and educational or research institutions. Identify any financial support or material donations received, but do not put it on the display board.
h. Reference list:
Your reference list should include any documentation that is not your own (i.e. books, journal articles, include specific internet urls).
You can take guidance from your teachers, research scientists or any qualified person who is capable of guiding your research project.
Different projects can have different guides, however, only 1 guide should be assigned per project. The guide will have to certify that the work has been done under his/her supervision and that necessary care has been taken while carrying out research on living organisms, human subjects, recombinant DNA, controlled substances, nonhuman vertebrate animals, human and animal tissues, pathogenic agents, etc.
Students are allowed to conduct experiments at home, in school or in laboratories of research institutions, universities, and colleges or at other recognised research facilities. The data reflected in the report must not be more than 12 months old. However, the project could be an extension of earlier work done by the student.
If your project is shortlisted to be displayed at IRIS National Fair, then you may follow certain Display Guidelines to set up your project stall at the Fair.
Since you want to attract and inform interested spectators and Scientific Review Committee, make it easy for them to access your project and the results you have obtained.
a. Display –
Make the most of your space using clear and concise displays. The display is what shows the Scientific Review Committee and public what you did. It should look organized, neat and attractive. While color is nice, do not distract from your results with a lot of decoration or distracting features.
The focus is the work; the board is just to display the work. The same guidelines apply for this as do the paper: watch your grammar, spelling and wording. Again, all sections should be TYPED and computer generated. Please refer to the diagram below. Make sure the display reflects the current year's work only.
b. A good title –
Your title should be simple and must accurately represent your research.
c. Take photographs/ videos –
Many projects involve elements that may not be safely exhibited at the fair, but are an important part of the project. You might want to take photographs/videos of important parts/ phases of your experiment to use in your display.
d. Models –
Prepare a miniature of your project in case your prototype is too large to be transported or carried along.
e. Be organized –
Make sure your display is logically presented and easy to read. A glance should enable anyone (particularly the Scientific Review Committee) to locate the title, experiments, results, and conclusions quickly. When you arrange your display, imagine that you are seeing it for the first time.
f. Eye-catching display –
Make sure your display stands out. Use neat, colourful headings, charts, and graphs to present your project. Pay special attention to the labelling of charts, diagrams, graphs, and tables. Each item must have a descriptive title.
g. Correctly presented and well-constructed –
Be sure to adhere to the size limitations and safety rules when preparing your display. All forms required for the project should be displayed. Make sure your display is sturdy, as it will need to remain intact for quite a while.
Maximum project sizes include all project materials, supports, and demonstrations for public and Scientific Review Committee. If a table is used, it becomes part of the project and must not itself exceed the allowed dimensions nor may the table plus any part of the project exceed the allowed dimensions.
Any project with a component that will be demonstrated by the Finalist must be demonstrated only within the confines of the Finalist’s booth. When not being demonstrated, the component plus the project must not exceed allowed dimensions. Table or freestanding display must be parallel to and postitioned at the back curtain of the booth.

f. Laboratory/household chemicals. (Exceptions: water integral to an enclosed apparatus or water supplied by the Display and Safety Committee)
g. Poisons, drugs, controlled substances, hazardous substances, or devices (e.g., firearms, weapons, ammunition, reloading devices)
h. Dry ice or other sublimating solids
i. Sharp items (for example syringes, saw blades, needles, pipettes, knives etc.)
j. Flames or highly flammable display materials
k. Batteries with open top cells
l. Awards, medals, business cards, flags
m. Photographs or other visual presentations depicting vertebrate animals in surgical techniques, dissection, necropsies, other lab techniques, improper handling methods, improper housing conditions, etc.
n. Identity of the student on the posters in any form
