What, Why, and How, Categories

TNJSF offers two competitions to accommodate different types of student projects. Explore each competition to determine which best matches your work, then review the competition categories used for judging and awards.

Research and Engineering Design Competition (ISEF eligible)
What is a Research and Engineering Design Project?
A Research and Engineering Design Project is the implementation of the scientific method or engineering design process to answer a question or solve a problem. This involves conducting background research on the question or problem, forming a hypothesis or proposing a solution, designing and performing experiments or tests, analyzing the resulting data, and using the results to draw conclusions about the question or problem being investigated. In the TNJSF, the project may be in any area of Science, Technology, Engineering, or Mathematics (STEM).
Why Do a Research and Engineering Design Project?
This program allows students not only to learn about the scientific method and engineering design process, but also to gain real-world experience using them to address a question or problem in a STEM area that has sparked their interest.
By participating in the TNJSF Research and Engineering Design Competition, students will have the opportunity to discuss their work with judges and receive valuable feedback. They will also be able to explore a wide variety of research and engineering design projects and talk with other students participating in the fair during the public exhibition.
The TNJSF offers a wide array of cash prizes, awards, and opportunities to advance to other competitions. The Grand Prize for the Research and Engineering Design Competition includes advancement as Finalists to the Regeneron International Science and Engineering Fair (ISEF), the world’s largest international pre-college science competition, with all expenses paid.
How to Do a Research and Engineering Design Project
#1 Determine What Question or Problem You Want to Address
Think about scientific curiosities or engineering challenges from your own experience, topics you have studied in school, or issues you have learned about in the news. Then consider a what, why, or how question, or identify an unsolved problem related to your observation.
Once you have identified your question or problem, conduct background research to determine what is already known and what experiments, tests, or solutions have already been attempted. You may use books, journal articles, patents, reliable internet sources, and other appropriate materials. You must use at least five different sources of information for your background research.
#2 Choose an Adult Sponsor
All students must have an Adult Sponsor to participate in the TNJSF. You should choose an Adult Sponsor who can help guide you through the entire science fair process from start to finish. Consult the Sponsor requirements on the ISEF Roles and Responsibilities .
#3 Read the ISEF and TNJSF Eligibility Requirements, Rules, and Guidelines
It is very important that students, their Sponsors, and their parents or guardians read all applicable rules and guidelines before beginning work to ensure eligibility and compliance. This includes, but is not limited to:
  • ISEF Rules and Guidelines
  • ISEF Roles and Responsibilities
  • TNJSF Participant Eligibility and Ethics
  • TNJSF SRC Vertebrate Animal and Tissue Policy, if applicable
  • TNJSF SRC Human Participants policy, if applicable
  • All information on this website about the Research and Engineering Design Competition
Based on the rules, the Adult Sponsor should either have enough knowledge to ensure the safety of the student and compliance with all rules and regulations that apply to the project, or help the student find a Qualified Scientist and/or Direct Supervisor with the appropriate expertise. Qualified Scientists and Direct Supervisors must also read all applicable rules and guidelines.
#4 Plan Your Experiments or Tests and Write Your Research Plan
Based on your question or problem and your background research, you will formulate a hypothesis or propose a solution. You will then need to plan experiments or tests to evaluate your hypothesis or proposed solution. Be sure to consider what has already been attempted and what still needs to be investigated.
Project documentation should begin with the development of a Research Plan that explains the rationale, research question or engineering problem, materials, methodology and procedures, risk assessment, and bibliography for the proposed project. The Research Plan must be completed before experimentation or testing begins. Consult the Research Plan/Project Summary Instructions in the ISEF Rules and Guidelines.
#5 Determine Whether You Need Prior Approval from a Scientific Review Committee
Projects must be reviewed and approved by a local or regional Institutional Review Board (IRB) or Scientific Review Committee (SRC) before experimentation begins if they involve any of the following:
  • Human participants
  • Vertebrate animals
  • Potentially hazardous biological agents
  • Tissue or body fluids
  • Hazardous chemicals, activities, or devices
Students and their Adult Sponsors should consult the ISEF Rules and Guidelines, ISEF Checklist for Adult Sponsor (Form 1), ISEF Student Checklist (Form 1A), ISEF Approval Form (1B), and TNJSF SRC Vertebrate Animal and Tissue Policy, and TNJSF SRC Human Participants Policy to determine what supervision, safety measures, forms, and approvals are required.
To obtain Prior Approval from the TNJSF SRC, your project documentation must be completed in Terra Entry System. A preliminary ISEF Form 2C information must also be submitted when applicable. You must then submit a request in Terra Entry System for SRC Prior Approval.
#6 Begin Your Experiments and Enter the Fair
Once you have completed your Research Plan, Adult Sponsor Checklist, Student Checklist, and any other required forms, and have received all necessary approvals, you are ready to begin your experiments or tests. All work must follow the approved Research Plan.
You also can begin your entry in the Terra Entry System. Note that if your project was approved by the Supporting Adults before starting your entry in the Terra system, the Supporting Adults must be sure to enter the ACTUAL approval dates for the project, not the date they are submitting in the entry system.
Once experimentation begins, any changes to the project plan must be documented and reviewed for compliance with all applicable rules. Projects that received SRC Prior Approval must submit any proposed changes to the SRC for approval before those changes are implemented.
You must submit all required forms in the Terra Entry System before the applicable Entry Deadline.
#7 Prepare for Fair Day Judging
Students will prepare their project display and oral presentation. They should be ready to clearly explain their research question or engineering problem, methods, results, conclusions, and the work they personally completed.
Topic Presentation Competition (No experimentation)
What Is a Topic Presentation?
A Topic Presentation is an exploration of the current knowledge about a topic in any area of Science, Technology, Engineering, or Mathematics (STEM). Students can choose any topic within STEM that they find interesting or exciting. The sky is the limit!
Why Do a Topic Presentation?
This program allows students to explore and dig deeper into a STEM area that has sparked their interest and imagination. By presenting their topic at our in-person science fair, students will have the opportunity to discuss their scientific interests with judges and receive valuable feedback. They will also be able to explore the wide variety of Experimental Research projects and talk to other students participating in the fair.
How to Do a Topic Presentation
In a Topic Presentation, you explore a topic that YOU are interested in.
#1 Choose Your Topic!
Your topic should be in the broad areas of science, technology, engineering, or mathematics. You might choose a topic based on your own experience, something you have studied in school, or something you have seen in the news. Perhaps you know someone with diabetes or someone who owns a hybrid car. Your town may collect recycling or have several bridges. In short, look around you! Possible topics are everywhere when you let your curiosity guide you.
#2 Focus Your Topic!
Once you have chosen a topic, you will need to narrow your focus. Begin reading to identify the part of the topic that most sparks your curiosity. You can explore popular science sources such as Science News, Scientific American, and Popular Science, or begin with an internet search.
For example, climate change is a very broad topic. Climate affects many areas, including food production, animal migration patterns, and extreme weather events. You should choose one specific effect to investigate so that you can explore it in greater detail. You might examine relevant historical data or look for recent news articles.
#3 Dig Deeper into Your Topic!
After choosing your focus, begin searching for more detailed information. Your research may lead you to journal articles, patents, reports, or other specialized sources. Be sure to keep track of every source you use.
Requirement: You must use at least five different sources of information for your presentation.
#4 Organize Your Information and Write an Abstract!
What was your most interesting finding? Did you discover unanswered questions or unexpected information? Include these ideas in your presentation. Think carefully about how to focus on the most important things you learned.
You may want to write a report to help create a logical flow for your information. This will also help you prepare your abstract.
Go to the Prepare Your Abstract, Poster, and Presentation page for details.
#5 Enter the Competition!
Once you have organized your information and written your abstract, you are ready to enter the TNJSF Topic Presentations event.
Go to the Rules and Deadlines and How to Enter pages for complete instructions.
#6 Prepare Your Display for the Exhibition!
At the exhibition, you will present a poster describing what you learned about your topic.
Go to the Prepare Your Abstract, Poster, and Presentation page for details.
Important Reminders
REMINDER #1: Topic Presentations are all about LEARNING AND IMAGINING! Experiments, data collection, and models are not allowed.
REMINDER #2: Write the information in your topic description, abstract, and poster in your own words. All submissions will be scanned to check for plagiarism and AI-generated content.
What to Expect at the Exhibition
Once your Topic Presentation has been accepted into the Exhibition, you will present your poster to judges, explain what you learned during your research, and answer questions about your topic. The following information explains how Topic Presentations are judged and how awards are determined.
Judging Guidelines
Judging of Topic Presentations takes place on Sunday morning. During this time, judges will rotate between projects and meet with students one-on-one at their displays to evaluate their work. Each project will be evaluated by at least three judges during the judging period.
Students will orally present the information on their poster to each judge. Students will have approximately 10–12 minutes with each judge, including time for questions and answers.
At the end of the judging period, students may leave for lunch. The judges will then reconvene in the Judges’ Room to discuss the projects and determine which projects will receive awards.
The key areas of evaluation will be:
  • Scientific Understanding
    How deeply has the student studied the topic? How well does the student understand the science?
  • Creativity
    Does the student have a unique perspective or a creative approach to this topic?
  • Oral Presentation Skills
    Has the student explained the topic clearly and concisely?
  • Display Organization
    Is the student’s poster organized and easy to follow?
  • Ability to Answer Questions
    Is the student able to respond thoughtfully to questions from the judges?
  • Future Investigations
    Does the student have any unanswered questions or areas for further study?
  • References and Citations
    Does the information presented include appropriate citations, and is a complete list of all references provided?
