Exhibit List for Judges

2024 guidelines for picking exhibits to judge    hide

The table below shows the status of all the project we’ve registered so far. We expect to update it every couple of days, as we receive new registrations or paperwork. You can use it to pick the exhibits you’d like to judge, before you come to the Fair.

Things to consider:

  • We ask you to plan to judge at least 6 exhibits — more, if you have time.
    • Pick several extras, in case the ones you prefer have dropped out or are fully subscribed before you can sign up.
  • When picking exhibits to judge, avoid favoritism — or the appearance of it.
    • Don’t judge an exhibit if the student or adult sponsor is a relative, friend, or neighbor.
    • Avoid judging exhibits from a school in your neighborhood, that your children (or grandchildren) attend now, or that you or they used to attend.
    • It’s probably easiest if you just pick exhibits from cities other than your own.
  • Early arrivals get their pick of the exhibits and the doughnuts. Sign-up for divisions and exhibits is first come, first served. The later you arrive and check in, the more likely that the division or exhibits that you prefer will already be fully subscribed.
  • All the students deserve to be properly judged. To ensure that happens, we may need you to judge exhibits or a division that you would prefer not to.
    • As the Exhibit Counts by Division table on our Statistics Page shows, we usually have more junior exhibits than seniors, so we need more junior judges. Please consider judging a junior division.
      • Even if you have your heart set on judging seniors, consider picking some exhibits in a junior division, so you’re ready to go if we have to draft you as a junior judge.
    • If this is your first or second year as an EISEF judge, plan to judge in a junior division. Consider this part of your apprenticeship in judging.

Key to the table columns    hide

Exh.# /Div.

That’s “Exhibit number or Division”. The divisions are Junior Biological science (JB), Junior Physical (JP), Junior Teams (JT), Senior Biological (SB), and Senior Physical (SP). An exhibit number is just the division followed by a 2-digit serial number, like JT99. (Senior team exhibit numbers include a ‘T’, for example SB99T. Unlike the junior teams, they aren’t in a separate division.)
At first this column displays only the exhibit’s division. In the last week before the Fair, we assign exhibit numbers to the Accepted entries; by Wednesday or Thursday before the Fair, each exhibit will have its number. Each exhibit’s number is unique; it appears on the exhibit table and exhibit maps, on the score sheets (EISEF judging) and Green Sheets (sponsored award judging).

Status

Accepted: You can pick this exhibit to judge on Fair Day. Everything about the project is in order; we’ll be ready for the student at Student Check-in in Lindale Mall at 8:00 AM on March 16, 2024.
Pending: We received the student’s online registration; now we’re waiting to receive the project’s signed paperwork. Once we receive the paperwork, we’ll the change the status to Accepted.
Disqualified: The student broke the rules and won’t be permitted to check in or exhibit at the Fair. You shouldn’t pick this exhibit to judge.
Dropped: The student registered, then decided not to attend this year’s EISEF. You shouldn’t pick this exhibit to judge.

Student Name(s)

As you might expect, the name(s) of the student(s) who conducted the experiment and who you will interview.

Project Title and Description

These tell what the project is about, in the student’s own words. The title will appear on the exhibit, in the handouts you’ll receive on Fair Day, and elsewhere; it can be terse and uninformative. The description gives more detail; in the table, it appears below the title, in italics. Use both to help you pick projects you want to judge.

Adult Sponsor

The teacher or other adult who guided the student(s) in conducting the experiment and preparing the exhibit.

School and City

The student’s school and its location.

Entries received and processed through March 15, 2024.
