Important Correction to 2023 ABC State Fair Rules

It has come to our attention that that the class descriptions for Architectural Block Construction (ABC) published in the Kansas State Fair book did not align with the rule set for this year. As such we are making an important correction to the 2023 ABC State Fair Rules to correct the difference between the rule set and the class descriptions.

You can see the state fair book here:

The current 2023 ABC class description reads as follows:

Introductory – Level 1 (about 1 – 3 years of experience)
5710 Level 1 Diorama. A diorama illustrating at least 2 architectural features beyond floors, ceilings, and walls.
Experienced – Level 2 (about 4 – 6 years of experience)
5711 Level 2 Diorama. A diorama illustrating at least 4 architectural features beyond floors, ceilings, and walls, and includes 1 or more motion elements.
Advanced – Level 3 (about 7 – 9 years of experience)
5712 Level 3 Diorama. A diorama illustrating at least 6 architectural features beyond floors, ceilings, and walls, and includes 2 or more motion elements.
Master – Level 4 (10 or more years experience)
5713 Level 4 Diorama. A diorama illustrating at least 8 architectural features beyond floors, ceilings, and walls, and includes 3 or more motion elements.

These descriptions do not fit with the wording and intent of the ABC rules for 2023. We are working with the State 4-H office to put out an advisory notice and correction to the class numbers for the Kansas State Fair. However it is possible some counties may have already included the incorrect class numbers in their county fair books.

For county/district 4-H Staff we recommend reviewing your county fair book to insure you are using the class descriptions below. If your county fair book has already been published and uses a copy of the State Fair rules for ABC you can notify youth and parents of this correction or leave the class descriptions as is. We strongly recommend working with your ABC judge to clarify the judging standards that will be used, and encourage you to follow the published 2023 ABC rule set and not the 2023 class descriptions. If your county fair book has not been published, we strongly encourage you to update the class descriptions for ABC.

For parents or youth in a county using the incorrect ABC class descriptions, we recommend contacting your county/district extension office to clarify expectations. If your county has not published their fair book yet please work with them to update the ABC class descriptions to reflect the corrections below.

Registering ABC exhibits for the Kansas State Fair. For exhibits that meet the 2023 State Fair criteria for ABC, the class descriptions will be updated to those below in the registration system. This means that when registering exhibits for the 2023 Kansas State Fair that you will need to insure the correct class number is used as the classes change from experience based to age based classes. Thus the class number may change for youth in counties that are not using the corrected class descriptions.

ABC Judging at the Kansas State Fair. The 2023 State fair judges will be informed to judge according to the published rules and corrected class descriptions.

The corrected 2023 ABC class descriptions are as follows:

Intermediate (ages 9-13)
5710 Interlocking brick diorama built from scratch.
Senior (ages 14 and up)
5711 Advanced Interlocking brick diorama built from scratch.

The 2023 classes are broken up by age to make it easier for parents, youth, and judges to determine the appropriate class to exhibit in. While not optimal, this should alleviate confusion.

Counties are also encouraged to create a county only class, for example 5713 or adding the letter ‘a’ to the end of 5710, for youth ages 7 and 8, who are ineligible for the 2023 Kansas State Fair to display in at their county fairs.

An advisor notice to this change will be posted on the State Fair rules page and counties/districts will be notified as well.

We are very sorry about the confusion this has caused. Should you have questions or need additional clarification you can use the contact page or reach out to the State 4-H office.

Thank your for your understanding,

2022 Kansas State Fair STEM Judges Training

Have you ever wanted to be immersed in how the STEM projects (Ag Mechanics, Architecture Block Creations, Astronomy, Computers Robotics, Rocketry, and UAS) are judged at the Kansas State Fair? Maybe you want to see if you have what it takes to be a STEM judge.

This year we have 10 openings for those interested in learning about how STEM projects are judged at the Kansas State Fair. Those selected will get to shadow judges in each of the STEM areas to understand how the each area is judged and the nuances of judging at the State Fair. Those who complete the rotations will be added to the list of potential STEM judges for future fairs. 

Judging Starts at Noon on Wednesday September, 7th. We ask those participating in this STEM judges training event arrive and check in by 11:30 AM. Judging of exhibits typically concludes around 5PM.

All participants in the STEM judges training need to be adult volunteers (19+ and no longer enrolled in 4-H) or extension agents. Prior experience judging at the county fairs is encouraged but not required. Youth who wish to participate in the preparation and placement of STEM exhibits can sign up as a volunteer for the Kansas State Fair through their county extension office.

Lunch will be provided for judges, volunteers, and judge training program participants.

You may complete the registration form for the judges training online HERE. Those selected will be notified before Friday, August 26th.

For question about the judges training program use the contact page on the Kansas STEM site.

2021 State Fair Forms Available

The 2021 State Fair forms are available and have been published in their respective areas on the website. You can use the navigation menu across the top to find the area you are looking for. If you have questions about the forms or any other STEM content please use the Contact us page and let us know.

I do apologize that this took longer than normal to publish. Even though the updates look simple, to do all of the processing on the forms requires that I find a large block of uninterrupted time to process and adjust elements.

Additionally this year we have added two new areas to the STEM Program, Ag Mechanics and Architectural Block Construction (ABC).

Ag Mechanics covers welding, brazing, and smithing. We know this year is a fairly limited size for the exhibits, this is because we don’t have all the accommodations worked out yet to support large exhibits. As those details are worked out look for expanded sizes in the years to come.

ABC isn’t called “Lego’s” because there are many types of interlocking blocks on the market and youth can use whatever block type they have available. We are also focusing on how this relates to architecture, the blocks are a medium for creating that architecture.

At the Kansas State Fair, the use of kits in ABC is prohibited. This is so youth are judged on their abilities to create from scratch, a block environment, instead of following someone else’s instructions. Which could potentially turn this division into a money competition in my personal opinion. (Have you looked at the price of sets? If someone can afford a really complex set that puts others at a disadvantage before the judging has even started. Without sets in the mix there is a more level playing field. )

We are looking forward to an exciting year!



2020 KSF – Best In Show

For the last 20 or so years the STEM division (Astronomy, Computer Systems, Robotics, Rocketry, and UAS) judges have had a tradition where while they judge they look for entries that are considered “Best In Show.” There are no defined rules that distinguish a rocket as “best in show,” it is entirely at the discretion of the judges. These best in show exhibits are not just purple award winning entries, but entries that exemplify the 4-H motto, “to make the best better.”

Normally these exhibits are placed in special case(s) at the Kansas State Fair (KSF) in Hutchinson. With the pandemic this year, that obviously didn’t happen. However exhibits were judged remotely and there were several that caught the judge’s eyes.

Since we are unable to put them special case we want to post them here so they get the recognition they have earned by being best in show at the Kansas State Fair this year. Additionally if you would like to see all of the Kansas State Fair results please visit the State Fair results page.

In no particular order the following are the 2020 Kansas State Fair STEM divisions best in show.

2020 Kansas State Fair Virtual Exhibit Packets

The 2020 Kansas State Fair 4-H SpaceTech exhibits are going virtual. Below you will find the forms for each of the SpaceTech exhibit classes. These are designed to provide a consistent experience for both youth and judges.

You can see an example of the rocketry exhibit form completed to give you and idea what a submission would look like.

Rocketry, Robotics, and computer Systems classes require a video. Rocketry will accept optional videos but they are not required.

Exhibit Packets:

Below are the items required for each division and class. Note that items in column 1, 2, 3, & 4 are required to be included with your virtual exhibit. Following the table are some additional details.

Display Picture – All Exhibits need a display picture, this is what will be displayed publicly for the exhibit, this is what everyone will see. Other content is for judging purposes.

Link to Video Presentation – For many of the divisions a video is required. We encourage these be uploaded to YouTube or other video sharing service and adding the video as “unlisted” and then providing the link to the video. The video can the be removed after September 9th. Rocketry exhibits do not require a video, we welcome those who wish to share a video with the judges about their rocket but it is not required.

Display Packets – These are like the exhibit packets that are constructed for STEM exhibits each year, in addition to the traditional forms we are asking that you include some extra pictures to enable judging typically top, bottom, and side views of the rockets. All of these packets can be downloaded from this page. They are PDFs that are form fillable which allows you to just click and add pictures and information. To use the forms you will need to save it to your computer and open it in Adobe Acrobat Reader as most web browsers do not support forms in PDFs. Once done you can save the change made to the PDF. Realize that the PDF may become quite large and take a while to transfer. For best results we recommend cropping images to just the exhibit.

Code – Several projects require source code, some source code is picture based such as Ozobots and NXT’s others use lots of text files. The State Fair system does not support many of these file types, so what we encourage everyone to do is for pictures of code, place the pictures of the code in a PowerPoint file one after the other or a Word document. For text based content, the code should be pasted into a word document or printed out as a PDF. To print to a PDF in Windows 10, you can use the “Microsoft Print to PDF” printer under print function for your application.

Journals – For the computer systems project journals are required, these should already be typed up and will just need saved as a Word document, PDF, or PowerPoint File. To print to a PDF in Windows 10, you can use the “Microsoft Print to PDF” printer under print function for your application.

Plans – For rockets, robots, and unmanned aerial systems that are designed by the exhibitor (DbE) plans are required. These should be in a Word, PDF, or PowerPoint Document. These describe how to construct your exhibit and should be a detailed as possible. To print to a PDF in Windows 10, you can use the “Microsoft Print to PDF” printer under print function for your application.

Signatures – Some projects ask for signatures, to simplify the packets we are waiving the signature requirements.

Please Note: For rocketry, rockets DO NOT need to be launched this year, as there have been several counties that have been under a burn ban due to dry conditions. Also for rocketry, the video is optional, and it can be anything about the rocket, from youth talking about it to just a video of the rocket its self. The video just provides the judge with additional context and the ability to look at the rocket.

Please Note: (8-26-20) For robotics, the section in the exhibit packet titled “One or more photographs of the robot during construction” is meant to represent the “one to three pages of project photographs” as described in the rules. Typically project photographs happen at the beginning, middle or end of constructing a project. (Parts needed to construct, parts being assembled, and my completed robot.) Judges will be provided clarification regarding this as part of their orientation. We encourage youth to document the progress made throughout the creation of their projects, this documentation is not only beneficial for the judges, but also in the record keeping process.

If you have questions about completing the packets or any of materials and how they need to be prepared for the state fair this year please use the contact page.

Rocket launches and fire safety


This is a safety reminder about Kansas 4-H rocketry rules as they relate to fire bans in Kansas. While many parts of Kansas have recently experienced strong storms, we know that weather conditions can change rapidly, often in only a few days or weeks.  The 2020 Kansas State Fair rocketry rules state “if a fire burn ban is in effect for any county in Kansas, exhibitors in any Kansas county are not required to launch their rocket(s).  All requirements for the launching of rockets for the state fair and the documenting of the launching are suspended for the duration of the ban.” We advise all counties to always be cautious and use good judgment in planning and conducting county rocket launches, and consider cancelling them if dry conditions warrant. If you have comments or questions, please use the contact us page, or reach out to your local count extension office or the State 4-H office.

If you wouldn’t light a match and throw it on the ground you shouldn’t launch a rocket.

Stay safe with your rocketry endeavors.

Remote Control Robots vs. Remote Controlled Cars

Today I got the question: Is a robot with a remote control that takes a step with each press of the remote (walks) the same as a remote controlled car? Rule 9 in robotics for the Kansas State Fair states: “Remote controlled robots are allowed under certain conditions provided that the robot is not drivable.  Remote controlled cars, boats, planes and/or action figures, etc. are not allowed.”

Here is my interpretation of Rule 9 for the Kansas 4-H SpaceTech Robotics as published for 2019 Kansas State Fair.

The big question on this is what are the “series” of actions that occur each time you press the button?

If you press the button and the logic for the button press, for example, is spin motor for 5 seconds or 200 degrees or until you let go of the button and that’s all that happens. Then it’s the same logic as a remote controlled car. You press the button and it moves forward and that is the only thing in the logic “series” that happens.

Now, if the robot has more sets of logic in the series, like spin motor 1 for 200 degrees, spin motor 3 for 90 degrees, leave motors 2 and 4 stationary, and then motors 2 and 4 repeat the 200 and 90 degree spins while motors 1 and 3 remain stationary. That’s a logic series of tasks, and that’s really the dividing line. If when you press the button more than one thing is happening for that button click (preferably with some form of condition like an “if” or a “while” statement) then there is a clear difference between remote control cars. In other words a whole series of things has to happen correctly for it to move forward, not just spinning a motor till you let go of the button.

For example if you built a remote controlled robot that did a figure 8 when you hit a button, that is a series of actions: turn left, keep left, keep left, turn right, keep straight, turn right, keep right, keep right, turn left, keep straight, repeat. The operator with the remote doesn’t have to know all the steps to perform a figure 8, the robot already knows them and the operator just has to know to push the button.

Example of a car’s, boat, action figures logic:

Standard Remote Controlled Car Logic when a button or lever is pressed. When pressed the Move operation is performed until the button is released.

Example of more sophisticated logic or a “series” of events that goes beyond a typical “remote control car” setup:

Advanced logic of a robot when a button is pressed. Start by doing task MOT1 then MOT3, after which a condition is evaluated. If true then task MOT1 and MOT3 are executed if False then MOT2 and MOT4 are executed.

This is why the rules ask for the copies of the code used for the robot. That way the judges can see the logic of how a robot functions, is it just a single thing that happens with the push of a button or is there more happening, something that shows the robot completing a task? (In this example 4 motors being logically orchestrated in a specific sequence to “walk” in a given manner.)

This is my interpretation of: Is a robot with a remote control that walks the same as a remote controlled car? Other judges and superintendents may interpret this rule differently and that is their desecration to do so.

If you need guidance feel free to post your remote control specific questions in the comments below or use the contact page to send your question to us.
