SCIENCE, TECHNOLOGY, ENGINEERING AND MATH
This department gives 4-H members an opportunity to display their knowledge and skills gained relating to computers, drones, electricity, energy, geospatial, robots, rockets, drones, welding and woodworking. Through participation in this department, 4-H members will present their knowledge in these areas as they relate to STEM.
All exhibits must be labeled. Label each item with the exhibitor name, project division, exhibit class number and years in the project before entering at county fair. The name and county of each exhibitor should appear separately on the back of each board, poster or article and on the front cover of the notebooks so owner of exhibit may be identified if the entry tag is separated from the exhibit. Each individual is limited to one exhibit per class. All static exhibits must have received a purple ribbon at the county fair to advance to the State Fair.
Several classes require a display board which should be a height of 24 inches and not to exceed 1/4" in thickness. A height of 23 7/8" is acceptable to allow for the saw kerf (width) if two 24-inch boards are cut from one end of a 4' X 8' sheet of plywood. Nothing should be mounted within 3/4" of the top or bottom of the board. (Example: Woodworking & Electricity.) For the safety of the models, models must be brought to the fair on a steady surface. Board such as plywood, composition board, or particle-type lumber must be used for demonstration displays and LEGO models.
Fabricated board such as plywood, composition board, or particle-type lumber may be used for demonstration displays.
Demonstration boards should be sanded and finished to improve their appearance. The finish on a demonstration board will be judged as a woodworking exhibit. Demonstration boards should include an overall title for the display, plus other necessary labeling.
Reports should be written using the scientific method whenever possible (background, the question or hypothesis, what you plan to do and what you did, method used and observations, results: what you learned. All reports should be computer generated and enclosed in a clear, plastic cover. The reports should be attached securely to the display.
4-H’ers can exhibit in only one level, and once they have progressed to a higher level they cannot exhibit or enroll in a lower project level. This does not apply to Aerospace Model Rockets Levels 3 and 4 and Woodworking Levels 3 and 4.
Premier 4-H Science Award is available in this area.
VETERINARY SCIENCE
*Denotes State Fair Entry
The purpose of a Veterinary Science exhibit is to inform the public about a common health problem of animals or a veterinary science principle or public health/zoonotic diseases.
1. A Veterinary Science exhibit may consist of a poster, notebook, or a display. The exhibit may represent material from any of the Veterinary Science projects including entry level exhibits from Unit I.
2. If photographs are to be part of the exhibit, remember that they will be viewed by the public. Make sure that the photographs are in good taste and will not be offensive to anyone. Graphic photographs of excessive bleeding, trauma or painful procedures are not appropriate. For exhibits related to veterinary surgical procedures, aseptic techniques need to be shown, for example, use of drapes, use of sterile procedures, wearing of gloves, and other appropriate veterinary medical practices. Premier 4-H Science Award is available in this area at the State Fair.
3. First-Aid Kits: Because of public safety concerns and risk of theft of first-aid kit contents (veterinary drugs/equipment) with perceived potential for drug abuse, animal first aid kits containing any drugs, medications, or sharps (including needles and scalpel blades) will be disqualified and not displayed. First Aid kits wishing to include medication information should instead utilize written descriptions, photographs, drawings, computer generated print-outs or empty packaging of pharmaceuticals.
4. Veterinary Science Posters: This exhibit presents the viewer with a design that is simple and direct, unlike a display that usually presents more information. A poster should not exceed 22 inches by 28 inches and may be either vertical or horizontal.
5. Veterinary Science Displays: A display may include but is not limited to: a three-dimensional exhibit, a scale model, the actual product (for example: skeleton; teeth; samples of leather, fur, or dried skin damaged by disease or parasites) or a notebook. A display is not a poster. A display may be mounted on poster board not to exceed 22 inches by 28 inches or on ¼-inch plywood or equivalent that does not exceed 24 inches high or 32 inches wide or in a three-ring binder or another bound notebook format.

Through participation in this category 4-H’ers will show judges what they learned about and how they adapted their exhibit throughout this project. Involvement in STEM Rockets gives participants a first-hand experience in modern technology.
Rocket must be supported substantially to protect the rocket from breakage. Rockets are to be mounted on a base that has dimensions equal to or less than 12 inches by 12 inches, and the base should be ¾ inch thick. No metal bases. If the rocket fins extend beyond the edges of the required base (12 inches by 12 inches), then construct a base that is large enough to protect the fins. The base size is dictated by the size of the rocket fins. The rockets must be mounted vertically. Please do not attach sideboards or backdrops to the displays. In addition, a used engine or length of dowel pin should be glued and/or screwed into the board and extended up into the rocket’s engine mount to give added stability. Rockets must be equipped as prepared for launching, with wadding and parachute or other recovery system. Rockets entered with live engines, wrong base size, or side boards will be disqualified.
Reports should be written using the scientific method whenever possible (Background, the Question or hypothesis, what you plan to do and what you did, Method used and observations, Results: What you learned, all reports should be computer generated and enclosed in a clear, plastic cover. The reports should be attached securely to the display.
An accompanying report typed, protected in a clear plastic cover, must include:
1. Rocket specification (include original or photo of manufacture packaging stating rocket skill level)
2. A flight record for each launching (weather, distance, flight height)
3. Number of launchings
4. Flight pictures
5. Safety (How did you choose your launch site? Document safe launch, preparations and precautions)
6. Objectives learned
7. Conclusions
The flight record should describe engine used, what rocket did in flight and recovery success. Points will not be deducted for launching, flight or recovery failures described. This includes any damage that may show on the rocket. Complete factory-assembled rockets will not be accepted. Rockets from all skill levels will be accepted. Judging is based upon display appearance, rocket appearance, workmanship, design or capabilities for flight, and number of times launched and report. Three launches are required to earn the maximum launch points given on the score sheets. For scoring, only actual launches count; misfires will not count toward one of the required three launches.
For self-designed rockets only, please include a digital recorded copy of one flight. In the documentation, please include a description of stability testing before the rocket was flown.
Several classes require a display board which should be a height of 24 inches and not to exceed ¼-inch thickness.

Purple, $3; Blue, $2; Red, $1.50; White, $1
This category helps 4-H’ers learn the basics of welding. In addition, 4-H’ers get the opportunity to present their knowledge on the topic and display what they have made. Involvement in STEM Welding gives participants a first-hand experience in a skill that can be used for a lifetime.
The name and county of each exhibitor should appear on the back of each board or article and on the front cover of the notebooks so the exhibit may be identified if the entry tag is separated from the exhibit. Each exhibitor is limited to one exhibit per class.
Display boards should be a height of 24 inches and not to exceed ¼ inches in thickness. A height of 24 7/8 inches is acceptable to allow for the saw kerf if two 24-inch boards are cut from one end of a 4-foot by 8-foot sheet of plywood. Nothing should be mounted within ¾ inch of the top or bottom of the board. Fabricated board such as plywood, composition board, or particle-type lumber may be used for demonstration displays. Demonstration boards should be sanded and finished to improve their appearance. Demonstration boards should include an overall title for the display, plus other necessary labeling.
Reports should be written using the scientific method whenever possible (background, the question or hypothesis, what you plan to do and what you did, method used in observation, results: what you learned.) All reports should include 4-Her name and county, be computer generated and enclosed in a clear, plastic cover. The reports should be attached securely to the display.
Welding joints and position: All welds exhibited in class 1 or 2 must be mounted on a 12-inch-high by 15-inch-long display board of thickness not to exceed 3/8 inch. Attach each weld on a wire loop hinge or equivalent, so the judge can look at the bottom side of the weld when necessary. Each weld should be labeled with type of welding process (stick, MIG, TIG, oxy-acetylene, etc.), kind of weld, welder setting, electrode/wire/rod size, and electrode/wire/ rod ID numbers. Attach a wire to the display board so it can be hung like a picture frame. No picture frame hangers accepted. If no plans are included with welding article or welding furniture, it will be disqualified. All outside projects MUST have entry tag and supporting information placed in a protective bag to prevent damage from weather events such as rain and be ATTACHED to projects with string, zip ties, etc.
*H920001 Welding Joints — A display of one butt, one lap and one fillet weld.
1. All welds should be made with the same electrode/wire/rod size and number.
2. Welds should be made only on one side of metal so penetration can be judged.
3. Welds should be cleaned with chipping hammer and wire brush. Apply a coat of light oil (penetrating oil) to the metal to prevent rusting. Wipe off excess oil.
4. It is suggested that all welds be on pieces of metal that are the same size and thickness. These pieces, referred to as coupons, should be 1½ to 2 inches wide and 3½ to 4 inches long. A good way to get this size is to buy new cold-rolled strap iron and cut to length. The extra width is needed to provide enough metal to absorb the heat from the welding process and prevent the coupons from becoming too hot before the bead is completed. Narrower coupons will become very hot, making an average welder setting too cold at the bead start, just about right in the middle, and too hot at the end. The correct way to weld narrow strips is to make short beads and allow time to cool; however, this project requires a full-length bead.
Stick welding — Suggested coupon thickness is ¼ inch if using 1/8-inch rod. Suggested rod for AC and DC straight or reverse polarity is first E-7014 and second E-6013.
MIG welding — Suggested coupon thickness is ¼ inch if using .035 wire and 1/8 inch if using .023 wire.
Oxy-acetylene — Suggested coupon thickness is 1/8 inch and suggested rod is 1/8-inch mild steel rod.
*H920002 Position Welds — a display showing three beads welded in the vertical down, horizontal and overhead positions.
1. It is suggested that all welds be of same size and thickness of metal. These pieces are referred to as coupons. The welds can be on one coupon that is about 4 inches by 4 inches or on individual coupons that are about 2 inches by 4 inches and ¼ inch thick. Suggested rods for this class of position welds for AC and DC straight or reverse polarity is first E-6013 and second E7014, and E-6010 for DC reverse polarity only.
2. Welds should be cleaned with a chipping hammer and wire brush. Apply a coat of light oil (penetrating oil) to the metal to prevent rusting. Wipe off excess oil.
