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. One exhibit per class unless otherwise noted. Several classes require a display board which should be a height of 24” and not exceed 1/4" in thickness. A height of 23 7/8" is acceptable to allow for the saw kerf (width) if two 24” boards are cut from one end of a 4'x8' sheet of plywood. Nothing should be mounted within 3/4" of the top or bottom of the board. Fabricated boards such as plywood, composition board, or particle-type lumber may be used for display boards. Display boards should be sanded and finished to improve their appearance. The finish on a display board will be judged as a woodworking exhibit. Display boards should include an overall title for the display, plus other necessary labeling. Reports should be written using the scientific method whenever possible (Hypothesis, Research, Experiment, Measure, Report or Redefine Hypothesis). All reports should be computer generated, enclosed in a clear, plastic cover, and attached securely to the display. If the project is designed to be used outdoors, it may be displayed outdoors.
Posters can be any size up to 28”x22” when ready for display. Tri-fold poster boards exceed 28”x22” when open for display, so are not accepted.
Division 850: STEM Rockets/Drones
One exhibit per class unless otherwise noted. Rockets must be supported substantially to protect the rocket from breakage. Rockets are to be mounted on a 3/4" thick base that has dimensions equal to or less than 12"x12". No metal bases. If the rocket fins extend beyond the edges of the required base (12”x12”), 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 display. A used engine or length of dowel pin is to 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 sideboards will be disqualified. A report, protected in a clear plastic cover, must include: 1) rocket specification (include original or photo of manufacturer 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 and 7) conclusions. The flight record should describe engine used, what the 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. Judging is based upon display appearance, rocket appearance, workmanship, design or capabilities for flight, number of times launched and report. Three launches are required to earn the maximum launch points given on the score sheets. Misfires will not count as one of the required three launches. Scoresheets can be found at https://go.unl.edu/ne4hstem.
For self-designed rockets only, please include digital recorded copy of one flight. In the documentation, please include a description of stability testing before the rocket was flown. Skill level is determined by the level listed on the manufacturer’s packaging. 4-H Rocket project levels are not intended to correspond to National Association of Rocketry model rocket difficulty ratings or levels.
High power rockets (HPR) are similar to model rocketry with differences that include the propulsion power and weight increase of the model.

4-H Welding Project Tips and Suggestions
CLASS 1
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 of the same size and thickness as metal. These pieces, referred to as coupons, should be 1.5 to 2 inches wide and 3.5 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.
5. Stick welding: Suggested coupon thickness- ¼” if using ⅛” rod. Suggested rod-AC and DC straight or reverse polarity- first E-7014, second E-6013.
6. MIG welding: Suggested coupon thickness-¼" if using .035 wire and ⅛" if using .023 wire.
7. Oxy-Acetylene: Suggested coupon thickness–⅛" and suggested rod–⅛" mild steel rod.
CLASS 2
1. It is suggested that all welds be of same size and thickness as metal. These pieces are referred to as coupons. The welds can be on one coupon that is about 4”x4” or on individual coupons that are about 2"x4" inch and ¼” thick. Suggested rods for this class of position welds for AC and DC straight or reverse polarity is, first E-6013, second E-7014 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.
CLASSES 3 and 4
1. All welds should be cleaned and protected from rust with paint or light oil. Plans are to be complete enough that if they were given to a welding shop, the item could be made without further instructions. Bill of materials should include a cost for all items used including steel, electrodes, paint, wheels, etc.
