STEM Rockets/Drones
Division 850
See Rules for STEM Projects at https://extension.unl.edu/scotts-bluff-county-4-h-fair-book/static-inside-building/science-technology-engineering-math-stem/.
Entry level rockets, made with PLASTIC FINS and PLASTIC BODY TUBES, are COUNTY ONLY projects.
Scoresheets, forms, contest study materials, and additional resources can be found at https://go.unl.edu/ne4haerospacehttps://go.unl.edu/ne4haerospace.
Rules:
- 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 the exhibit may be identified if the entry tag is separated from the exhibit.
- Rockets must be supported substantially in order to protect the rocket from breakage. Rockets are to be mounted on a base that has dimensions equal to or less than 12" x 12" and the base should be 3/4" thick. No metal bases. If the rocket fins extend beyond the edges of the required base (12" x 12"), 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 side boardssideboards or backdrops to the display. In addition, a used engine or length of dowel pin is to be glued and/or screwed into the board and extended up into the rockets 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 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 and 7) conclusions.
- The flight record should describe the 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 be shown 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. For scoring for the State Fair, only actual launches count, misfires will not count towards 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.
* The skill level of a project is not determined by number of years in project. Skill level is determined by the level listed on the manufacturing 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 of the model. They use motors in ranges over “G” power and/or weigh more than laws and regulations allow for unrestricted model rockets. These rockets are NOT appropriate for 4-H projects and will be disqualified.
State Fair Special Recognition:
Premier 4-H Science Award is available in this area. Please visit this site for more details https://4h.unl.edu/4-h-fairbook-nebraska-state-fair/contests/premier-science-award/.
