Geospatial
STEM Geospatial is a diverse category that includes a variety of exhibits 4‑H'ers can get involved in. Through participation in this category 4‑H'ers will gain more knowledge about Nebraska's rich history and diverse geography. Take close note of the rules to ensure your exhibit qualifies.
Rules
Must also follow General Set Rules
H880001 - Poster (SF277) - Create a poster (not to exceed 14 inches x 22 inches) communicating a GPS theme such as How GPS or GIS works, Careers that use GPS or GIS, How to use GPS, What is GIS, GPS or GIS in Agriculture, Precision Agriculture, or a geospatial topic of interest.
H880002 - 4‑H Favorite Places or Historical Site Poster (SF277) - The 4‑H exhibitor identifies a favorite place or historical site (including grave sites) in Nebraska. Exhibit should include latitude and longitude, digital picture, and local area map. Poster size should not exceed 14” X 22”.
H880003 - GPS Notebook (SF300) - Keep a log of at least 5 places visited using a GPS enabled device. At least one site should be from a community other than where you live. For each site, record the latitude, longitude and elevation. Also include a description of the site, a paragraph explaining what was interesting about the site or finding it. Photos of each site and/or cache are optional but encouraged.
H880004 - Geocache (SF301) - Assemble a themed geocache (physical geocache is REQUIRED with exhibit). Each geocache should be a water-tight container. It should include a log book and pencil for finders to log their visits and may include small trinket, geo-coins, etc. for the finders to trade. Documentation should include a title, teaser description and the geographic coordinates of intended placement. Register the site at geocaching.com, include a print-out of its registry. The entry may include a photograph of the cache in its intended hiding place. Register the site at geocaching.com following the Nebraska State Fair.
H880005 - Agriculture Precision Mapping (SF302) -
4‑H members will assemble a 8.5” X 11” three- ring notebook that will include a minimum of 2 digital copies of various data layers that can be used in precision agriculture to identify spatial patterns and/or correlations (printed copies of websites were applications can be purchased is acceptable) A report of how the analysis of the various data will be used to make a management decision.
H880007 - GIS Thematic Map (SF302) - Using any GIS software, create a thematic. Thematic maps can utilize any subject of interest to the 4‑H member. Example map would be Amelia Earhart’s or Sir Francis Drake’s voyage population density maps, water usage maps or 4‑H project in Nebraska. Create GIS Map using data from books, and or internet. Use reliable data, (U.S. Center or U.S. Census Bureau etc.) Map any size from 8.5” x 11” up to 36” x 24”, which should include Title, Base Map, Neat Line, North Arrow, and Legend. Identify the source of your information on the back of the map.
H880008 – Virtual Geocache (SF301) - Keep a log of at least 5 places visited using a virtual geocache platform. At least one site should be from a community other than where you live. For each site, record the latitude, longitude, and elevation. Also include a description of the site, a paragraph explaining what was interesting about the site or finding it. Photos of each site and/or cache are optional but encouraged.
Physics / Power of Wind
All entries must be pre-entered on a General Entry Form at the York County Extension Office by the first Friday of July. All Exhibits will be judged on Wednesday of fair week in Ag Hall. Entries must receive a Purple ribbon at county fair and be selected to advance to State Fair.
This category provides 4‑H member a way to present their ideas about renewable energy resources. Through participation in this category 4‑H member will learn more about physics, friction, energy, and elasticity. In addition, participants will make a display to go along with their findings. For more resources and materials in this category refer to the resource section at the bottom of the page. For help getting started with this project contact your county 4‑H office.

H900001 - Create and Compare Energy Resources Poster (SF277) - Poster should explore 2 alternative/renewable energy resources. Compare and contrast the 2 resources including two of the following information: amount of energy created, costs of production, usability of the energy, pros/cons of environmental impacts, etc. Posters can be any size up to 28” by 22.”
H900002 - Experiment Notebook (SF277) - Notebook will explore the scientific method involving alternative/renewable energy sources. Information required.
1.) Hypothesis
2.) Research
3.) Experiment
4.) Measure
5.) Report or Redefine Hypothesis.
H900003 - Solar as Energy Display (SF277) - Item should be the original design of the 4‑Her. Include the item, or a picture if item is in excess of 6 feet tall or 2 feet X 2 feet. Include a notebook of why the item was designed and how it harnesses the power of the sun. Examples include solar ovens, solar panels, etc.
H900004 - Water as Energy Display (SF277) - Item should be the original design of the 4‑H member. Include the item, or a picture if item is in excess of 6 feet tall or 2 feet X 2 feet. Include a notebook of why the item was designed and how it harnesses the power of water.
H900005 - Wind as Energy Display (SF277) - Item should be the original design of the 4‑H member. Include the item, or a picture if item is in excess of 6 feet tall or 2 feet X 2 feet. Include a notebook of why the item was designed and how it harnesses the power of wind.
H90006 - Other Nebraska Alternative Energy (SF277) - Notebook should explore Nebraskan alternative energy source besides wind, water, and solar power. Include information on type of power chosen, infrastructure for distribution, what resources are needed to create this alternative resource, cost of production, and potential uses of bio-products. Examples include geothermal, biomass, ethanol, bio-diesel, methane reactors, etc.
