As youth development educators, we are always trying to find new ways to incorporate more “teachable moments” into our lessons to broaden the learning experience of our students. In addition, we are always trying to integrate science related activities (such as archery) back to S.T.E.M. This article does just that. It uses a common building construction technique, the 3-4-5- rule of making something square, and relates it back to the topic at hand, in this case archery, and then highlights the underlying mathematics principle. I’d like to thank Dr. Mike Lindstrom, a Minnesota educator and S.T.E.M. promoter for the technical explanation of the Pythagorean Theorem.
Construction projects often need to have precise 90 degree or “square” angles. But often the available tools (such as a carpenter’s square) are simply too small to guarantee the accuracy needed for large projects such as laying out the foundation of a house; therefore carpenters, concrete framers, (and archery instructors) will often employ a 3-4-5 triangle technique to ensure accurate 90 degree angles.
Using The Pythagorean Theorem In Theory
The technique simply requires that a person create a triangle in the corner of the lines that are to be square (90 degrees) to each other. The triangle must have one side (leg) that is 3 feet long, a second side that is 4 feet long and a third side that is 5 feet long. Any triangle with sides of 3, 4 and 5 feet will have a 90 degree angle opposite the 5 foot side. If a larger triangle is needed to increase accuracy of very large structures, any multiple of 3-4-5 could be used (such as a 6-8-10 foot triangle or a 9-12-15 foot triangle).
In Geometry, a well known method of constructing a right angle is to employ the Pythagorean Theorem. The mathematician, Pythagoras, discovered a relationship between the sides of any right triangle that is now known as the Pythagorean Theorem; he proved that the square of the longest side (the hypotenuse) is equal to the sum of the squares of the remaining two sides. This is often expressed as the following equation A2 + B2 = C2. (M. Lindstrom, 2007)
Using The Pythagorean Theorem In Practice
The purpose of this calculation is to layout a shooting range in a perfect right angle. A pre-marked 100-foot rope or 100 foot tape measure are tools for this purpose. Leg A is the yardage line marker, Leg B is the shooting line, and Leg is the hypotenuse. Ideally, Leg C would not exceed the overall length of the measuring tool. Use any one of the trio combinations below in laying out your range. Please note this word of caution, for large archery ranges not set up with this precision, it is easy to make it out of square by making simple measurements. That inaccuracy could result in giving one archer an advantage over another, if the targets are at differing distances from the shooting line.

Dear Dr. Wells, I admire your work to find the happy environmentally friendly balance of natural ecosystems within golf courses. We have found many supporters who wish to reinvent the abandoned , privately -owned West End golf course on Newberry Road in Alachua County, and are reaching out to our County government for their support as well. The golf course was the core of our West End Village neighborhood ; we have a dream to revitalize it. Looking forward to contacting you at a later time! Thank you.

Hi Laura, Thanks for your comment! I missed it earlier, I apologize. Please feel free to quote me and reach out if you have any questions. Several of our golf courses have become certified with Audubon International for their conservation efforts!

I am a huge fan of Greenspaces/ Golf Courses. I love the statement you make underlining the importance of golfcourse superintendents as “stewards of the land. “May I please quote you ? I’m writing our commissioners to help save an abandoned for sale golf course! I love seeing deer, red tailed hawks, Sandhill Cranes on this former course. I’ve also seen a pair of pileated woodpeckers, a flock of egrets, and bluebirds.

Hi Chris, Yes, these are "Florida-Friendly" plants, meaning they are low impact, environmentally friendly, use less water and reduce pollutant loading to Florida waters. Learn more here: https://ffl.ifas.ufl.edu/ Thanks! Bonnie
July 1, 2021
Hello, I just want to clarify... Under "Florida Friendly" cloumn, are you saying the plants do well in the Florida environment OR the plants are dangerous because of the ability to spread and damage the environment like Kudzu in Georgia? I live in Boca Raton, in Palm Beach County, which I believe is Zone 10.

Please, please, please add the FL native climbing aster! (Symphyotrichum carolinianum) The incredible explosion of fragrant purple flowers arrives in November & December, at a point when many other FL wildflowers are fading. To me, the flowers smell like sweet, warm sugar cookies! It's always loaded with pollinators too... Perfect for wetter soils - along the edges of ponds, swales, etc. Thanks, Frank Galdo - Program Coordinator, Florida-Friendly Landscaping, UF/IFAS Extension Pasco County Pics & info: https://flawildflowers.org/flower-friday-symphyotrichum-carolinianum/ http://hawthornhillwildflowers.blogspot.com/2009/11/climbing-aster-symphyotrichum.html https://twitter.com/PascoExt/status/1243217796705763329

Thanks for your comments! There are so many math and physics principles practiced and demonstrated in archery! If an instructor can remember to point them out while the kids are on the range, he or she can really reinforce what is taught in the classroom. All the instructor has to do, is find the appropriate teachable moment and take advantage of it. gus

This is a great use of math an angles to help improve your archery shooting range. When teaching a beginner having them line up a 90 degree angle will be helpful for them to take the same stance each time. Thank you

Hey Steven! Thanks for your comment. I suggest you get into hunting with a multi-tiered approach, making sure you are comfortable in the woods, you know the laws and regulations of what you plan on hunting, and starting small - with small game that is. Hunting, which includes dispatching small game takes the same skills as hunting large game but with less input and intensity. If you can successfully bag your first raccoon (for example) and process it all the way to the table, you'll be well on your way to hunting larger game as you gain experience. If you haven't taken it, or done it lately, enroll in your local Hunter Safety class by your state game division. They can help. Go out into the woods and scout around. Go to the range and perfect your skills. All these things will not only prepare you for hunting, but will help you decide IF and how you want to go ahead. I hope that helps! - gus

This is a great article Bonnie. Thank you very much for taking the time to visit the courses and talk to the superintendents. I am sure that you were pleased with the knowledge and effort they use daily to be stewards of the environment. Many are BMP Certified but we need more to get this certification and implement new programs to make the best agronomic and environmental decisions on a daily basis.

The counties currently involved in the FL Horseshoe Crab Watch Program are Franklin, Taylor, Dixie, Levy, Hernando, Pinellas, Manatee, Martin, Indian River, Brevard, Volusia, and Nassau. There are some counties that will be incorporated in the future including those in Southwest Florida (and Collier county). Here on the East Coast of Florida we see horseshoe crabs nesting between December-May depending on where you are. On the Gulf Coast of Florida they see them nesting in the spring and fall (Feb-May and Aug-Oct). It's unknown what the nesting time is in southwest Florida. If you ever do see horseshoe crabs please report them to the FWC Wildlife Hotline for horseshoe crabs at this link: https://myfwc.com/research/saltwater/crustaceans/horseshoe-crabs/ (click on Report Your Nesting Horseshoe Crab Sighting). You can also download the free FWC Reporter App and report sightings through your mobile device (https://myfwc.com/news/all-news/sighting-app/).
