SCI Blog

At the Science Center of Iowa, our goal is to be a quality community resource for informal science learning where children, families, school groups and individuals of all ages come to explore science and technology.

To continue the learning outside our building, we bring you the SCI blog! Our knowledgeable staff, along with special guests and local scientists, will give you a behind-the-scenes look at SCI activities, in-depth information about science events and STEM connections in the Des Moines area.

  • The not-so-day-to-day life of a Yellowstone Park Ranger

    Park Ranger Mike Coonan’s “office” is more than 20 million acres of glaciated valleys, pristine forests and, of course, the signature geysers at Yellowstone National Park. We sat down with Mike, a University of Northern Iowa alumnus, to discuss his path to the parks and the upcoming centennial of the National Park Service.

    SCI: How long have you been a park ranger at Yellowstone National Park, and how did you land there?

    MC: I’ve been working at Yellowstone National Park for seven years now. It’s a second career for me. It takes a college degree. I’m a graduate of UNI. Go, Panthers! I had a friend who was a park ranger at Neal Smith National Wildlife Refuge here in Iowa, and she encouraged me to apply for a program called the Youth Conservation Corps, and I also applied for the Yellowstone program. I was offered both jobs, between working in the Upper Peninsula in Michigan or Yellowstone, and I chose Yellowstone. I haven’t looked back.

    SCI: Can you describe the day-to-day life of a park ranger?

    MC: One of the things I love about my job as a park ranger in resource youth education programs is that there is no day to day. Today I’m working at SCI. Other days when I’m in the park, my favorite thing is leading school groups. We like to call Yellowstone the largest laboratory or the largest classroom, being over two million acres and being preserved as the first national park in 1871.

    Of course, I study the geysers and hot springs that make Yellowstone so famous, but also the plants and animals and the landscape, where we can look down a river valley or a glaciated valley. To not see a building or a road or a fence or even a power line is amazing. We can really talk about the plants and animals and also the super-volcano, which is a source of energy in the geysers. We have Earth science, animal science, biology, as well as human history. My favorite thing is to walk and talk in the resource and be able to look at it, touch it, feel it, smell it. We usually don’t allow visitors to taste it.

    SCI: Is there a specific age group of students you like to work with?

    MC: I love my team that I work with because we have different expertise. When it comes to the Pre-K through first grade, yeah, they scare me. I like working with grad students from the University of Texas in microbiology. Working with teens or preteens is my niche. I work with junior-high/high school, sometimes college. I also work with teachers, which is amazing. The diversity is incredible. When my office is outside, those are the good days.

    SCI: What’s the most rewarding part of your job?

    MC: I always say Yellowstone does its job every day when we have kids, students and teachers in the natural resource. We can talk scats and tracks. When they discover that and call you over, it’s their discovery.

    How much they teach me is amazing. We’ll talk about why we can’t pick up the petrified wood or obsidian. You know, the natural resources. To quote a fourth grader, ‘So someone else can discover it.’ I stole that line from that student. I think it’s spot-on. With over four million visitors in the park throughout the year, you can’t take a rock. If everyone took a rock, that would be devastating. We’re facing probably a busier year with the National Park Service turning 100. It’s amazing to have a fourth grader make a discovery and say, ‘Yeah, so the next person can find this arrowhead or piece of petrified wood or this teepee ring.’ Same thing with scat. Hopefully no one is putting that in their pockets, but you never know.

    SCI: Can you talk about the centennial of the National Park Service coming up this summer?

    MC: It’s great, and they’ll be doing other free days on the centennial, which is in August. August 25, give or take a day. It’s amazing that we’re nationwide celebrating our national parks, including our urban parks and historic areas, as well as our iconic parks like Yellowstone. It’s amazing.

    SCI: How many national parks have you visited?

    MC: I don’t really keep track. Since I started working for the park service, I have explored more parks. I seem to enjoy them much more as a fellow park ranger than I ever did as a child.

    I am not ashamed to say I got about seven Junior Ranger certifications last year. I am an official Junior Ranger at several different parks, not just my home park. That’s one of the things I really enjoy about working with the teen program, the Youth Conservation Corps, which was my foot in the door. It’s great to see how 15- to 18-year-olds get so excited about working with the Junior Ranger program. You can’t help but have fun, but you learn more about your park and how you can connect.

    There are incredible programs all over. The Arches in Utah. The National Mall in D.C., which is the Washington Monument. As well as the White House. Our urban parks see a lot of visitors, and they have a lot of incredible programs.

    Our catchphrase is, ‘Find your park,’ and we hope everyone finds a park! It’s on my to-do list to make it to Effigy Mounds here in Iowa. Find your park, get outside and enjoy this incredible system we call our National Park Service.

  • STEM in DSM: Principal Park and the Pythagorean Theorem

    Lines and figures dart from home plate, but they’re not plans for a winning play at Principal Park… They’re plans for every angle of an official baseball field, down to every last angle.

    Casey Scheidel, business/project manager at Iowa Cubs Sports Turf Management, peels away the layers of a proposed baseball and softball complex in Anamosa, Iowa. Each blueprint page reveals a single element of a regulation field: the distance from home plate to the bases, the elevation of the mound, the watering radius of each sprinkler.

    Geometry — and in particular, the Pythagorean Theorem — informs every element of your ballpark experience. Here are a few examples of the geometry of baseball in action:

    • It all starts at home plate. A surveyor determines the latitude and longitude of home plate, and the position of every other element of the field is based on its location. Home plate is 60 feet, 6 inches from the center of the pitcher’s mound.
    • Laser focus. Surveyors and engineers use software and GPS technology to exact the measurements of every point on the field.
    • Sun in your eyes? It’s for the batter’s sake. Major League Baseball stadiums are positioned based on sun angles, so the batter never looks directly into the sun.Pitch perfect. The perfect pitching mound increases in height one inch per foot.
    • Flattening the field can take days. Field elevation can’t change more than a quarter-inch over 25 square feet… And it can take the tractor up to two days to grade it, roll it and grade it again.
    • High-tech homeruns. Surveyors use CAD, computer aided drafting, to map the latitude and longitude of every point on the field, including the location of each fencepost.
    • Geometric grass. The signature crisscrosses, swirls and circles in the turf serve no purpose beyond beautifying the field… But geometry is key in their creation. The I-Cubs’ turf crew carefully lines up its mowers with the foul line and bases — and it can take five days to define a design on the field.

    Experience the angles, lines and symmetry of your everyday world at the ballpark AND at SCI!

    Iowa Cubs opening day is April 7. As you munch on peanuts and Cracker Jacks, imagine the now-invisible lines that helped create your favorite ballpark moments.
