Ms. Roberson’s first grade delves into a STEM unit on bats

Article by: Jocelyn Miller

Ask an average first-grader about bats and they might cringe. Ask a first-grader in Katy Roberson’s class at West Fannin Elementary and you will walk away an expert. After reading the book, Stella Luna by Janell Cannon, Reid Summers shared with his classmates details about observing bats around his home. 

The class became instantly intrigued. Ms. Roberson took this opportunity, and immediately sought out information, experts, and volunteers, to design a year-long STEM (Science Technology Engineering and Mathematics) unit centered around bats native to Fannin County.

Students began their project by inviting a guest speaker, Georgia Master Naturalist Jocelyn Miller, to discuss the 16 species of Georgia bats, their habitats, and foraging behaviors. Students later conducted a mock research study where they measured and weighed different “bat species” then recorded data similar to how an actual biologist would monitor bat populations in the field. As the unit continued, students built upon their knowledge and did additional research in small groups where children produced a portfolio demonstrating what they learned. Along the way, students realized that bat habitat and conservation was a serious concern.

 

Bats in Georgia and around the United States have seen a
significant and steady decline in their populations due largely to pesticide use, water quality, and white-nose syndrome. White-nose syndrome has killed between 5.7 to 6.7 million bats in the U.S. since the mid-1990s when the disease was first discovered. The students in Ms. Roberson’s class wanted to do something about it. Their solution was to erect a bat house on the campus of West Fannin.

 

 

 

 

 

Using guidelines from Bat Conservation International along with the help of Trent Summers and Chad Anderson, students were able to design and build a large three-chambered bat house capable of housing up to 500 bats. Once the house was constructed, students weatherized and painted the house. Emma Dills, a student in the class, said her favorite part was painting the bat house. Bat houses must stay dry and warm (around 100 degrees Fahrenheit). Students chose a dark color to help raise the internal temperature of the house. The bat house was installed over spring break with the help of Chris Rogers. The students chose to locate the house near the school apple orchard as a form of pest management. According to first-grader Lilli Potzauf, “Bats eat mosquitoes and are natural bug controllers.”

 

The long-term goal of this passionate group of first-graders is not only to improve the habitat for bats at West Fannin but also to encourage members of the community to follow suit. They are planning a bat garden with native plants that will attract nighttime insects and hope to cultivate and sell those plants to parents and members of the community. They are also working to acquire funds in order to install a camera in the bat house to allow streaming video of the bats’ daytime activities. First-grader Carson Callihan summed up the project perfectly: “We need to help the bats because a lot of them are dying and we need them to eat mosquitoes.” The complex relationship between ourselves and the local ecosystem is difficult to understand at any age, but these first-graders are already making a difference that will have a lasting impact on our community for years to come.
