The wisest and noblest teacher is nature itself.
- Leonardo Da Vinci, Codex Atlanticus
The goal of science education is to help students understand the world they live in, specifically recognizing that we, humans, are an intrinsic part of nature, not separate from it.[1] Biomimicry serves as a powerful impetus for this realization, introducing students to the intricate, time-tested systems of the natural world and inspiring them to develop solutions to real world problems after nature's brilliant efficiency and sustainability. By making the essential yet invisible processes of nature visible, this learning experience empowers students to better understand the natural world and their place within it.
This fourth-quarter biology unit on enables biology students to apply ecological concepts toward enhancing the environmental resilience of Mill River in New Haven, CT. Students demonstrate their learning through a public showcase of nature-inspired projects presented to peers, faculty, and community members, cultivating active problem-solving skills and local environmental stewardship.
What is Biomimicry?
Biomimicry—derived from bios (life) and mimic (imitate)—is the art and science of solving human challenges by emulating nature’s functional systems and processes.[2] It differs fundamentally from related bio-inspired concepts:
- Biomorphic design imitates natural forms without replicating function (e.g., a flower-shaped birdbath).
- Bio-utilization directly uses or harvests biological material (e.g., using algae for energy or fungi for bioremediation).
- Biophilia reflects an innate connection to nature (e.g., cultivating gardens or green walls to enhance well-being).[3]
Biomimicry is rooted in the core principle that life creates conditions conducive to life.[4] The practice relies on three essential elements: ethos, (re)connect, and emulate. Ethos ensures designs actively restore and sustain ecosystems through regenerative practices like localized energy use and material circularity. (Re)connect challenges the misconception that humans exist separate from or superior to nature, grounding us back in the natural world. Finally, emulate invites us to learn from nature’s time-tested designs to innovate sustainably.[5] Popularized by Janine Benyus in her seminal 1997 book Biomimicry: Innovation Inspired by Nature, this framework positions nature as a model, mentor, and measure[6] or “3Ms”.

Figure 1 shows the interconnectedness of the '3Ms' of biomimicry, highlighting how nature serves as a model for developing innovative solutions to human problems. Consequently, nature is respected as a mentor—shifting our focus toward learning from nature rather than merely extracting from it. Finally, nature acts as a measure, utilizing 3.8 billion years of evolutionary refinement and ecological wisdom to establish the ultimate standard for sustainability.
Figure 2 illustrates the six core Life's Principles in biomimicry, which operate under the overarching rule that life creates conditions conducive to life. There are 27 principles, but the primary six are: evolving to survive, adapting to changing conditions, being locally attuned and responsive, integrating development with growth, being resourceful with material and energy, and using life-friendly chemistry. These principles are shaped by Earth’s operating conditions, such as sunlight, water, gravity, dynamic equilibrium, limits and boundaries, and cyclic processes. These will be the standard for any biomimicry design.
Figure 3 illustrates the Biomimicry Thinking process. Starting at the designated dot, the process begins with discovering, then moves iteratively through scoping and creating before concluding with evaluating. Just like in scientific inquiry, Biomimicry Thinking is a non-linear process: ideas continuously alternate between scoping and creating to refine concepts according to nature’s functions, ultimately ensuring the design aligns with Life’s Principles during evaluation. Figure 4 further demonstrates this design framework, showing how the process spirals inward from broad context to specialized innovation.
A Brief History of Biomimicry
Although formalized recently, biomimicry is an ancient discipline. Its roots trace back to approximately 547- 444 BCE, when Chinese inventor Lu Ban (from his wife Yun’s idea), created the umbrella after observing lotus leaves shielding children from rain.[7] Centuries later came key figures like Leonardo da Vinci (1452-1519) and Alessandro Volta (1745-1827). Da Vinci’s flight studies directly influenced Orville and Wilbur Wright’s research into bird aerodynamics, ultimately leading to modern aviation—a term derived from avis, the Latin word for bird.[8] Meanwhile, Volta revolutionized energy storage by investigating torpedo fish and electric eels. Inspired by their specialized electrocytes and dual-pole configuration, Volta stacked alternating zinc and silver discs with brine-soaked dividers to create the voltaic pile—the world’s first continuous-current battery.[9] The electric eel’s ability to chemically produce and store electricity inspired Volta’s understanding of a continuous electric current. Volta mimicked how eels pair a positive pole (head) with a negative pole (tail) to configure his synthetic sustained voltage generating discs.[10] Recognizing the novelty of his creation, Volta even proposed styling the battery like an electric eel to enhance its flair during public demonstrations across Europe.[11]
The importance of aviation and electrical batteries in the modern world can hardly be overstated. Together, these technologies have expanded human exploration from our own planet to outer space, underpinning innovations such as spacecraft, satellites, telescopes, and space probes. It is difficult to imagine daily life without batteries powering our phones and essential electronics. Beyond immediate convenience, greater public awareness is needed regarding how space science drives breakthroughs in medicine, agriculture, and other critical technologies.[12] Ultimately, space exploration fosters a deeper understanding of human interconnectedness—reminding us that across all cultures, nationalities, and backgrounds, we are united with one another and with our shared planet. As astronaut Mae Jemison famously noted following her mission on the Space Shuttle Endeavor:
“When you look at the Earth from space, you realize that our planet is a beautiful, interconnected system. We are all in this together.”[13]
Biomimicry has provided the modern world with a wide range of innovations, spanning simple everyday products to complex architecture. Everyday applications include Velcro inspired by burdock burrs, gecko-based adhesives, waterproof lotus-leaf textiles, and shark skin-inspired Olympic gold-winning swimsuit fabrics. On an industrial scale, natural models have yielded waterless toilets based on tree evapotranspiration, painless needles derived from mosquito proboscises, high-efficiency wind turbines modeled after humpback whale fins, and soft robotics inspired by octopuses. Furthermore, biomimetic design extends to systemic and architectural scales—from using fungi for toxic waste remediation and slime molds for urban transit planning in Japan,[14] to nature-infused architecture like Milan's forest-mimicking Bosco Verticale,[15] and the birdwing-inspired Milwaukee Art Museum.[16]
Janine Benyus, an American biologist, author, and innovation consultant, is widely regarded as the "godmother of modern biomimicry." After publishing her landmark 1997 book, Biomimicry, she ignited a global movement by founding Biomimicry 3.8—a consultancy leveraging 3.8 billion years of evolutionary wisdom to help companies like Nike, General Electric, and Microsoft create sustainable designs. To support educators and practitioners advancing biomimicry practice, she and her team founded the Biomimicry Institute and created AskNature, an open-access repository of bio-inspired solutions. AskNature also offers curriculum materials designed for K- University students that align with national and state standards.[17] The lessons selected for this unit are drawn directly from or adapted from AskNature's collection. Remarkably, Janine Benyus—a pioneer of the modern biomimicry movement—embodies the very principles of 'Mother Nature' that she champions.
Biomimicry and Biology

Although biology forms the foundation of biomimicry, the field extends far beyond biological study alone. Figure 5 highlights this distinction: where traditional biology focuses on learning about nature (e.g., studying a fish and its adaptations), biomimicry centers on learning from nature (e.g., analyzing the structures and functions of a fish to design novel technology). Put simply, biomimicry applies the study of life to solve real-world problems in ways that ultimately sustain life.
Biomimicry and Biodiversity: Rivers as a Biodiversity Hotspot
Biodiversity serves as a living library for biomimicry. Every plant, animal, and microbe represents a unique evolutionary adaptation. When we lose species, we lose potential biological blueprints that could inspire medical breakthroughs, sustainable materials, and ecological systems.[18] Rivers are a biodiversity hotspot, providing critical habitats and migration corridors for thousands of species of fish, birds, insects, amphibians, and aquatic plants. Healthy riverbanks or riparian zones stabilize soil, prevent erosion, and filter pollutants. Rivers support the hydrologic cycle, providing water for drinking, for irrigation, and for transportation in many communities worldwide.[19]
Rivers also offer vital recreational spaces that foster physical, mental, and creative well-being. For me, the Mill River holds personal significance—it is where my dragon-obsessed son, then a preschooler, and I walked along the banks countless times in search of "dragon eggs." Geographically, three major river systems flow through New Haven into Long Island Sound: the Quinnipiac River, Mill River, and West River.[20] I selected Mill River for this unit due to its proximity to Cooperative Arts and Humanities High School, where I teach, as well as the active environmental conservation projects currently underway in and around the watershed.
Rivers were central to Connecticut’s rapid industrialization and urbanization. The Mill River powered Eli Whitney’s historic gun armory in the late 1700s and became New Haven's first public water supply source via Lake Whitney in 1860.[21] As early as the 19th century, Connecticut courts pioneered public water doctrine, extending environmental trust protections and public access rights beyond tidal coasts to inland rivers. By 1900, a majority of the state's population lived in thirteen key cities along major waterways. The state continued leading water conservation efforts by passing the Connecticut Clean Water Act of 1967—five years before the federal Clean Water Act—and establishing the Lower Connecticut River Conservation Zone in 1973, which created an early model for integrating local zoning with state-level environmental mandates.[22]
The Mill River Trail Green Infrastructure Park, currently underway, was designed to connect the East Rock and Fair Haven communities through a dedicated pathway. The park features bioretention areas that divert stormwater runoff from city sewers, along with native plant gardens cultivated to suppress invasive species.[23] Looking to expand public waterfront access, New Haven Mayor Justin Elicker recently presented a plan to add an outdoor pool, playgrounds, sports courts, walking and biking trails, and native plant gardens along 3,000 feet of waterfront property. However, this site—formerly the English Station Power Plant, which operated as a coal- and oil-fired facility from 1929 to 1992—remains heavily contaminated with carcinogens, heavy metals, and other pollutants, requiring extensive remediation before development can begin.[24]
Biomimicry Projects for River Ecosystems
The following are some of the nature-inspired river restoration projects:
- Beaver Dam Analogues (BDAs): Human-made structures that mimic natural beaver dams to restore urban waterway systems.[25]
- Mangrove-Inspired Structures: Frameworks built like interlacing mangrove roots in creeks to regulate water velocity, particularly during flood events.[26]
- Wetland Filtration & Floating Islands: Systems that replicate the root networks of wetland plants to filter water and enhance biodiversity.[27]
- Fish-Inspired Bank Stabilization: Structures modeled after fish scales and fins designed to reduce river erosion, increase riverbank permeability, and foster ecological diversity.[28]
In and around New Haven, specialists are working to harness the natural filtration capacity of oysters.[29] A single oyster can filter up to 50 gallons of water daily, removing excess nutrients and contaminants that cause eutrophication, algal blooms, and oxygen-depleted dead zones. To support coastal protection, artificial reefs made from 3D-printed substrates mimic the fractal structure of natural oyster reefs, which can reduce wave energy by up to 93% and prevent shoreline erosion. Additionally, scientists have developed non-toxic, 3D-printed clay materials that replicate the calcium carbonate composition of real oyster shells, encouraging juvenile oysters (spat) to settle, grow, and thrive.[30]
Teaching Biomimicry
I first encountered biomimicry in 2018, in Susan Huminski's graduate course on sustainable design at Southern Connecticut State University. The concept fascinated me, but its practical power truly clicked years later while teaching science at Wilbur Cross High School (2023–2025). One day, a colleague and I were trying to fix a leaking water filter station. As we worked, I began drawing parallels between the machine's mechanics, the input-output process of a simple coffee maker, and the complex filtration system of the human kidney. Ever since, I see echoes of nature’s designs in the technology around us. This experience inspired me to pursue deeper learning in biomimicry so I can bring these fascinating connections directly into my classroom.
Becoming a fellow with the Yale-New Haven Teachers Institute provided the precise opportunity I had been seeking. Professor Paola Bertucci’s seminar, Making Visible the Invisible, significantly broadened my perspective on implementing three-dimensional (3D) learning under the Next Generation Science Standards (NGSS). Throughout the course, we examined archival materials, illustrations, instruments, and models of nature—spanning constellations, the solar system, insects, and exotic animals to natural and imaginary "monsters," early machineries, the human brain and physiognomy.
I continue to reflect on the immense depth of knowledge gained from Prof. Bertucci’s seminar. Above all, I was deeply moved by the realization that the artifacts we were studying—whether crafted by celebrated scientists or unsung artisans—reflect humanity's enduring quest to make sense of the world, whether for material, social, or political ends. The seminar underscored the irreplaceable value of hands-on, tactile evidence. Touching primary artifacts, engaging with tools like the physiognomy card game, looking through a replica of Galileo’s telescope, and feeling the spark of static electricity from the electrostatic generators made learning truly profound. Moving forward, I am committed to ensuring my students actively investigate tangible evidence and materials whenever possible, rather than relying solely on images on a screen.
Biomimicry thinking and design align well with the NGSS three-dimension (3D) learning in science education.[31] The three dimensions of science learning integrate the disciplinary core ideas (DCI), science and engineering practices (SEP), and cross-cutting concepts (CCC).[32] The four (4) Disciplinary Core Ideas (DCI) for high school biology are: From Molecules to Organisms: Structures and Processes; Ecosystems: Interactions, Energy, and Dynamics (Matter and Energy / Interdependent Relationships), Heredity: Inheritance and Variation of Traits; and Biological Evolution: Unity and Diversity (Natural Selection and Evolution). The eight (8) Science and Engineering Practices (SEP) are asking questions (for science) and defining problems (for engineering); developing and using models; planning and carrying out investigations; analyzing and interpreting data; using mathematics and computational thinking; constructing explanations (for science) and designing solutions (for engineering); engaging in argument from evidence; and obtaining, evaluating, and communicating information. The crosscutting concepts (CCC) span across academic disciplines to help students bridge knowledge. The key concepts are patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change. All these concepts – are crucial in biomimicry thinking and design.
