How Dissections in Science Classrooms Are Evolving

In the corner of a high school biology lab, the familiar scent of formaldehyde once signaled the start of a rite of passage—dissection day. Students gathered around stainless steel trays, scalpels in hand, peering nervously at frogs, fetal pigs, or sheep hearts. This tactile and sometimes squeamish introduction to anatomy has long been a hallmark of science education.

But in today’s classrooms, the scalpel increasingly shares space with the stylus.

As digital tools, ethical debates, and educational equity concerns reshape the way we teach biology, educators are reexamining how students explore the inner workings of life. Should we still rely on the preserved body of a frog to teach anatomy? Or is a pixel-perfect 3D simulation just as effective?

This isn’t a battle of old school vs. new tech. It’s a story of adaptation, innovation, and finding the right blend of engagement and ethics in 21st-century science.

The Power of Hands-On Learning: Why Traditional Dissections Still Matter

There is no substitute for the tactile “aha” moment a student feels when they uncover the complex muscle layers of a fetal pig or locate the heart valves inside a sheep organ. These moments—anchored in real, physical exploration—have helped generations of students make sense of the abstract systems described in textbooks.

Traditional dissection remains an unparalleled method for:

• Exploring the 3D spatial relationships between organs

• Observing variations between specimens (and even within species)

• Building comfort and skill with lab tools, such as scalpels, probes, and forceps

• Engaging kinesthetic learners who thrive through touch and movement

Beyond the curriculum, dissections teach patience, precision, and respect for life. Students experience firsthand how complex and interconnected living organisms truly are.

Yet this method comes with real trade-offs. Specimens can be expensive, messy, and—especially in rural or underfunded schools—logistically difficult to acquire. Ethical objections and growing student concerns around animal welfare also pose challenges, especially in more culturally and socially aware classrooms.

Additionally, many science educators face what some have called a “time famine.” With shrinking lab schedules and jam-packed standards, teachers often struggle to fit in full-scale dissections. Supply chain delays can compound this issue, making “frog day” harder to plan and execute than ever before.

The Rise of Virtual Dissections: Accessibility Meets Innovation

Enter virtual dissection—an increasingly powerful option that reimagines anatomy exploration for the digital age. Platforms like BioDigital Human, Froggipedia, and Dissection Lab 3D offer interactive simulations where students can slice through organs with a tap or drag of a cursor. These tools allow for zoom-ins, 360-degree views, and repeat practice—without the cleanup.

Virtual dissection has transformed science learning in several key ways:

• Accessibility: Any student with a device and internet connection can participate—no lab table required.

• Equity: Students who opt out of animal-based dissection for ethical, cultural, or religious reasons can still fully engage in anatomy study.

• Scalability: Schools can offer dissection experiences to larger groups or repeat them throughout the year without restocking supplies.

• Cost Savings: Over time, software access often costs less than procuring specimens and tools annually.

During the COVID-19 pandemic, these tools became indispensable, giving students the ability to explore anatomy from home. For some districts, the shift to digital stuck—either replacing or supplementing traditional dissection altogether.

Bridging the Gap: Synthetic Models and Hybrid Solutions

But what about the feel of slicing into muscle tissue or locating a hidden organ by touch? That’s where synthetic dissection models are gaining traction. Made from advanced polymers and engineered to mimic the texture and resistance of biological specimens, these reusable models provide a hands-on experience without the ethical concerns.

Although currently more expensive than digital or even preserved specimens, these models offer a promising middle ground. And as demand increases, prices may drop, making them more accessible to public school systems.

Educators are also combining both approaches in innovative ways. For example:

• Pre-lab assignments using digital simulations help students prepare for the real thing with confidence and clarity.

• Post-lab digital explorations allow for review, reinforcement, and deeper conceptual understanding after the physical dissection is complete.

This hybrid model, used in some high schools and many medical programs, offers a compelling mix of tactile engagement and tech-driven reinforcement. It also allows teachers to cater to different learning styles, ensuring broader student success.

Ethical and Educational Considerations in Modern Dissection

As states update science standards and school boards revisit lab requirements, ethical considerations are now baked into curriculum conversations. Many jurisdictions require that students be offered an alternative to animal dissection. Instructors must create inclusive environments where opting out isn’t seen as a moral or academic failure.

Equally important is addressing the digital divide. Not every student has a device capable of rendering high-quality 3D models, especially in lower-income communities. Schools looking to adopt virtual dissection must ensure their technology infrastructure can support it—otherwise, accessibility becomes another barrier.

Educators also emphasize the importance of teaching anatomical respect and scientific empathy, whether students are handling real organs or simulated ones. Dissection—at its best—isn’t about shock or spectacle. It’s about curiosity, connection, and cultivating future scientists.

 New Era of Anatomy Education

Dissections are no longer just about what happens on a tray in the lab—they’re about what happens in the mind of the learner.

Whether wielding a scalpel or swiping on a screen, today’s students have more ways than ever to explore the complex systems that power life. Each method—traditional, virtual, synthetic—offers its own strengths, and the most powerful science programs know how to leverage them all.

By embracing flexibility, honoring ethical diversity, and harnessing technology, educators can reimagine dissection as a dynamic, inclusive, and deeply impactful part of STEAM education. After all, the ultimate goal isn’t just to dissect a frog—it’s to awaken a lifelong fascination with the living world.
