Ending Classroom Dissection

Transforming Science Classrooms

We can change the way that kids learn science
Modernizing Science

Animal Use in Science is Normalized

Starting at an early age, students are taught that the only way to learn biology is through the use of animals. Education can become more inclusive, cost-efficient, and beneficial to all through humane methods that eliminate dissection and open up discussions about animal welfare.

Did you know?

When we are taught at an early age that animal research is the standard for how science is conducted, we are desensitized to the cruelty of the practice and accept it as the norm. By teaching humane science, students can think critically about research that affects all of us, and continue to be informed citizens that value what is most effective and most humane.

Since every classroom is different, we don’t recommend specific products, but you can use our humane product catalog to narrow down your search.

Classroom dissection has become ingrained in the way science is taught

Students are able to learn just as effectively without the use of animals in the classroom. Moreover, humane replacements save money, the environment, and the health of students.

Benefits of Using Humane Models for Classroom Dissections

Humane. Cost effective. Environmentally friendly. Smart.

Dissection replacements are effective

When given post lab learning assessments, students who conduct humane dissections do just as well as or better than their peers who do traditional dissections1.

Dissection replacements are chemical free

Specimens preserved with formalin can cause irritation to the eyes, nose, and throat. Preserved specimens smell awful and require extra teacher labor for lab set up and disposal.

Dissection replacements are eco friendly

Many humane dissection tools are reusable year after year while animal specimens are single-use. Many animal specimens are sourced from the wild, causing disruptions to natural habitats.

Dissection replacements can be more cost effective

Many models are less expensive than preserved animal specimens. Some are even available for free.

Make Your Case as a Student to Opt‑Out of Dissection

There are smarter and more humane ways to learn science

Know your rights

Many states and school districts have policies protecting a student’s right to opt out of dissection. Most teachers will allow students to opt out of dissection exercises if they ask.

State the facts

Dissection is inhumane, expensive, and unnecessary for successful learning.

Propose an alternative

There are over 100 different dissection replacement tools on the market. Explore them in our humane product catalog.

Share funding sources

Encourage your teacher to apply for a BioLEAP Classroom Grant if they need funding.

Our mission: change the way science it taught

Our BioLEAP program seeks to make science education more humane by eliminating animal dissection in the classroom and teaching students about ethical replacements for animals used in research.

How We Transform Science Classrooms

BioLEAP Classroom Grant

This grant helps educators fund the use of humane anatomy models in their classrooms to replace animal dissection. Through this grant, teachers are reimbursed up to $1,000 for the purchase of advanced learning tools such as 3D digital models, synthetic specimens, and other innovative products.

Engage with Teachers

By attending conferences across the country, NAVS is able to speak face-to-face with teachers and learn how we can help.

Animal Use in Science: Exploring the 3Rs

BioLEAP offers lesson plans and curriculum on the 3 Rs (Replacement, Reduction, and Refinement) to teach students about important concepts related to the use of animals in research and testing. .

Each year, more students are learning how to think critically about animal research and make informed decisions.
