Big Fish, Little Fish

NISE Network product
Big Fish, Little Fish is a cart demo that can also be used as a classroom activity that focuses on what biomagnification is and how it happens in our ecosystems. Visitors will see a short visual demonstration followed by an interactive game.


Big Idea

Big Fish, Little Fish is a program aimed at educating the public about how biomagnification occurs and its effects on certain ecosystems. They will learn about how the biomagnification of certain chemicals such as DDT and mercury have created significant environmental issues and discuss environmental concerns related to potential biomagnification of nanoparticles.

Learning Goals

Recognize what biomagnification is and how it happens.

Understand the difference between biomagnification and bioaccumulation.

Learn about past examples of chemicals that biomagnified in the ecosystem.

Understand how nanoparticles have the potential to biomagnify and the impacts they may have.

Nano Content Map
Nanotechnologies—and their costs, utility, risks, and benefits—are closely interconnected with society and with our values.
