How to play Anatomy of a cod

Anatomy of a cod is an interactive simulation.

During this interactive experience, you will dissect two cod fish (one spawning, one not spawning) and record your findings in the data sheet.

The experience is broken down into four main sections which can be completed in any order. They are:

Rotate the cod in 3D
Measure the cod
Weigh the cod
Explore the inside of the cod

Before you begin:

You can use an internet browser on a computer or tablet to dissect the cod and record your findings.

You will dissect two cod caught in different reproductive phases (spawning and not-spawning).

Each section requires you to complete a task and record the information on the Data Sheet.
