How to Make a Model of the Brain Using Styrofoam

Updated April 17, 2017

Making a model of a brain out of styrofoam is simple to do, fun and educational. All it takes is a block of styrofoam, some markers, a knife and a little patience.

Cut a block of styrofoam evenly in half (if you want to cut out the shape of the brain looking from the top down, you can do that first).

Delineate the different sections of the brain using coloured markers. Draw carefully as these will be your guidelines for cutting into the styrofoam.

Cut along the marker lines to show the contours of the brain.

Finish with fine grit sandpaper and seal with acrylic paint if desired.

Indicate various parts of the brain using tabs on stickpins or paint the sections accordingly; e.g., frontal lobe, cerebellum. Utilise diagrams from a book or the Internet for reference.


A dull tip serrated knife works best and is the safest when carving into the styrofoam. As always, handle any knife properly and safely.
