Topographic Maps: Constructing a 3D Model

Create a 3D model from a 2D map!

You’ll need:
A simple contour map – 2 copies (you can draw one yourself if you can’t easily find a suitable one)
Fun foam*
Scissors
Glue

Procedure:
1. Set aside one copy of the map to use as a reference.
2. On your “cutting map”, cut along the outer-most contour line. Trace around this piece on a piece of foam. Cut out this piece of foam.

3. On your “cutting map”, cut along the next contour line. Trace around this piece on a piece of foam and cut it out. Use your “reference map” to place it in the appropriate place on the bottom layer. Glue it in place.
4. Continue the process of cutting, tracing, cutting, positioning and glueing until you have completed all the contour lines on your map.

*You could also use corrugated cardboard or styrofoam. Fun foam is great because it’s very easy to cut with regular scissors (not the case with cardboard, you’re likely to need something a bit more powerful).
