How to Make a Paper Model of an Iceberg
Whether for a project on sea travel, the Titanic or icebergs specifically, crafting a 3-dimensional model of an iceberg can help students to absorb and understand the structure of the natural phenomenon. Students can work in teams to build large models, or individually to build smaller paper replicas of the icebergs. Transforming paper into paper mache will create a sturdy and easily molded medium for crafting the iceberg model.

Step 1
Mix 3/4 of a cup of glue with a 1/4 cup of water and tear newspaper into inch-wide strips, approximately 6 inches long.
Step 2
Crumple and fold a piece of cardboard into a pyramid shaped, iceberg base.
Step 3
Dip the newspaper strips into the paper mache mixture and layer on top of the cardboard to coat. Allow to dry completely after every four layers of newspaper you apply before adding more layers.
Step 4
Create a jagged, pyramid shaped mound by applying the paper mache. The overall shape will be triangular; however, the surface of an iceberg is not smooth. Don't be afraid to create smaller, jagged mounds on the overall pyramid shape.
Step 5
Tear narrow strips of white computer paper for the final coat, which can make painting the whitish-blue iceberg easier than painting over black and white newspaper. Dip the strips into the paper mache mixture and cover the iceberg shape entirely.
Step 6
Allow to dry completely before painting. Mix blues and whites together and paint the entire structure with these colors.
Titanic Science – Make an Iceberg
The Titanic famously sank on the 14th April 1912 in the North Atlantic Ocean after colliding with an iceberg.
This activity models how an iceberg sits in the ocean and explains one of the reasons why the iceberg that collided with Titanic wasn’t spotted until it was too late!
Materials
Balloon
Water
Ruler
Water filled container
Instructions
- Fill a balloon with water, fasten the end and leave in a freezer until frozen.
- Once frozen, carefully cut away the balloon and discard.
- Place the iceberg into your container of water.
- Measure how much of the iceberg is above and below the water.
Why does this happen?
Did you know around 90% of an iceberg is under water? Is this the same for your iceberg?
So much of an iceberg is under water because water expands as it freezes, meaning the ice is less dense than the surrounding water.
Sea water, because it is salty, is more dense than fresh water meaning that the ice floats slightly higher in sea water than in our experiment.
Extension tasks
How could you work out how much water is displaced by the balloon?
The iceberg that hit the Titanic was formed from fresh water, but what do you think would be different if you made your iceberg using salty water?
