Building and Construction Science Fair Project

Skyscrapers and Wind Forces

Skyscrapers and Wind Forces | Science Fair Projects | STEM Projects
Skyscrapers have to deal with increasing vertical gravitational forces as well as horizontal forces resulting from wind. To find out how the shape of a skyscraper affects its ability to withstand wind, build model skyscrapers with different shapes and test them in a wind tunnel.


The hypothesis is that a skyscraper with a circular cross-section will be able to withstand the greatest force of wind.

Method & Materials

You will build a wind tunnel and model skyscrapers with different shapes. Then, you will gradually increase the wind speed and observe the model buildings to determine which shape can withstand the greatest force of wind.
You will need an industrial fan, 4 pieces of polystyrene foam, 4 pieces of plywood, a hammer, nails, a ruler, a pen-knife, and 4 boxes of playdough.


It was observed that the model building with a circular cross-section withstood the greatest force of wind, while the model building with a rectangular cross-section was the least resistant to wind.

Why do this project?

This science project is interesting because it shows how the shape of a skyscraper affects its ability to withstand wind.

Also Consider

Experiment variations include building model buildings with denser materials such as wood, and testing to see if the type of surface or paintwork on a building will affect its resistance to wind forces.
