How big is a wind turbine blade?

 

How big is a wind turbine blade? Today in class we turned into real researchers!

First, we learned about the lengths and widths of blades from different wind turbines – from the small ones to the truly enormous. We wondered how big they need to be to produce energy from the wind.

Then we headed to the school hallway to check these dimensions in practice. We measured, calculated, compared, and worked together in groups. It turned out that some turbine blades are so long that… our hallway was too short to measure them completely!

It was great fun combined with learning – these hands-on activities showed us how huge the parts of wind turbines can be and how important accurate measurements are.

Learning by doing – that’s what we like best!
