Following on from the science investigation into fabrics,
the students were given a technology challenge to design a wind cart that could travel 2 metres powered only by wind.
The science work on fabrics would help when making decisions about the best sails to use!
First there were some key concepts to explore:
The design brief:
Building the wind carts:
The final models:
And now watch the movie of the wind carts in action!
Have you ever made a wind cart?
What would you use if you were making a wind cart to ride on?
