Wind Power

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?

Materially Speaking

In Science with Mrs.W this term, the children been learning about fabrics.

We've found out that materials/fabrics are made of fibres.
Some fibres are natural, such as wool, cotton and flax.
(See our learning about flax here)

Some fibres are man-made, such as nylon.
Fibres can be spun into yarns, and yarns can be woven or knitted into fabric.

Sheep's wool can be spun into yarn.

We explored a range of fabrics, looking at properties, and sorting into groups.

We did some investigations.

Some fabrics are easier to rip than others.

Some are more absorbent - that means that they soak up liquid.

Over the next few weeks we will be using our learning as we work on a technology challenge!
