Setting the stage

We began by reading the story of the wind and sun 
.

After a brief talk about the history of the wind and sun: we started to think how
we could measure the wind and we then decided to build an instrument for measuring wind:an anemometer.

Let's build an anemometer!

An anemometer is a device that measures the speed at which the wind blows. As such, it is one of the most important instruments in a weather station. The device we build a model of a real anemometer that will give us an approximation of how fast the wind is blowing.

First we cut the rim of the plastic cup to make it lighter. Then we painted the outside of one of the cups with a felt pen.

 

We crossed the cardboard strips so they make a plus(+) sign. and stapled them together

 We used a ruler and a pencil and drew lines from the outside corners of where the cardboard strips came together to the opposite corners. Where the pencil lines crossed we found the exact middle of the cross.

We pushed a drawing pin through the centre of the cardboard and then we attached the cardboard cross with the cups on it to the eraser point of a pencil.

 

We made sure the cardboard was spinning around freely on the pin by blowing on it.

The testing

We went to our playground and each group took thier anemometer. They  placed it in a
open space away from any walls. For a minute we counted the number of laps that our
anemometer turned. It was very funny!

Greenwave activities at EB1 Sofia de Carvalho, Algés

 

 All groups are building an anemometerto be able to measure the speed of the wind.

 

Making a cross of cardboard strips and staple them together.One cup is coloured on the outside with paint.

A drawing pin is pushed through the centre of the cardboard and  the cardboard cross with the cups on it are attached to the eraser point of the pencil.

It is ready...and it works beautifully !

 Now all the anemometertos are ready to be used outside
