Fibonacci-project: Science in Primary and Pre-School

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!
