THE WAY THE WIND BLOWS

Today our page out of "The science and history project book" was on the way the wind blows and we also created the third in our tools built to record weather.  The previous tools being the rain gauge and the hygrometer.

The first experiment showed how the weight of a particle affects how far it travels and the effect this has in creating various sand dunes. 

The used a hairdryer as our wind and noted that the smaller particles of the sand went further down the ice cube tray then the larger particles.

 

 

Then we made a simple weather vane and spoke about anemometers and how they are used to measure wind speed. 

 

Our cat thought it was really tasty!!

 

 



The lessons in this book are fantastic and so quick to pull together into a lesson that the kids really look forward to every week.
