Wind speed

The day started out beautifully looking like another early Spring day but it all changed rather quickly so we took advantage of it and did a wind speed experiment – it was great fun.

We printed off a protractor from here then glued it to cardboard, attached a ping pong ball with cotton (as shown in this experiment worksheet) and measured the angle our string got to. Ours hit 10 degrees, which converted to more than 60 kph.

Using the Beaufort wind scale chart, we discovered the wind was blowing GALE FORCE .

Miss 7 was very excited (probably a result of the wind!) and thought she would practice giving a weather report on the wind to her grandparents later.

    I stumbled upon your site and was excited to find a fellow Australian homeschool blogger who lives on a rural property:)
