It certainly has been an interesting time to study the weather! The girls learned that hot air rises and cold air goes down. They were able to observe a similar process using warm and cold colored water, which was easier to see. Recording the experiment on the iPads meant it was easy to watch it over again.
After observing the movement of the water, the girls understood that wind is caused when warm air rises and cold air moves in to take its place. To determine the wind direction, each girl made her own wind vane. Then the girls got creative as they worked in pairs to design original wind socks.
They designed and built their wind socks.
The girls used a fan to test their windsocks, making sure they could move freely.
It was especially fun to take the wind vanes and wind socks outside! We used a compass to determine which direction was north so that we could orient the base, then we watched as the wind vanes and wind socks gently turned in the breeze.
