Hello Linda and Greetings from Scotland!
This is a great discussion and I just had to pitch in ....
1) If it's any help the Swedish I Ur Och Skur schools and pre-schools have the following policy re winter temperatures
"I Ur och Skur schools have an indoor place. If the weather is really atrocious or the temperature falls below -10°C then the children will spend up to three hours inside at some point between 8.30am and 2.30pm which is the standard day." It's worth remembering that most Swedish outdoor schools are in the near vicinity of woodland which provides more shelter. Also many have outdoor shelters and dens in the forests too.
2) If you visit the resources section of my website, scroll down and click on the "Winter Wonderland" link. You can freely download the activity pack I created a wee while ago.
Best wishes and enjoy the cold weather. This our second day of frost! No snow yet!
Wow, thanks to you all! Less than 24 hours after I posted this, I have a ton of great resources and ideas. It feels like Christmas! I'll definitely incorporate the idea of using areas with visitor centers -- an easy way to transition from inside to out. And it hadn't occurred to me to build a campfire. I know that would be a hit. I appreciate all the suggestions for Web sites and hearing about "The Elements." I can't wait to dive into them all. You all are making my job of starting this club a lot easier. Many thanks!
