What materials would keep my house just the right temperature?

Earlier in the year we experimented with different types of materials including fur, diapers, sod, newspaper and cardboard and we proved with data and graphs the best materials for building a house. We related how animals survived in the wild with extreme cold and hot temperatures. This was another fantastic activity. Tried to use Vimeo with no luck today so I just played with some of Splice’s features that I never have time for during the school week.
