Spend time outside and teach the children to identify flowers, bugs, trees and things. Talk about how we breath in the oxygen that trees give off, learn the cycles of life and how nature works together. When you plant your garden, explain how things grew in the garden of Eden, and after sin man has to work hard to grow his food. In other words, make life an object lesson.
Making Sabbath special is important and I think its good to have a set Friday menu & tradition, like fruit salad in summer and soup in winter with special Sabbath candles. Growing up, our house was always clean and we had our baths before sundown. I still remember the smell of pine sol and dust spray.
Service is also important. They should learn early to visit the elderly, take cookies to someone, sing in nursing homes, etc.
