Since I will need a new roof and a new furnace in about five years, I wonder when it will be ready to heat my home. I like the idea but I am also wondering about its texture. Any hints?

Reading all of the above makes me realize my daughter was right to question the primary, science curriculum in B.C. Why do we continue to teach about matter (solids, liquids and gasses)? Is there an easier way to explain the transfer of energy? Must I continue to boil water to make vapour and then freeze water to make ice?

Somehow, it all seems insignificant. Perhaps the process is far more important than the content. Thats my best hope.
