Easy to do, easy to understand, inexpensive project and activities illustrating the basic solar energy principle of all solar architecture and heating: sunlight=heat, shade=cool. Draws on materials in Michael J. Daley's AT HOME WITH THE SUN solar project book. Includes simple facts about the sun's path in the sky through the seasons, ancient Greek solar home design, a connect the dots activity, and a model house project using a doughnut or shoe box demonstrating summer sun and winter sun.
