Once again there is not a lot of material that would be applicable to my classes. Most of the resources are intended for k-12, and do not include any vocational ed.
I did manage to find several pages which could be incorporated into portions of a class.
An architecture class could use some of the materials on green roofs in their discussion of new building methods. Both Mechanical and architectural classes could use activities on the strength of shapes. In the mechanical design class it would be good to have students look at different inventors, and their inventions, they could then evaluate what made the inventions different, and how they worked. The site also gives a good handbook, on the process of protecting and marketing inventions.
