Exciting science stuff to promote higher order thinking.
http://www.smogcity.com/ - Students set parameters for variable and test the effect on a virtual city.
www.pbs.org/wgbh/buildingbig - A simulation activity for physics students. Students solve problems related to a city's needs for various structures such as bridges, domes, skyscrapers, dams, tunnels, etc.
http://whyfiles.larc.nasa.gov/treehouse.html - At first it looks like an elementary site - it is not.
Students search resources and solve a mystery while using critical thinking and problem solving skills. Your students will not want to put this one down. Incredibly rich in its complexity.
