Science simulation software that contains everything you would find in a chemistry lab...raw elements, chemicals, equipment. You drag the items onto a work area to teach and/or create simulations such as chemical reactions...chemistry, electricity, math, computing, would be awesome on the SB.
Two brilliant high school chemistry teachers have completely switched the lecture at school/homework at home paradigm. Their students watch the lecture at home as a vodcast (on computer, iPod, or DVD) and do problem sets at school with help from the teachers. Check out the news story from the local TV station. I used to live near Woodland Park...
Math and Science Simulations from the University of Colorado. Can change various parameters to create simulation; can also create different graphs associated with the simulation. Appropriate for middle school and high school.
