Subject: Growth projects

We are doing growth projects in Algebra II, where students are to find data detailing some kind of growth or decay, for example populations, or disease prevalences. Students then make a scatter plot and have to find equations of best fit using linear, quadratic and exponential functions. They follow this by finding the prediction equations for these graphs, and making predictions for 10 years in the future. My question is two fold. I would like to integrate technology into this project. Although we already use the TI-82 in the classroom, I was wondering if there was a better program to use in a computer lab where the students could create multi-media presentations? I would also like to aide them in finding data on the internet, but have struggled myself in sifting through statistics on the web. For instance, in the last two years, I have been looking for HIV statistics over periods of time, but cannot seem to find the right site. Do you know of links to the type of data that my students need? Sincerely, Josh Yezerski
