This is an interactive simulation of a pretty common lab that teaches the topic of density by demonstrating the difference between "new" pennies (made from Zinc) and "old" pennies (made from Copper).
It follows the process from measurement, through data crunching to graphing, and analysis.
Students run through the lab in its entirety.
The file can be projected as a class activity but if you have access to a computer lab, it's ideally suited for students to run the simulation on their own.
Once properly protected (instructions on how to do that are in a separate file in my store called, "Kiosk Instructions".), double-clicking the file icon, starts the kiosk... Students run through the simulation, calling the teacher over over only when;
1. They run into a technical glitch...
2. They are confused on the content...
3. They're done!
As with all my kiosks, #3 is easy and particularly fun for me. I insert a picture of my family on the last slide. My instructions are phrases like, "Go show me the picture of my son!" You can also easily substitute your own pics.
Touch screens are particularly fun with these kiosks.
