Update 2020-11: The Adobe Shockwave is no longer supported but I have received requests to access this interactive practice. So now I have made this interative practice available as an executable for Windows.
Click here to download the executable. Remember where you download the file to. After it has finished downloading, double-click on the .exe file to run it. It does not require Internet access to run.
Please email me if you need an executable for MacOS.
