A simple drag & drop introduction
Just double click to unzip.Open the folder and double click on the " hess law drag & drop.html" file. Press the "go for it " button and then drag and drop to your heart’s content.

Please note: in order to provide a rich interactive experience, my interactive resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main “hess law drag & drop.html” file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work.
