This could be used as an AFL around the whiteboard. Open the html document by double clicking. Students drag the molecular model to the correct shape. If it’s correct it sticks. Please note: in order to provide a rich interactive experience, my drag & drop resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .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.

Drag the electronic configuration to the element, if it is correct it sticks, but not if it’s wrong. Useful as a quick AFL around the board. Helps students to quickly see patterns in the structure of the atom. Double click on the html file. No flash plugin required. I suggest you zoom out in the browser view to assist solving.

Double click the particles.html file, and the interactive drag and drop activity will open in your web browser. Drag the picture to the best description, if correct it will stick. Distinguish between pure elements, pure compound and mixtures of both. Good AFL around the board to check understanding of particles. maybe print out solution for revision.

Free radical substitution dance.

Free radical substitution dance.

Reaction mechanisms are beautiful dances, with the dancing atoms throwing out two (heterolytic ) or one (homolytic) arms out to their partner. Thus, I added a little beat to this reaction mechanism.
