Hydrocarbons drag & drop

Drag the structure to the name and drop… If it is correct it sticks. Useful around the whiteboard for AFL. Simply open the html file. 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.

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.

Burning ethane. If I burn 10g of ethane, how much carbon dioxide will I get? A simple powerpoint show. Two slightly different approaches are illustrated, , you could use either or both ( I have now corrected the error in the equation.)

This is a very simple worksheet. Link the name of the polymer to its monomer. Then draw the repeating unit. A drag and drop version may follow. Watch this space.

An explanation of paper chromatography in a movie, with voiceover. In this animation, the dyes don’t smear, so students can see what is meant to happen, rather than what really does.

An introductory sheet of answers, followed by cut and stick exercise for this challenging mechanism. Cut and stick promotes familiarity with the mechanism, promotes discussion when done in groups, and is enjoyed immensely by sixth formers.

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.

Sixth formers love cut & stick exercises. They are valuable because they familiarise the student with the mechanism, they promote discussion when done in groups, and are different to taking notes and practical work.
