There is a beautiful graphic depicting this on the internet. However, it is a bitmapped graphic . I have adapted it as a a scalar graphic, with improvements. Please get in touch if you want an editable version.

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.
Classification hierarchy drag&drop

Classification hierarchy drag&drop

A wacky classification interactive activity that might amuse some students. Double click on the .html file and it will open in your browser. Drag the components into the correct order. You could make it huge using browser zoom controls. I have added a funky soundtrack to spice it up a bit. 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.

simple quick video, three chromosomes, maybe students can shout out the stages. (hope it’s accurate enough, if not students can point out the errors!)

Exam boards often take unknown substances and ask students to apply their understanding of chemistry to them. To provide practice answering this type of question, I am developing a series of worksheets with this type of question. The series is called “Practicexamquest.”
Nucleophilic substitution Sn2 versus Sn1

Nucleophilic substitution Sn2 versus Sn1

I have made a little movie to simply distinguish between SN1 and SN2. It is similar my youtube video shown ( no music though- if you want that, just use the youtube!) I have not added commentary, leaving that to the teacher. If required, I could add it. Update: now sn1 improved so it is more simultaneous. 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 .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.

I have tried to illustrate the concept of separation of water molecules rather than breaking covalent bonds when water is heated with a quick and dirty animation. Click on the water boiling.html file and it will run in your browser.
