I have made a wacky simulation of the extending spring experiment. Opens in your browser. Press the buttons to add the masses. Measure the spring. 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. stdobbs.com ©D&D production

Whacky narrated video showing how to answer the ‘draw a ray diagram to show the formation of an image by a plane mirror’ type question.

I made a tiny, simple little interactive animation thingy to illustrate particles in a clunky kind of way. Just the three states of matter.

I set this to a funky beat, in an attempt to aid memory. Play it over and over again. If it’s too large to download, you could play it directly from this page, pressing the fill screen button. Why not play it at the end of many lessons, getting students to chant the names of the functional groups as they appear? A real process of learning.
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.

Match the definition to the word. Words taken for AQA GCSE science ‘how science works’ Please note: this can be printed on two sides of the same sheet, because the definitions are on the same side- no need to keep turning over. Update: I have now included a simple presentation with the definitions.
