As it says on the tin. AQA GCSE science.

A simple simulation of the experiment. Unzip the file. Open the folder. Double click on ‘spring stretch version 4.html’ and it opens in your browser. Add the masses by clicking the buttons, and watch the spring stretch. Use a ruler to measure the extension. (The anomaly on the graph at 3N is probably due to a draught of warm air expanding the spring as a door was opened). Enjoy! A preview is availableon my web site. 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. ©D&D production

A simple worksheet.

As the title. Based on AQA GCSE specification.

for my amusement

summer science mega wordsearch no 2

I made a worksheet for this common experiment. It might be of use to someone.

A very simple worksheet. ( I have now removed the duplicated lamp symbol).

a simple summary

I made a simple worksheet about density. 5 pages. Two of info, one table of values, a page of questions and my answers. I have now added a keynote and powerpoint version.

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.

I made a very simple wordsearch. Update: I know have added a labelling exercise to compliment this

A simple summary sheet.

Could be useful at the end of term. Students could then research some scientists of whom they hadn’t heard.

I have made a simple information sheet for this important, but much neglected, topic.

I made a tiny, simple little interactive animation thingy to illustrate particles in a clunky kind of way. Just the three states of matter. 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 in your web browser… If, however , you move or delete any of the files from this hierarchy, the resource will not work. stdobbs.com ©D&D production

I made a simple display of the atomic structure of various isotopes, with the emphasis on simplicity and clarity. Just because I wanted to. I also included it as keynote and powerpoint presentations.

I made a wacky presentation showing some constellations, and a tiny bit of information on the solar system. I also made a movie of the presentation set to music. Just for fun really.

A simple information sheet, with the emphasis on clarity. It may be useful to someone, somewhere.

A simple worksheet about the evolutionary cycle for stars. Part of my “label it” series.
