For GCSE chemistry enjoyment

I made a clunky little video about this.

I made this set of exam questions around glycerol. It has six questions over two sides.

Part of my series of A level style questions. Two pages with six questions.

Part of a bundled series.

I made a crazy video about Ohm’s law. Resistance is futile.

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. Molnupiravir has recently been approved as an anti COVID drug, so is of topical interest. Comprises 7 questions over 2 sides.

I made a little video of polymerising ethene. It probably will be of no use at all.

I made a clunky cartoon about cracking alkanes with a cheery soundtrack. The idea is for students to write and record the narration… something different to just ‘writing up’ the experiment.

This is quite a challenging wordsearch, although it appears simple. ( I have now included a pdf of 30 atomic structure bingo cards)

I have made a little interactive cartoon thingy to reinforce or introduce the two types of bond fission, heterolysis and homolysis. Just click on the bond fission html file and it opens in your browser. You can make it huge using the browser zoom controls. 19.9.19- apologies the file previously uploaded was done in error. It should now work 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
