I post things that are finished and that work. I make resources when I can't find anything that works in the way which I want it to. If they don't work for you then let me know through the comments section and I'll try to put them right. If they do work and you like them then please comment too. Some things take a long time to make and to get right... so I charge a little for those.

Four clear powerpoint slides that show crystallinity in HDPE, random chains in LDPE, thermosetting polymers and thermosoftening polymers.\nI go through it using the IWB but print out the slides, two on a paged,backed, without the diagrams, to give pupils the opportunity to draw out the different structures.

I don't know what prompted it but a student asked me, 'How many atoms are there in me?' After a quick calculation based on her mass and the atoms all being carbon, the number was too big to visualise. Hence the subsequent question from the same student, 'So how big would that be if every atom was a one pence piece?'\n\nThis is the result. Thanks Niamh, for the original question

This can be used as an introduction to ethene. It is designed to help students link the displayed formula, that is common in texts, to the idea of a covalent bond being a shared pair of electrons.\n\nComments and feedback are welcome

This powerpoint is meant to be used in conjunction with a molecular modelling kit. Students work in groups to build what they think are the isomers called for. They can then rotate the chains to find out which ones are the same.\n\nNamenclature can also be tested\n\nComments welcome.
