The development of atomic models over time.

I made this diagram of the iconic gas diffusion rate demonstration. Hope it is useful to someone, somewhere.

The traditional textbook graph of this data is very confused. I feel that my presentation of the data emphasizes the role played by hydrogen bonding more clearly. The influence of atomic size on boiling point is also clearly shown by the bp of the noble gases.

summer science mega wordsearch no 2

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

I made a very short, simple presentation . Powerpoint & keynote versions.

I made a simple presentation. Powerpoint and Keynote versions

for my amusement

I made a whacky revision cartoon thingy about the motor effect and fleming’s left hand rule. Just for fun really. (the youtube version has narrative)

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.

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

Bah Humbug. For your students’ (mild) entertainment around christmas. With a tiny bit of science in it. And some Latin.

I have added the new definitions to the SI wheel of units. Possibly for display in your lab.

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

A simple wordsearch on energy & electricity. Word searches help concentrate on scientific literacy and aid concentration. they are good summary activities and for revision. I have tried to make this attractive and efficacious in that it uses only one side of A4.

a simple summary

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

The clunkiest video ever produced…

I made a simple Venn diagram to put these into context. Students find this area difficult.

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.
