Iron filings in 3D

Seeing old things n a new way is often what sparks off the imagination and the want and desire to find out new things in science. Using this 3D view of iron filings does just this. Leave it out in the lab for the students to find.

Organic Synthesis

 Starting the organic synthesis pathway diagram I was taught this by my Chemistry teacher some 40 years ago and it is still as relevant today.

Optics

 I find it a shame that some things creep out of syllabi. Less and less is done on optics and the students have little idea of the nature of lenses and images. In the Edexcel syllabus we spend time understanding why the candle was upside down on the screen.

Like and unlike charges

 Like charges repel and unlike charges attract

Looking at the converging lens

 These flat lenses work well with the @pasco light with its 5 ray beams. Working in a Light box the students can work in bright daylight and get excellent results.

Carbon Nanotubes

 This is not a model in the molymod range, but one  I made to shown how graphene can be rolled up into a carbon nanotube. It gave the students much to discuss about new materials and composite materials. Making bullet resistant material was a fun topic to look at these materials.

Pasco Spectrometer

There are many favourite practicals, but seeing the spectrum of light from different glowing chemicals is certainly one of them. The @pasco.scientific spectrometer gives an insight into an unseen world around us.
