These downloadable videos are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to introduce ideas of the energy changes which accompany changes of state.

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop ideas relating to paper chromatography as a method for separating mixtures.

Produced by Solar Spark, this activity allows students to see a condensation polymerisation reaction in action as the polyamide polymer, Nylon, is produced. This is a condensation polymer made of two parent monomers, a di-amine and a di-acid chloride.

The reaction can be used to illustrate:
