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:
*...

This downloadable video is part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). It can be used to show water condensing out of the air. A pure sample of water is normally in the liquid state at room temperature, but water particles can remain separated...

This video is the full experiment in real time to investigate the rate of conduction in various metals.

This video demonstrates a convection experiment for GCSE Physics using potassium permanganate in water with a Bunsen burner.

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 the idea that substances in the solid state usually consist of crystals, even though...

In this activity developed by the Institute of Physics, students model the motion of a planet around a star and investigate how day and night and seasons may be different on other planets. Working in pairs or small groups, students demonstrate night and day and seasons to each other. They can then go on to model...

A pair of videos that investigates the density of different materials.  The first allows students to see an experiment on the density of regular and irregular objects from home. The second part outlines the calculations used to work out the densities of cylinders of different materials. This is a required practical...

These downloadable animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to introduce density as a property to identify substances.

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 the intrinsic motion of particles and diffusion phenomena...

This video demonstrates an experiment to investigate how current affects the strength of a magnetic field. The Phyphox app on a mobile phone is used to measure the magnetic field strength. The second part explains how to plot a graph to evaluate the relationship between current and magnetic field strength.
