Experiments in Science: Time Lapse Video
Richard Needham, from the National Science Learning Centre, demonstrates how to use time lapse video to speed up action that would otherwise be either too slow to notice within a normal school science lesson, or to provide opportunities to explore gradual changes outside a classroom. Examples of biology experiments which could…

Ice Melting Blocks Demonstration
In this National Science Learning Centre video, Simon Quinnell investigates the way different materials conduct heat using conductivity blocks and ice cubes. The video shows how the ice cubes melt at different rates depending on the thermal conductivity of the materials they are sitting on. Simon explains how this experiment can…
Demonstrations for the Christmas Dinner Table
In this Science Learning Centre video, Simon Quinnell demonstrates four experiments, with the theme of Christmas, that teachers can do in the school laboratory. These are: • Tea bag convection - see how a burning teabag mysteriously rises on convection currents in the air around it. • The candle demonstration - generate…
Cannon Fire Demonstration
In this Science Learning Centre video, Simon Quinnell demonstrates a spectacular and noisy experiment showing the oxidisation of hydrogen peroxide using ethanol and potassium permanganate. An exciting illustration of energy changes, the sound of these substances reacting with each other sounds like cannon fire.
Dry Ice Demonstration
In this National Science Learning Centre video, Simon Quinnell demonstrates an experiment using solid carbon dioxide (dry ice) and sodium hydroxide which is likely to impress students. The experiment can be used to talk about the properties of solids, liquids and gases, acids and alkalis or used as an open evening demonstration.…
