Electric Sausage

In this video, produced by the National STEM Learning Centre and Network and the Institute of Physics, Michael de Podesta has a unique twist to demonstrate static electricity and charge. Small pieces of paper are attracted to a statically-charged balloon. Amazingly, so is a sausage. This short video illustrates...

Demonstrations for the Christmas Dinner Table

In this National STEM Learning Centre and Network 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...

Dry Ice Demonstration

In this National STEM Learning Centre and Network 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...

Ice Melting Blocks Demonstration

In this National STEM Learning Centre and Network 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...

Cannon Fire Demonstration

In this National STEM Learning Centre and Network 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...

Experiments in Science: Time Lapse Video

Richard Needham, from the National STEM Learning Centre and Network, 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...

Primary Science Activities for Winter

In this National STEM Learning Centre and Network video, Zoe Crompton shows two activities that primary teachers can use in the winter. Each one involves using snow or ice. The first activity is inspired by the question "Why do we put salt on the roads?" It demonstrates a fair test to compare the effectiveness of...

Electron Diffraction Tube

In this video, produced by the National STEM Learning Centre and Network and the Institute of Physics, Alom Shaha explains the elements of an electron diffraction tube and how to use one to demonstrate a diffraction pattern. The video is aimed at teachers but it could also be used with older students to...

Episode 202: Forces in Equilibrium

Produced by the Institute of Physics, this learning episode contains demonstrations and practical activities through which students learn about the conditions for static equilibrium (excluding moments of forces).

Students look at:
• forces on a horizontal washing line with a weight in the middle...

Episode 207: Projectile Motion

This learning episode, from the Institute of Physics, looks at the independence of vertical and horizontal motion. The crucial concept is that vertical acceleration does not affect horizontal velocity. This explains all projectile motion.

There are a range of activities which include:
• demonstrating...
