In this video, produced by Teachers TV, Dr Shini Somarathne presents a run-down of the top ten experiments that go wrong for teachers, compiled by school science support service CLEAPSS. Expert chemists Dr Colin Osborne from the Royal Society of Chemistry, and Dr Kay Stephenson and Bob Worley from CLEAPSS...

In this programme, from Teachers TV, David Richardson from the Institute of Physics demonstrate his physics experiments on...

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 diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Describe characteristics of objects or substances with high (or low) densities.
• Compare the density of objects that differ in both mass and volume.
• Explain the equation ρ=...

Produced by The Centre for Industry Education Collaboration (CIEC), this resource looks at the testing of materials in the context of dentistry. Students first look at the properties of teeth and the nature of toothache before going on to test materials for a range of properties.

Experimental methods...

This video for a-level and GCSE high ability students looks at how we derive units.  It looks at why speed can be measured in m/s and then goes onto to look at the units for force using F=ma and also why we use Joules for energy.  It also discusses the seven main base units and how all units are derived from these...
