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...

Create a den at school using this STEM challenge, which links to geography and D & T. Children learn about natural disasters and how they affect people in many ways, then are challenged to plan and construct a sturdy...

Produced by the Wellcome Trust, these animations take a detailed look at the molecular mechanisms that allow the dengue virus to subvert the cells of its mammalian host, allowing it to replicate and spread. Dengue is an example of an RNA virus.

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 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 activity supports children to work in pairs using a dental mirror and disclosing tablets to examine each other’s teeth. They then highlight the stained areas on a simple diagram and explain to their partner which areas require more thorough brushing. This activity has been provided by The Online Dentist.

The Key Stage Three National Strategy training materials produced in 2003 by the Department for Education was written to help subject leaders focus on the processes of monitoring and departmental evaluation, increase confidence in ways to prioritise developments and...

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...

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

• Describe how forces always arise in pairs

• Label force arrows to describe the action of the force

• Represent the size and direction of a force with an...
