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=...
