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 downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop ideas relating to the intrinsic motion of particles and diffusion phenomena...

This short film clip follows primary school teacher, Danny, as he demonstrates a practical experiment which recreates the digestion process in the classroom. Using household items such as paper cups, orange juice and a pair of tights, this demonstration enables children to visualise the process of digestion in an...

This A-level tutorial video follows on from the the distance, speed and time video.  It looks at the terms displacement and velocity and how they differ from speed and time.  An example of a displacement / time and velocity / time graph is given and discussed.  A...

With this a-level video tutorial, the presenter talks about how we get the equation speed = distance / time and then looks at the differences between a distance / time and a speed / time graph.  It also demonstrates what the area under the graph represents as well as the gradient.  This can be followed by the...

This video asks people if they believe cell phones can cause cancer.  It then considers the available evidence logically, that is types of radiation emitted by a cell phone (non-ionising) and the power rating to conclude that the radiation should not be harmful. However, recent evidence suggests that heat-shock...

This resource provides a set of videos and a practical investigation aimed at supporting working scientifically in the classroom and relating science to real world experiences. In the first video Professor Brian Cox joins a teacher to find out how to set up and run an investigation to find out if plants need soil...

Video from the Big Picture issue on Fat, showing an experiment to discover if we favour fatty foods.

This video demonstrates how applying pressure to ice melts it, yet on removal of the pressure the ice re-freezes.  This is called regelation.
