Episode 408: Field Strength and Potential Energy

This learning episode, from the Institute of Physics, introduces field strength and potential energy for electric fields. Comparisons with gravitational fields are also made.

The activities include:
* discussion of field strength
* worked examples on field strength
* discussion about...

Episode 105: Sources of Electrical Energy

This activity from the Institute of Physics discusses energy transfer in electric circuits and links this, by analogy, to other more familiar examples.

The activities include:
• demonstrations of human and lemon-powered batteries to illustrate that that there is nothing special about the chemical...

The Big Bang Lesson

The lesson activities and resources for 'The Big Bang Lesson' are provided here for teachers and lecturers to use in their own schools and colleges.

The lesson outline includes links to many of the presentation slides used by Professor Cox in his lesson, and also to clips from Professor Cox's STAR...

Case Study: Plumbing

Produced for Future Morph, this resource contains a video in which an apprentice plumber talks about his work in a renewable energy company installing solar water panels. The theory and practicals he learns in college is applied in the workplace.

A second activity looks at a demonstration that illustrates...

Case Study: Service Engineering

Produced for Future Morph, this video sees an apprentice in service engineering talk about his work. Service engineers are mechanical engineers who work on equipment such as engines and gearboxes. The student describes how his attendance at college fits with his job in an engineering business and allows him to...

Condensation Polymerisation

Produced by Solar Spark, this activity allows students to see a condensation polymerisation reaction in action as the polyamide polymer, Nylon, is produced. This is a condensation polymer made of two parent monomers, a di-amine and a di-acid chloride.

The reaction can be used to illustrate:
*...

A Visible Activated Complex

In this classic demonstration, from the Royal Society of Chemistry, cobalt (II) chloride catalyses the reaction between hydrogen peroxide and potassium sodium tartrate. During the reaction the catalyst changes colour, showing that it is involved in the reaction.

The resource provides a list of apparatus and...

An Oscillating Reaction

In this classic demonstration, from the Royal Society of Chemistry, manganese (II) ions catalyse the reaction between bromate ions and malonic acid. The reaction oscillates between red-brown and colourless.

The resource provides a list of apparatus and chemicals needed for the experiment, together with...

The Equilibrium Between ICl and ICl3

In this classic demonstration, from the Royal Society of Chemistry, an equilibrium is set up between iodine chloride, chlorine and iodine trichloride. The amount of chlorine can be varied and the effect on equilibrium observed.

The resource provides a list of apparatus and chemicals needed for the...

Determining Relative Molecular Masses of Gases

In this classic demonstration, from the Royal Society of Chemistry, lighter gas is collected in an upturned measuring cylinder and the mass measured. Using the ideal gas equation, the relative molecular mass of the gas is determined.

The resource provides a list of apparatus and chemicals needed for the...
