Episode 315: The Inverse Square Law

In this learning episode, produced by the Institute of Physics, students investigate how the intensity of radiation decreases with distance from the source.

The activities include:
* demonstration and discussion on how radiation spreads
* worked example to illustrate thinking in proportions...

Episode 317: Reflection and Refraction of Waves

This learning episode, from the Institute of Physics, contains activities in which students look at reflection, refraction and Snell's law.

Through discussion, demonstration and practical experiments, students look at:
* reflection and refraction with a ripple tank
* the 'marching soldiers'...

Episode 318: Total Internal Reflection

Produced by the Institute of Physics, this learning episode helps students to observe total internal reflection (TIR) as a consequence of refraction. Students use a semi-circular block to observe TIR and see how a fibre optic can be used to transmit information.

The activities include:
* ray tracing...

Episode 322: Diffraction Gratings

In this learning episode, from the Institute of Physics, students look at different light sources through diffraction gratings. Using this system, students measure the wavelength of a laser and derive the grating formula.

The activities include:
* looking through gratings
* deriving the grating...

Episode 324: Stationary or Standing Waves

In this learning episode, from the Institute of Physics, students look at standing waves in musical instruments and measure their wavelength. Microwaves are used to estimate the speed of light.

The activities include:
* demonstrating waves in a rope
* how superposition results in standing waves...

Episode 406: Fields, Field Lines and Equipotentials

Produced by the Institute of Physics, this learning episode introduce students to electric fields, field lines and equipotentials. Similarities with gravitational fields are highlighted, but with the need to take account of the of charge.

The activities include:
• discussion and demonstration of field...

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...

ICT in Practical Science: New Approaches to Data Collection and Analysis

These resources were developed by the Gatsby Science Enhancement Programme and the Centre for Science Education at Sheffield Hallam University in order to demonstrate new ways that ICT can be used to enhance practical work in science. Research scientists use computer technology in both the collection and the...
