This video begins by showing a demonstration of total internal reflection (TIR) through a semi-circular glass block.

It develops an understanding of TIR by showing that as the angle of incidence (θ_i) increases so too does the angle of refraction (θ_r).  Eventually, as  θ_i is...

This video shows how interference from two sound wave sources can produce both constructive (louder sound) and destructive (softer sound) interference patterns.  A demonstration using microwaves reinforces this idea. Microwaves are generated and passed through a double slit.  The resultant interference of waves is...

This booklet contains a range of suggested teaching activities and contexts for teaching about waves at A level. Curriculum links include  progressive, longitudinal, transverse, stationary, waves, intensity, electromagnetic spectrum, properties of waves, refraction, total internal reflection, superposition,...

Due to problems in the manufacture of tinplate coils, the edge of the strip can be slightly longer than the centre. This causes a 'wave' on the wall of the coil but can be rectified by differentially stretching the strip to make the edges flat. Students are required to apply Pythagoras' theorem to find the radius...

The We Are Aliens! teaching resources were produced to support the planetarium show made by NSC Creative. They have been produced by lead educators from the National Space Academy to use the context of space to teach physics, chemistry and biology in the curriculum. The resources contain practical activities,...

This Catalyst article investigates how polymer materials can be designed and printed with electrical properties that allow them to be used in wearable electronic devices. The article is from Catalyst: Secondary Science...

This Nuffield Working with Science unit was designed to help students to appreciate why the study of weather is important. The topic was planned to cover factors that influence the weather and the reasons why weather forecasters need to collect a large amount of...

This activity demonstrates how a Raspberry Pi running Python can interact with other devices in the browser. Using the web.py framework, web forms can be served to mobile phones, tablets etc, and accept input which is fed into the Python script. The project helps students to see how web servers work, and how...

In this resource students are given an image of a reciprocal curve, y=k/x. Two tangents to the curve are used, together with the coordinate axes, to form an 'arrow head' quadrilateral under the curve. The challenge is to determine the area of the quadrilateral.

The first step towards solving the problem...

In this section you will be able to explore: * The challenges and issues faced in post-16 mathematics education. *The research underpinning the approaches adopted by the Standards Unit to meet the challenges. *The experiences of the teachers and trainers in the pilot.

The Wellcome Trust Monitor is a unique survey of UK adults' and young people's views of science, biomedical research and science education.

* Wave 1 (the baseline survey) was conducted in 2009 by the National Centre for Social Research who interviewed 1,179 adults and 374 young people.
*Wave 2 was...

From the Wellcome Trust, these short animations can be downloaded and used in the classroom. The animations help students to understand a range of biological processes and diseases. These include:
* The genome, methods used in DNA sequencing and the translation and transcription of DNA into proteins
