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,...

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 video features interviews with three space scientists: Becca Wilson – a planetary scientist at the University of Leicester; Euan Monaghan – a PhD student in planetary science and astrobiology at the Open University; and Louisa Preston – a post doctoral research fellow in planetary geology and astrobiology at...

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...

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
*...

Produced by the Wellcome Trust, these resources include an interactive evolutionary tree and a video of the Tree of Life. These materials will help students to find out more about the work of Charles Darwin and evolution. The resources contain:

Tree of life video: The video is a short...

This Catalyst article looks at sperm whales and their ways of communications. Sperm whales can dive deep into the ocean. They use sound waves to communicate in the dark and to detect their prey.

This article is from Catalyst: Secondary Science Review 2016, Volume...

A Catalyst article about whaling. During the last century whales were hunted and killed by many nations for the valuable materials they provided. Whale populations collapsed as a result. The article looks in detail at this example of human impact on the environment and details whale populations throughout the world...

This Catalyst article explains the use of stem cells to treat medical problems, and outlines new possibilities for the use of adult stem cells in treatment.

Currently, stem cells used for treatment are embryonic stem cells, since they have the ability to form any cell type in the body. The example of the use...
