Climate Change's Deadly Trio

Climate Change's Deadly Trio

Life in the Sea

The deadly trio of climate change in the sea is warming water, oxygen depletion and ocean acidification. This programme looks at how these are affecting the underwater world. Creatures are reacting in different ways, from migrating to cooler...Show More
Colours, Waves and Particles

Colours, Waves and Particles

Light Fantastic

Every time you’re seeing an object, it’s all thanks to light. This video explains electromagnetic radiation, the visible light spectrum and how light travels as waves but behaves as particles, through engaging visuals and informative diagrams.
Refraction, Lenses and Polarisation

Refraction, Lenses and Polarisation

Light Fantastic

When light travels from one medium into another, its speed changes – that’s refraction! This video demonstrates refractions and explains how lenses work and how polarisation filters light, through engaging visuals and informative diagrams.
Reflection and Mirrors

Reflection and Mirrors

Light Fantastic

Objects can only be seen because they reflect light. This video explains how objects absorb and reflect different wavelengths, how mirrors work, and why the shape of a surface impacts reflection, through engaging visuals and informative diagrams.
Beta-Minus and Gamma Radiation

Beta-Minus and Gamma Radiation

Shedding Light on Nuclear Radiation

This video looks at what beta-minus and gamma radiation are, and how thye are put to good use in medicine and in industry.
Alpha Radiation

Alpha Radiation

Shedding Light on Nuclear Radiation

In this episode, we look at what alpha particles are, introduce students to nuclear equations, and show how alpha-emitting substances are used to power space probes and to treat certain types of cancer.
Atomic Structure

Atomic Structure

Shedding Light on Nuclear Radiation

In the first episode of this series, we lay down the foundation on which the series is built: what atoms are made of and how atoms differ. We look at protons, neutrons, electrons and learn about isotopes and nuclides.
Half-Life and Activity

Half-Life and Activity

Shedding Light on Nuclear Radiation

In this video, we examine how quickly radiation is given of by radation-emitting substances. Some radioactive substances emit lots of radiation in a short amount f time while other emit radiation very slowly. These different rates of emission can...Show More
