From water to table salt, we safely come into contact with countless chemical compounds every day. But compounds can also be deadly. Using Turkish President Turgut Özal’s death and eventual autopsy as real-life context, this video examines the chemical and structural qualities of compounds—in particular, the toxic pesticide known as DDT. Complemented by clear graphics, it is essential viewing for students of chemistry. Show Less

The products of mining—metals, minerals and fuels—are essential to our everyday lives. But the waste by-products from mining processes, called tailings, can be highly toxic. Using the 2014 Mount Polley Mine tailings dam and its catastrophic release of toxic chemical mixtures into the environment as an example, this video explores the make-up of mixtures, identifying the differences between solutions, colloids and suspensions. Complemented by clear graphics, it is essential viewing for students of chemistry. Show Less

Explore the physical and human cause of the Somerset floods with this engaging resource. Then consider their impact on people's lives, the environment and property, before assessing how both hard and soft engineering options are being used to improve resilience to future flood events. Show Less

Yahya's family has been forced off their land on the fringes of the Sahara, because of desertification. Through his story, this title considers the impacts of desertification and its causes, including: climate change, population pressure, over abstraction of water, overgrazing and salinisation. It then considers a range of responses including tree planting, the use of appropriate technology and the introduction of sustainable water and soil management strategies. Show Less

Using Morocco's Sahara Desert as a case study, this title considers the challenges of hot desert environments, including extreme temperatures, lack kof water and inaccessibility. It then looks at the opportunities deserts can offer if these challenges can be overcome. Show Less

Use this programme to explore what makes landscapes distinctive in the UK. It provides an overview of the characteristics and uses of the UK's areas of upland and lowland landscapes. Through the use of case tudies, this video contextualises how climate, geology and human activity have worked together in combination with geomorpic processes over millions of years, to create the UK's diverse and distinct landscapes.

According to the UN 1.5 billion people are affected by desertification. This film follows the fortune of one family forced off their land on the fringes of the Sahara. Through their story this title considers the impacts and causes of desertification. It then looks at a range of responses including tree planting, use of appropriate technology and the introductino f sustainable water and soil management strategies. Show Less

This programme looks at the different ways people living on the world’s desert margins are rising to the challenge of desertification and making the most of the opportunities deserts can offer. Along the way viewers find out about the world’s largest solar plant, the “Hollywood of the desert” film studios where Game of Thrones is filmed, large scale irrigation schemes used for citrus cultivation, mineral extraction and luxury desert tourism.

This clip explores the hazards associated with earthquakes and volcanic eruptions, including ash pollution and the destruction caused by explosions, lahars, pyroclastic flows and tephra in volcanic areas; and tsunamis, disruption of services, destruction of property and infrastructure and loss of lives in earthquake zones. Show Less

Using the emergency response to the Haiti earthquake as an example, this clip considers the effectiveness of a variety of disaster management strategies. Examples include short-term responses like evacuation, search and rescue and the delivery of emergency food, water and medical supplies. The long-term responses are also considered and include the rebuilding of infrastructure and provision of health care. Show Less

This clip compares how tropical rainforests and mangroves have adapted to their environments. We explore how despite sharing the same climatic conditions, mangroves face an additional challenges because of their coastal location. We see examples of how rainforests have adapted to their warm, damp environment including: the forest structure, drip tip leaves, lianas, buttress roots, epiphytes. This is then compared with how mangroves have adapted to survive in brackish water and waterlogged soil, i.e. through root adaptations. Filmed in a variety of rainforest and mangrove locations around the world. Show Less

A poisoned umbrella and a forensic investigation…using an unusual and as-yet-unsolved true crime as a launching place, this video shows that the chemistry of matter matters. Elements, as represented on the periodic table, are made up of only one type of atom. Using mercury—and mercury poisoning—as an example, this video examines the chemical and structural qualities of elements and the anomalies that make mercury unusual. Complemented by clear graphics, it is essential viewing for students of chemistry. Show Less

Matter exists as elements, compounds and mixtures. But what are the differences between these three forms? Using straightforward images and diagrams and commonplace examples, this video introduces students to how elements, compounds and mixtures are formed, how they bond and combine, and if and how they separate. Succinct and clear, this is essential viewing for students of chemistry. Show Less

This dissection of a bovine male reproductive tract explores the physical structure of the penis, scrotum and testes, and the various muscles and tissues that allow the organs to move, extend and retract during mating. The video describes the process of sperm production and the path it travels to eventual ejaculation. Complemented by clear, illustrative diagrams, this is a valuable resource for secondary students of science. Show Less

This dissection of a bovine female reproductive tract explores the physical structure of the vulva, vagina, cervix, uterus and ovaries, describing the process of reproduction from hormonal triggers, to ovulation, to the path of sperm as fertilisation occurs. Complemented by clear, illustrative diagrams, this is a valuable resource for secondary students of science. Show Less

Pluck refers to the internal organs of an animal, including the tongue, larynx, oesophagus, heart, lungs and diaphragm. In this dissection, these organs are studied in detail to show their roles in supporting the body’s many systems including the transportation of air, blood and food through the body. Complemented by clear, illustrative diagrams, this is a valuable resource for secondary students of science. Show Less

This dissection looks at the external and internal features of the testis of a male pig, describing how the testis and its two main types of cells – germ cells and Leydig cells – function in sperm and hormone production. Complemented by clear, illustrative diagrams, this is a valuable resource for secondary students of science. Show Less

A comprehensive exploration of the internal organs, this dissection of a piglet that did not survive the birthing process studies the full animal from top to tail. Describing the physical mechanics of dissecting a whole animal as well as the notable features of each organ, the video is a comprehensive and practical guide. Complemented by clear, illustrative diagrams, this is a valuable resource for secondary students of science. Show Less
