Homeostatic imbalances, which occur when feedback loops are broken or altered, can have very serious, or even fatal, consequences. This video covers diabetes, hyperthyroidism and hypothyroidism, explaining in detail how they result from malfunctions of homeostatic processes and discussing the impact they have on people suffering from these conditions. An informative, curriculum-relevant video for senior secondary Biology students and above. Show Less

Body systems, particularly the nervous and endocrine systems, play an important role in maintaining homeostasis and they are highly developed in mammals. This video investigates the role of body systems in maintaining a steady state, detailing how different systems work together in the homeostatic mechanisms of thermoregulation and osmoregulation. An informative, curriculum-relevant video for senior secondary Biology students and above. Show Less

Homeostasis is required for healthy functioning and is achieved when the conditions within the body are in a steady state. This video looks at homeostasis and dynamic equilibrium in the human body, explaining step-by-step how homeostatic processes ensure that blood glucose and carbon dioxide levels are maintained at normal levels. An informative, curriculum-relevant video for senior secondary Biology students and above. Show Less

Homeostasis maintains internal conditions so that cells can function normally, fundamentally contributing to survival and good health. This video looks at homeostatic processes in single-celled and multicellular organisms, explaining the critical role that homeostasis plays in the functioning of cells, organs and body systems by regulating temperature, nutrients, electrolytes and oxygen. An informative, curriculum-relevant video for senior secondary Biology students and above. Show Less

Homeostatic processes occur in a range of organisms, enabling them to withstand a wide range of changes in the external environment. This video covers the basic facts about homeostasis with a focus on thermoregulation in the human body, explaining key terms such as steady state, negative feedback loop and set point. An informative, curriculum-relevant video for senior secondary Biology students and above. Show Less

In this episode, we look at how electrical equipment is designed to use the right amount of current for the voltage supply that it's designed for. After a brief recap on electric current, we look at what voltage is and how it is measured. we then look at the concept of resistance. At a simple level, some materials are conductors and some materials are insulators, but not all conductors conduct equally well. The amount of current that flows in a household appliance depends on the appliance's resistance Show Less

In the sea life is everywhere, but five habitats are like underwater cities. They are coral reefs, mangroves, salt marshes, sea grass beds and kelp forests. They provide safety, food, and a nursery for the young of many species. Yet they are in critical danger because we humans are rapidly destroying them. This programme seeks to explain why these five habitats are very important to life in the sea and to point to the fact that they are all in decline. They are being damaged by human activity... some are being cleared away for ports or housing, some are damaged by trawling nets or dredge silt, as well as pollution, overfishing, or the slow but undeniable outcomes of global warming... to name only a few of the reasons. We need to try and stop this worrying trend. Show Less

For many new agricultural technologies, feasibility issues need to be considered before they can be adopted by farmers and businesses.

In the second episode, we examine how lights, switches, and other electrical devices are all connected either in "series" or in "parallel" with each other. How do they wire up the lights in your house so that in some rooms the light switch turns on only one light but in other rooms the light switch switches on two (or more) lights? And how is everything wired up so as to allow us to turn the lights on and off in different rooms independently of one another. Well, don't wait at the terminal, jump on board. Show Less

In episode three, we take a look at what electric current is (it's basically the flow of electrons through a wire) and at how electric current is measured. We then examine the different ways that electric current flows in series and parallel circuits. Show Less

This programme is about seawater. It is the most important liquid on Earth, not only from its sheer volume, but also because it has remarkable qualities. A few of them, like buoyancy, are common to all liquids - but seawater is also the cradle of life. Three key factors of water underpin life in the sea: water’s dissolving power, its tendency to keep a stable temperature, and its transparency to light. This programme explains the mechanisms and the outcomes of these key facts—and other things—that make seawater both weird and wonderful. Show Less
