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.

Complemented by clear, illustrative diagrams, this is a valuable resource for secondary students of science. Show Less

The kidneys play a vital role in the body by filtering blood, removing wastes and producing urine. This dissection of a pig’s kidney shows the structure of the kidney, including the renal artery and vein, the renal pelvis, cortex and medulla, nephrons and renal pyramids, and explains its function as part of the urinary system. Complemented by clear, illustrative diagrams, this is a valuable resource for secondary students of science. 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.

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

The terrestrial zone is the area of land around the pond that is not regularly inundated with water. This video looks at biotic and abiotic factors in the terrestrial zone, discussing the flora and fauna found in this zone and the potential impact human activity can have on the whole pond. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less

The organisms found in the littoral zone are critical for the biological cycling of abiotic factors. This video explores the complex relationships between primary producers, lower level consumers and higher order consumers and how they can be modelled using food chains and food webs. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less

The euphotic and profundal zones, which together comprise the limnetic zone, are home to a variety of organisms. This video looks at the characteristics of primary producers and consumers and how energy is transferred and lost through the different levels in a food chain. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less

The benthic zone teems with life and biodiversity and acts like the digestive system of the pond. This video explains how organisms here have adapted to living in conditions of low light and low oxygen and why they are crucial for processes of nutrient cycling and maintaining water quality. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less

The plants found in the littoral zone play an important role in maintaining and supporting the biotic and abiotic conditions of a healthy pond. This video explains how these plants photosynthesise, looking at the role reeds and rushes play in transforming sunlight into energy that flows through the ecosystem. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less

A pond is an ideal place to see how living and non-living things interact with each other and their environment. This video introduces key aspects of pond ecosystems, explaining how abiotic factors define the four pond zones and how relationships between organisms can be modelled with food chains and food webs.

"Land and Ocean" examines who the world's land masses and oceans affect global climate patterns. We look at why the air gets colder and colder the higher you go, why coastal regions don't heat up or cool down as much as inland regions, why winters are colder in the northern hemisphere, and a whole lot more Show Less

In this episode, we describe how tropical cyclones form and examine their huge power. We explain what the Coriolis effect is and how it make tropical cyclones rotate the way that they do. We also travel to three continents to demonstrate how Coriolis effect affects water draining from a small container. Does water really swirl in a different direction depending on which hemisphere it is in? Show Less
