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

For many new agricultural technologies, feasibility issues need to be considered before they can be adopted by farmers and businesses. This video explains why scientific verification and practical adoption of technology are both important and discusses the long-term aims of new technologies, with insight from scientists at agricultural research institutes. A highly relevant resource for senior secondary and tertiary students studying design technology, earth and environmental sciences or agriculture. Show Less

New technologies in the agricultural industry can have environmental, social and economic impacts.

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

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. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less

The skeleton plays a crucial role in all vertebrates, including humans. This video introduces viewers to the role of the human skeleton, covering the key functions of shape, movement, protection, blood cell production and mineral storage. Detailed animated graphics paired with clear definitions and examples makes this essential viewing for secondary students studying the human body. Show Less

There are many diseases, both historical and still widespread today, that are related to the health of our bones. This video discusses rickets, spina bifida, scoliosis, osteoporosis and arthritis, explaining their causes and methods of treatment or prevention. Detailed animated graphics paired with clear definitions and examples makes this essential viewing for secondary students studying the human body. Show Less

Knowing what bones are made from is essential for understanding what happens when they break and mend. This video guides viewers through the minerals and proteins in bones and the two types of bone tissue, then explains the various classifications of bone fractures, including the healing process. Detailed animated graphics paired with clear definitions and examples makes this essential viewing for secondary students studying the human body. Show Less

The points at which bones connect with each other, or the joints, are critical for the body’s range of movement. This video explains the structural and functional classifications of joints, providing detailed descriptions and examples of fibrous joints, cartilaginous joints and the six types of synovial joints. Detailed animated graphics paired with clear definitions and examples makes this essential viewing for secondary students studying the human body. Show Less

The human skeleton contains up to 206 bones, arranged in a particular structure to fulfil their unique functions. This video comprehensively covers different types of bones and their function, the axial and appendicular skeletons and includes a focus on the vertebrae and the skull. Detailed animated graphics paired with clear definitions and examples makes this essential viewing for secondary students studying the human body. Show Less

"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

"Following the Sun" looks at how the sun's movement across the sky every day changes. In summer, the sun reaches a much higher angle in the sky than it does in winter. This affects the design of energy-efficient homes and the placement of solar panels. Show Less

How is chemical equilibrium important for making ammonia?
