Astronomy and Cosmology

Exploring Space

Over thousands of years, humans have developed our understanding of the stars and planets through the twin sciences of astronomy and cosmology. This video takes viewers through the history of humans studying the skies, exploring the links between...Show More

Bovine Eye

Dissections for the Science Classroom

Forming part of the nervous system, the eyes are complex organs responsible for receiving light from the environment and conveying this information through nerve signals to the brain. This dissection of a cow’s eye shows the optic nerve,...Show More

Ovine Brain

Dissections for the Science Classroom

Acting as the body’s control centre, the brain is responsible for all the essential functions of the body. This dissection of a sheep’s brain, complemented by clear, illustrative diagrams, looks at the brain’s two hemispheres and their four...Show More

Porcine Kidney

Dissections for the Science Classroom

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,...Show More

Ovine Heart

Dissections for the Science Classroom

The central component of the circulatory system, the heart plays a vital role in moving nutrients and waste around the body. This dissection of a sheep’s heart shows the structure of the organ, including its chambers, veins, arteries and...Show More
Homeostasis and Disease

Homeostasis and Disease

Homeostasis

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...Show More
Body Systems and Homeostasis

Body Systems and Homeostasis

Homeostasis

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...Show More
Maintaining Homeostasis

Maintaining Homeostasis

Homeostasis

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...Show More
The Impact on Body Functions

The Impact on Body Functions

Homeostasis

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...Show More
What Is Homeostasis?

What Is Homeostasis?

Homeostasis

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,...Show More

Electrical Safety

Shedding Light on Electricity

In "Electrical Safety", we first look at the dangers of electric shocks by actually demonstrating an electric shock. We then look at the safety features built into our homes and electrical devices that keep us safe from electric shocks.

Voltage, Current, and Resistance

Shedding Light on Electricity

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...Show More
5 Critical Habitats

5 Critical Habitats

Life in the Sea

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...Show More

Defining the Problem

Agriculture and Technology

Agricultural processes have a large-scale impact on natural resources and ecosystems and many businesses are turning to technology to help. This video introduces some issues that agricultural technologies aim to address, including water scarcity,...Show More
Developing Technological Solutions

Developing Technological Solutions

Agriculture and Technology

Before agricultural technologies can be adopted by businesses, they need to be thoroughly tested and evaluated. This video looks at the techniques and systems researchers use to collect and evaluate data, such as internet-connected sensors and...Show More
Sources of Electricity

Sources of Electricity

Shedding Light on Electricity

In 'Sources of Electricity', we take a detailed look at where our electricity comes from: thermal and hydroelectric power stations, wind farms, and solar farms. We alo examine the advantages and disadvantages of these sources of electricity.
Electric Circuits

Electric Circuits

Shedding Light on Electricity

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...Show More
Electric Currents

Electric Currents

Shedding Light on Electricity

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...Show More
