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 distinct lobes, explaining the unique features and functions of each. This video is informative viewing alongside or in place of a hands-on dissection. Show Less

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

The word pandemic comes from Greek and means “pertaining to all people”. At the end of 2019, the infectious disease covid-19 was discovered. It then spread all over the world, which had enormous consequences for millions of people. In this educational clip, we go through what characterizes a pandemic. You will learn about known pandemics such as the Great Death, the Spanish flu, the Asian, the Hong Kong flu and the swine flu. You will also learn concepts such as infodemias, as well as the importance of credible sources in times when false rumors spread quickly. Show Less

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, cornea, pupil, iris and retina, and explains the process of how the eye communicates with the brain to achieve sight. Complemented by clear, illustrative diagrams, this is a valuable resource for secondary students of science. 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

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 passages, and explains the role it has in ensuring blood flow around the body. 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.

It's time to start going through a variety of common viruses, so let's start with the most common one of them all, the one that most often causes the common cold. It's called Rhinovirus, and it is a member of the picornavirus family. What does that mean? What are these like? How do they operate? Let's learn all about rhinoviruses! Show Less

In this video, we learn about forests, one of the world’s biggest biomes. We’ll start by discussing what a forest really is - because it’s a lot more than just trees! The forest is in many ways a key resource, above all for the climate, but also for the economy. The forest absorbs part of the carbon dioxide we release when we burn fossil fuels. We learn about the layers that make up a forest. We also take a closer look at the types of forest that exist and what plants and animals we find there. Why do leaves change color in the fall? We’ll learn that too. 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
