Extreme Weather

Miniclips: Earth's Changing Surface

Heat waves, tropical cyclones, droughts, tornadoes, hailstorms, floods, and severe thunderstorms. These are all examples of extreme weather that shape our landscape. But what exactly are they and how do they happen? This Miniclip explores each of...Show More

Erosion

Miniclips: Earth's Changing Surface

Some of Earth’s magnificent landforms are caused by erosion and weathering. But what is erosion and how does it change the Earth’s surface so drastically? This Miniclip explains the process of erosion including the various mechanisms such as...Show More

Weathering

Miniclips: Earth's Changing Surface

Some of Earth’s magnificent landforms are caused by weathering and erosion. But what is weathering and how does it create magnificent structures on our planet? This Miniclip explains the process of weathering including the two main types:...Show More

The Challenges of New Technologies

Agriculture and Technology

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...Show More

Impact of New Technologies

Agriculture and Technology

New technologies in the agricultural industry can have environmental, social and economic impacts. This video explores the technology that targets methane emissions, how fruit yield and quality can lead to greater profitability and how commercial...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

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
Weird Wonderful Water

Weird Wonderful Water

Life in the Sea

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...Show More
Land and Ocean

Land and Ocean

Shedding Light on the Sun and Earth

"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...Show More
The Coriolis Effect

The Coriolis Effect

Shedding Light on the Sun and Earth

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...Show More
Following the Sun

Following the Sun

Shedding Light on the Sun and Earth

"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...Show More
Seasons

Seasons

Shedding Light on the Sun and Earth

In the first episode of this series, we briefly look at how the changing seasons affect life on our precious Earth and then examine what causes seasons, the turning of the days, and the three main climate zones.
Long Hot Summer Days

Long Hot Summer Days

Shedding Light on the Sun and Earth

In "Long Hot Summer Days" we explain why summer days are long and winter days are short, and how the length of daytime contributes to seasonal variations in temperature.
The Sun's Surface

The Sun's Surface

The Solar System

A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds. In a thermal decomposition reaction, heat is required to break the chemical bonds in the elements or...Show More
Causes of Aurora Borealis

Causes of Aurora Borealis

The Study of the Universe

This video explains which of the atmosphere's chemical components are responsible for the aurora borealis.
Causes of Lunar Eclipse

Causes of Lunar Eclipse

The Study of the Universe

On a full moon, when the Moon passes directly behind the Earth into its shadow, a lunar eclipse occurs. When the moon is entirely within the umbra, it causes a total lunar eclipse. When only a small part of the Moon’s surface is covered by the...Show More
Water Cycle

Water Cycle

Water Systems

The process in which water continuously changes its form through evaporation and condensation and circulates between the water bodies, the atmosphere, and land is known as the water cycle.
Impact of Melting Glaciers on Water Systems

Impact of Melting Glaciers on Water Systems

Water Systems

Glaciers and polar ice caps hold more than three - quarters of the Earth’s freshwater. Due to an overall increase in the global temperature, most glaciers in the world today are melting. This is, in turn, affecting the water systems, leading to...Show More
Rocky Shores and Reefs

Rocky Shores and Reefs

Life in the Sea

This programme looks at how rocky shores and shoreline reefs are formed, explains the three zones of a coastline, and examines the fauna and flora that live on on the coastline.
Wind Currents and Thunderstorms

Wind Currents and Thunderstorms

This video explains convection and global wind currents, and looks at the formation of thunderstorms.
Air Pollution

Air Pollution

This video defines and discusses human and natural pollutants of air and their sources.
Kessler Syndrome: What Happens When Satellites Collide

Kessler Syndrome: What Happens When Satellites Collide

Of all the man-made satellites in Low Earth Orbit, 95% are space junk: rocket thrusters, derelict satellites, and most of all, tiny fragments of debris from collisions and explosions. All this debris poses a potential threat to the future of...Show More
Phases of the Moon

Phases of the Moon

Miniclips

The Moon. We see it almost every night in the sky – but how much do we know about it? And why does it constantly change appearance? This incredible Miniclip animates all the phases of the Moon, including waxing, waning, full Moon, and new Moon,...Show More
Diving into the Water Cycle

Diving into the Water Cycle

Miniclips

The water that we drink today is the same water that the dinosaurs swam in and that people of ancient civilisations drank – and it’s all because of the wonderful water cycle! This Miniclip illustrates the stages involved in the water cycle,...Show More
The Movement of the Stars

The Movement of the Stars

Visible Stars

The Pole Star appears stationary because it lies on the axis of rotation of the Earth. The Earth rotates from west to east; hence the apparent movement of the stars is from east to west.
