A closer look at the three key processes that shape our coasts. What are they and what effects do they have? Earth Science - Geology - Learning Points. Our coastlines are constantly being re-shaped by three key processes. Erosion -...

The earth below our feet is continually moving. How do changes underground lead to effects on the surface, and what happens to change these movements into devastating earthquakes? Earth Science - Geology - Learning Points. Movement of...

Wave and tidal power are a developing form of renewable energy. How do they work and what makes them desirable alternatives to other forms of renewable energy? Earth Science - Earth's Resources - Learning Points. The Atlantic Ocean and...

It can take years before our limbs and brain work together well enough to achieve good balance. What role do our ears play in helping us to meet this incredible challenge? Biology - Being Human - Learning Points. Our sense of balance is...

Salt was discovered thousands of years ago as a way of preserving food. How does it do this? And what else does salt preserve? Chemistry - Chemical Industries - Learning Points. Food rots because of bacteria and fungi. Salt is an...

What is the difference between day and night? How is this governed by the Earth's movement? Physics - Our Solar System - Learning Points. The Sun generates light. The Earth spins on its axis. A full rotation of Earth takes 24 hours. The...

The ingenious system to measure the distance to the Moon involving Apollo astronauts, lasers and a unique mirror system planted on the lunar surface. Physics - Our Solar System - Learning Points. In 1969, the Apollo 11 astronauts left an...

Wind power is a clean and renewable energy source. But problems associated with this form of energy mean wind power currently only generates a tiny percentage of our electricity. Earth Science - Earth's Resources - Learning Points. Wind...

Plants have developed an array of chemical, mechanical and mimicry methods to fight off predators, meaning that they are not as defenceless as they seem. Biology - Plants - Learning Points. Plants have evolved defence mechanisms to ward...

How our ears hear different frequencies, and how they work with the brain to turn these into sounds which we understand. Biology - Being Human - Learning Points. Sounds are simply movements of air molecules. Our ears are extremely...

An introduction to joint movements, including hinge, ball-and-socket and pivot joints. Biology - Human Body - Learning Points. There are three types of moveable, or synovial, joints within the skeleton. Hinge joints allow movement in one...

Our thumbs are complex instruments; we need big brains to control them. Are they the reason behind the evolution of superior human intelligence? Biology - Human Body - Learning Points. The evolution of our hands and our large brains are...

Lasers are usually associated with heat. But scientists have instead used them to reach the coldest temperature ever recorded. Could they reach absolute zero? Physics - Energy And Radioactivity - Learning Points. Absolute zero is...

The weather systems on our planet are all driven by one thing: air. Discover how our weather is driven by energy from the Sun, affecting the movement of air. Earth Science - Weather - Learning Points. Our weather is a chaotic and complex...

What is the difference between solids, liquids and gases? How does each state behave? Chemistry - Atoms And Bonding - Learning Points. The kinetic theory of matter states that particles are in constant motion and there are forces of...

Everything we eat contains calories. We need them to function and carry out everyday tasks. How do we know which foods are right to eat and which contain 'empty calories'? Chemistry - Chemical Industries - Learning Points. Calories are...

Animals share many of our senses, but can use them in very different ways. Snakes, bats and cheetahs have senses optimised for hunting and migrating in different environments. Biology - Being Human - Learning Points. Different sensory...

Isaac Newton's Laws of Motion explain how and why objects move as they do - the principles which underlie all of modern mechanics. Physics - Forces - Learning Points. Sir Isaac Newton published his laws of motion in 1687. Every movement...
