Pupil outcome: I can identify the part played by evaporation and condensation in the water cycle. Key learning points: - Water doesn’t leave Earth’s atmosphere. It moves around in what is called the water cycle. - Water evaporates from...

Pupil outcome: I can observe water change from the liquid state to the gas state. Key learning points: - Water in the liquid state can change into water in the gas state (water vapour). - In its gas state, water is invisible, can flow,...

This video is explaining how water cycle works for kids.

NASA's Juno probe is coming to the end of a fantastic mission, but it's still got some tricks up its sleeve yet.

Any gas in the atmosphere that absorbs and re-emits radiation in the infra-red range, so warming the atmosphere and planet's surface.

All water on planet Earth is constantly cycled from the atmosphere, into reservoirs, and through plants and animals. The Earth's water has completed this cycle around 8 million times. Earth Science - Weather - Learning Points. Water on...

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...

How do the clouds closest to the Earth affect our weather? How are they formed and what do they look like? Earth Science - Weather - Learning Points. Temperature, humidity and air pressure produce ten different types of cloud. Those at...

Rain is essential to our planet. Without it, all life on Earth would struggle to survive. How do rain clouds form and what determines whether it rains or not? Earth Science - Weather - Learning Points. Rainfall comes from the clouds...

We use filtration and evaporation to separate out a mixture of water, sand and salt. The sand is removed using filtration, as it did not dissolve in the water. The remaining solution is heated until the water evaporates, leaving behind...

We use distillation to remove the water from ink. The ink is heated in a conical flask with a delivery tube running to a beaker. The water has a lower boiling point and so it evaporates before the ink. The water condenses as it travels...

We create a cloud in a bottle using warm water and smoke. Some warm water is placed in a plastic bottle and then some smoke is drawn in using a glowing splint. The bottle is sealed and then squeezed and released. The change in pressure...

We use a Hero's engine model to show how equal and opposite forces can cause propulsion. Two holes are pierced in a metal bottle and some water is added. This is suspended above a Bunsen burner, and as the water boils and leaves the...

We demonstrate the effects of imbalances of pressure. A metal can is crushed by atmospheric pressure. We add some water to a can and boil it until the can is full of water vapour. It is then sealed and left to cool and after a few...

What are the different types of clouds in the upper region of the troposphere? What do they look like and how are they are formed? Earth Science - Weather - Learning Points. High-level clouds are found between the Troposphere and the...

A blizzard creates a blanket of snow. Look closer and the true beauty of individual snowflakes can be seen. How are different shapes of snowflakes formed and why are they always perfectly symmetrical? Chemistry - Atoms And Bonding -...

The same water has been on Earth for four and a half billion years. Where did this water come from? Earth Science - Weather - Learning Points. 4.5 billion years ago, the Earth's surface was too hot for water to exist. Inside the Earth's...
