Y5’s learnt about the Water Cycle today and we learnt that it is a never-ending cycle. We know that the water we have today, is the same water that’s been around with us over millions of years. That is because of the Water Cycle. We are now ready to conduct an experiment involving ‘gases’ and ‘evaporation’. One of the questions – at the start of the unit – was to know: How a liquid could be turned into a gas? [click on the above image for a larger view]
On this link you can watch an animation on the water cycle.
Precipitation is a vital component of how water moves through Earth’s water cycle, connecting the ocean, land, and atmosphere. Knowing where it rains, how much it rains and the character of the falling rain, snow or hail allows scientists to better understand precipitation’s impact on streams, rivers, surface run-off and groundwater. Frequent and detailed measurements help scientists make models of and determine changes in Earth’s water cycle.
The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. The water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it flows back into the oceans, where it will once more evaporate. The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth. A great link to follow up:
