Instructions

Activity - water cycle puzzle
• Enlarge and copy Natures Water Cycle (page 7) for each girl.
• Colour in the page and glue it to a piece of thin card
• Cut out puzzle shapes
• Discuss the different stages of the water cycle.

Evaporation - as water is heated by the sun, its surface molecules become energised, and break free, evaporating and rising as invisible vapour into the air.
• Transpiration - water vapour is also emitted from plant leaves by a process called transpiration.
• Condensation - as water vapour rises, it cools, and condenses, usually on tiny particles of dust in the air. When it condenses, it becomes a liquid again, or turns directly into a solid (ice, hail or snow). These water particles then collect and form clouds.
• Precipitation - rain, snow and hail are forms of precipitation that come from clouds. Clouds move around the world, pushed by wind. When they rise over mountain ranges, they cool, becoming wet so that water begins to fall as rain, snow, or hail, depending on the temperature of the surrounding air.
• Surface Runoff - water drains off by running across the land into creeks, ponds, lakes, and rivers that eventually take it back to the oceans.
• Percolation - surface water moves down, or percolates, through cracks, joints and pores in soil and rocks.
• Ground Water - much water is stored in the earth, occupying pores, cavities, cracks or other spaces in the rocks and soil.
• Water Table - the water table marks the change between the zone of aeration, and the
zone of saturation, in which water fills all the spaces in the soil and rocks.
