Do plants contribute to the Water Cycle?
You got it! Plants and trees also produce water vapour through transpiration. It’s the process by which plants lose water through their leaves. This water floats into the atmosphere and eventually becomes precipitation as well. I guess we can say that transpiration helps evaporation to get the water back in to the atmosphere. Activity: • Boil Water in a kettle to represent the sun evaporating from the sea and rivers • Position a cold tile in the steam; the water vapour will cool and condense into “raindrops”. • Collect the water in a cup “Sweating Plant” • Place a transparent plastic bag over a busy plant – tie the bag tightly – and leave it outside in warm air. After a few hours water vapour transpiring from the plant will appear as droplets within the bag. Activities teachers can conduct with their students: • Stubborn Stan says “Guyana is the land of many waters; I don’t have to worry about how I use it!” Think of 5 things that you would say to Stubborn Stan about his attitude towar
