In honour of today being World Oceans Day, the post is about seasons on the oceans.
June is one of the months of peak storm activity over many of the world's oceans. Tropical storms have all ready occurred this year in both the northeast and the northwest Pacific Ocean and in the north Indian Ocean and the Bay of Bengal. The season is just beginning in the north Atlantic Ocean and the Gulf of Mexico. Worldwide, the number of tropical cyclones this year should peak in August or September. Many, many of the readers of this blog, and the children they are educating, live where tropical storms regularly come to shore. For most others, the big storms are enough a part of the news that even little children hear about them.
When a tropical storm becomes large and the winds reach a speed of about 120 km per hour, it is called a tropical cyclone, a hurricane or a typhoon. A number of factors are necessary for a tropical cyclone to form but one of the key ones is that the surface temperature of the water - for 50 meters down -- must be at least 26.5 degrees centigrade. That's warm. One of the main effects of tropical cyclones is to create great waves, which stir up the water, bringing up cooler waters and reducing the temperature. When they hit land, they bring enormous amounts of rain to land that is often parched. As with everything in nature, they are a part of a cycle. Yet, as everyone knows, these storms are violent and dangerous for most creatures on land. The high winds, great waves and flooding destroy buildings, leaving many people homeless.
It is important that children learn about these great storms without fear, but with curiosity when examining them as phenomena and with practicality when learning how to prepare for and survive them. If you are living in an area of such storms, the best websites for practical knowledge for children are given below. If you live far from where such storms occur, perhaps now is the time not only to teach children about them, but to encourage children to be involved in helping others who have suffered from them. Save the Children has excellent and trustworthy programmes of disaster relief to which a class might donate.
Tropical Cyclone Dance
This works best with a large group of children.
You will need enough pieces of A4 size paper for each child to have one, in three colours: black, white, grey.
Have three or four children, holding white paper, stand in a tight circle and shake their papers quietly. They are the eye of the hurricane.
Have a larger group of children, holding black paper, stand in one or two large circles around the eye, and shake their papers as noisily as possible. They are the thunderstorms that surround the eye.
Have the last group of children, holding grey paper, stand in a circle around the thunderstorm group, shaking their papers with a medium amount of noise. They are the rain bands.
Now, have the children in the thunderstorms and rain bands move, waving and shaking their papers, around the eye, which does not turn.
This has been done by a class in India with coloured scarves, making a very lovely presentation.
