This term our Inquiry topic is focused on the concept of “Sustainability.” Our unit is leading children to uncover some of the incredible changes of the earth over time. We will be looking at global warming, climate change and natural disasters and their effects on our planet.
- Students have been exploring how a natural disaster is the consequence of the combination of a natural hazard (a physical event like a volcanic eruption, typhoon, tropical cyclone, tornado an earthquake, a landslide or a tsunami) and human activities.
- drawn a detailed and labelled a diagram of a particular natural disaster to show the process the land and environment goes through during the course of action.
- participated in a mapping activity in groups whereby they had to research and locate the areas around the world prone to certain natural disasters.
- been researching a recent natural disaster that has occurred in the world and are writing a summary on the main details surrounding their chosen disaster.
Some of the info the children have discovered so far are:
- Most natural disasters are caused by weather. Weather disasters can be caused by hurricanes, tornadoes, floods, tsunamis, thunderstorms, windstorms, wildfires, avalanches and blizzards.
- Earthquakes can occur both underground, on land and also under the water in the ocean.
- Earthquakes are the cause of other natural disasters such as volcanic eruptions and tsunamis.
- Earthquakes are not generally killers. The events afterwards are the cause of death including buildings collapsing, tsunamis and volcanoes.
- Nearly 90 percent of all volcanoes are in the “Ring of Fire,” a group of volcanoes that circle the Pacific Ocean.
- Cyclones, hurricanes and typhoons are the same thing. Different names are used in different parts of the world. In the Atlantic Ocean they are known as hurricanes, in the tropics they are known as tropical cyclones, in the Indian Ocean they are known as cyclones and in the Pacific Ocean they are known as typhoons.
- Worldwide in 2011, there were 154 floods, 16 droughts, and 15 cases of extreme temperature.
Over the past few decades, the frequency and impact of natural disasters have increased dramatically. Millions have been killed, billions have been affected, and the cost of damage has been immeasurable. But while we can’t change when, where or how often they occur, we can prepare for and minimize their impact.
