• Photographs showing Central Park, Manhattan, United States of AmericaSuggested activity:Ask students to identify which season each photo depicts. From top left in a clockwise direction- Winter, spring, autumn, summer.Ask students which season Singapore is most likely to experience. SummerAsk them why Singapore does not experience the other three seasons. Location: Singapore is located in the Tropics, where temperatures are consistently high throughout the year; students will learn more under ‘Latitude’ in this GatewayFor NA students:Help them identify the seasons by observing the vegetation cover. In winter, there will be no vegetation cover, in autumn, it will be red; the vegetation cover is green in spring and summer, with more vegetation cover present in summer.For question on why Singapore does not experience other three seasons: you can use the world map to locate USA and Singapore to help the studentsImages: © Songquan Deng/Dreamstime.com and © Guter/Dreamstime.com
• For studentsAsk them what are the kind of weather they have experienced in Singapore for the past year. (Rainy, sunny)Question them why they did not experience the 4 seasons. (Different locations)Teacher to prompt them for examples and thereafter use map to show them it is generally based on latitudes.

6. 6. Comparison chartClimate WeatherDefinition:Describes the average conditions expected at a specificplace at a given time.A regions climate is generated by theclimate system, which has five components: atmosphere,hydrosphere, cryosphere, land surface, and biosphere.[1]Describes the atmospheric conditions at a specificplace at a specific point in time. Weather generallyrefers to day-to-day temperature and precipitationactivityComponents:Climate may include precipitation, temperature, humidity,sunshine, wind velocity, phenomena such as fog, frost, andhail storms over a long period of time.Weather includes sunshine, rain, cloud cover, winds,hail, snow, sleet, freezing rain, flooding, blizzards,ice storms, thunderstorms, steady rains from a coldfront or warm front, excessive heat, heat waves andmoreForecast: By aggregates of weather statistics over periods of 30 yearsBy collecting meteorological data, like airtemperature, pressure, humidity, solar radiation,wind speeds and direction etc.Determined by:Aggregating weather statistics over periods of 30 years("climate normals").Real-time measurements of atmospheric pressure,temperature, wind speed and direction, humidity,precipitation, cloud cover, and other variablesAbout:Climate is defined as statistical weather information thatdescribes the variation of weather at a given place for aspecified interval.Weather is the day-to-day state of the atmosphere,and its short-term (minutes to weeks) variationTime frame: Measured over a long period Measured for short termStudy: Climatology Meteorology6
