Science and technology used in transportation
There are multiple uses of convex and concave mirrors. One of the important use of convex mirror is this type of mirror is used as side mirrors in scooters, cars and in other automobile. Convex mirrors can form images of object spread over a larger area. So, these help the drivers to see the traffic behind them.
Such information should be given to the students while teaching sub- topic convex and concave mirrors from chapter " Light" of class VII.
Science and technology used in manufacturing process
In chapter "Fibre to fabric" of class VII, there is a process of converting fibres to wool. So while explaining that process students should be told about the latest machineries used in factories which involves less manual labour in converting fibre to wool. Machineries used in industries should be shown to the students through videos.
Science and technology in information and communication
While explaining the lesson "Sunita in space" class V, the students should be told about the satellite and their specific job. The different functions of satellite like to monitor cloud paterns for a weather station, to send television signals for t.v. etc.
Science, Energy and power technology
The conventional sources of energy are generally non renewable sources og energy, which are being used since a long time. the coal, petroleum, natural gas and electricity arw conventional sources of energy. so while explaining the lesson "conventional sources of energy" class IX, the students should be told how these fossil fuels like coal, petroleum can be used in thermal power plant where in fuel is burnt to produce heat energy ehich is converted into electrical energy. videos should be shown to the students for better understanding.
