Heat transfer

 

 

                                                  In this week I taught the chapter Heat to the 7th class students. Students learned the meaning of heat. Later I taught about methods of heat transfer i.e conduction, convection and radiation through the demonstration. I showed the process of conduction through the iron nail and by sticking the candle to the iron nail. Students observed the melting of the candle one by one. Later they learned the conductors and insulators of heat. They checked the different materials like iron, plastic and ice cream sticks. They checked whether they are conductors or insulators of heat. They got the clear idea about topic. Also they learned the convection method by holding the hands on the candle and beside the candle. Also they watched a video of convection process in water. Totally the students understand about heat very well and enjoyed the learnings.
