Electric Heater Model



                                                                              Today  I conducted a tactivity Electric heater model for 7th class. Through this students understand electrical energy is converted into heat and this can be used for coocking. Students enjoyed this water becoming hot. Students increased the number of cells to get water more hot and to get it very fast. First they assumed what happens in the temperature with respect to time. After that they observed & note down the variation of temperature with time.
