Activity : Building the structure of atom









































 Learners of Class VIII performed activity of making model of structure of atom. Learners have been given five elements on the board. They have to calculate the number of protons, neutrons and electrons in each element with the help of atomic number and mass number. Then they took three different coloured beads or pulses representing electron, proton, neutron. Using compass and pencil they made shells in their activity file. Then they pasted correct counted no. of sub atomic particles. The activity makes them clear about the structure of atom.
