Objective: To teach the students about atoms and its structure
Subtopics to be covered:
- Dalton's Atomic Theory
-Atomic and Mass numbers
- Electronic configuration
Learning Outcome:
- Students know about the structure and characteristics of proton/neutron/electron
- They know about various shells of an atom and how to calculate the maximum number of electrons in a shell
-They know about the elctronic configuration of a few elements

1. In your village, visit a place that has a fence of wire. Take few small marbles or pebbles along with you. Throw them all in one go into the fence. You will observe that few of the pebbles will pass through the fence to the other side, and few will get hit and bounce back. This is how the electrons also move.
