Objective: To teach the students about various physical and chemical changes that happen around us
Subtopics to be covered:
- Difference between physical change and chemical change
- Crystallisation
- Galvanisation
Learning Outcome:
- Students can classify the processes into physical and chemical changes happening around them
- They know how iron rusts

1. Cut a piece of paper in four square pieces. Cut each square piece further into four square pieces. Keep these pieces on the floor or a table so that the pieces acquire the shape of the original piece of
paper.Can you join the pieces back to make the original piece? Is there a change in the property of the paper?
2.Group students to play this game:
a) Let one name a common process (eg: rusting of iron)
b) The other will decide if it is a physical or chemical change. The second student an now pick another and name another process. continue...
