Objective: To educate the children about metals and non metals and their physical and chemical properties
Subtopics to be covered:
- Properties of Metals and Nonmetals
- Reaction with acids, bases, water, Displacement reactions
- Uses of metals and non metals, metalloids
Learning Outcome:
- Students can tell what happens when a metal/non metal reacts with acids/bases etc.
- They can name metals and non metals found in our day-to-day life.
- Students are familiar with the terms lustrous, malleability, sonorous, ductility and can classify materials based on these properties
