Lesson Plan version 1.1 PPT

1. take a small piece each of sodium and iron. Drop them into a 500 ml beaker containing water. What do you observe? Which reacts faster in water?

2. take a small piece of sodium in a spatula. Ignite it. Hold a piece of magnesium strip in tongs. Ignite it. What do you observe? Which burns very fast? Is colour of both the flames same? Sodium and magnesium are made up of atoms. Is the nature of both the atoms same? The above activities show that atoms of different elements have different properties.

Take precautions while conducting the above activities.
