Experiment Script 1: Identifying Subatomic Particles
Objective: To identify and understand the properties of subatomic particles - protons, neutrons, and electrons.
Materials Required: Model of an atom (3D model or chart), Positive and negative magnets, Balloons, and Sand.
Procedure:
Display the model of an atom and explain that it consists of three main subatomic partic...
Experiment Script 2: Thomson’s Model of Atom
Objective: To understand and visualize Thomson’s model of the atom.
Materials Required: Plasticine (clay), Small beads or marbles, A small plastic or glass sphere.
Procedure:
Take a small plastic or glass sphere and fill it with plasticine.
Insert the beads or marbles representing electrons inside the plasticine, showing that electrons are embedded in a positive charge sphere.
Explain the concept using the model.
Observation: The electrons are embedded like seeds in a watermelon.
Conclusion: Thomson’s model suggests that an atom is a positively charged sphere with negatively charged electrons embedded in it.
