SUMMARY
This discussion focuses on simple experiments to demonstrate convection in a classroom setting. Key methods include using potassium permanganate crystals in a glass tube to visualize convection currents in water and a beaker setup with a candle and smoke to illustrate air convection. The potassium permanganate method involves heating the corner of a beaker to activate the crystals, while the candle experiment uses smoke to show airflow patterns. These experiments are effective for teaching the principles of convection clearly and engagingly.
