Science Experiences – siphon system and an electroscope experiment performed by students

Devarshi Sharma of Class X C (DS) has made a Siphon System for moving coloured water

Trishit Ghosh of Class X C (DS) has made an electroscope to show the existence and nature of charge. He saw that when silicon rod was rubbed with microfiber cloth, a charge developed in both silicon and macrofibre cloth as the leaves were in diverged condition. The charges which were generated in the cloth and silicon were mutually opposite in nature, as the leaves were attracted to each other.
