“Give the pupils something to do, not something to learn; and the doing is of such a nature as to demand thinking; learning naturally results.” – John Dewey
The Classes II and III members of the Spectrum club had loads of fun doing various demonstrations during their weekly club classes. On Saturday, July 25, 2020, the members learnt about Surface Tension, through experiments. They used water, pepper powder, dish wash liquid, milk and different food colors. They got the conclusion that liquid dish soap is mostly surfactants and it can easily lower the surface tension of water with pepper powder as well as can make the swirl of colors in the milk.
During their weekly club classes on Saturday August 1, 2020, the students conducted two different experiments, “Reaction with baking soda” and “Dancing popcorn”. For a child, it almost seems like magic with popcorn kernels bouncing up and down dancing in water. But dancing popcorn is actually a great learning activity with lots of scientific principles at work.
On Saturday, August 8, 2020, the members discussed on Static Electricity through an interesting experiment. The children cut a paper into pieces, rubbed a balloon on their hair or wool. After some time the pieces of paper got attracted to the balloon due to static electricity. Another experiment was also conducted using eraser, pen’s refill, a piece of paper, wool, scale or pen. When the scale was rubbed with wool and shown to the piece of paper it started to show movement due to the same phenomena. Children learnt many things about static electricity and enjoyed the class thoroughly.
