Show The steps for Experiment:- On Force of Nature [Tornadoes, Clouds, Water Cycle]
Objective:
To understand the forces of nature like twisters and typhoons and to learn about evaporation and cloud formation, how rainfall occurs and water cycle.
Requirements:-
Scale, Disposable plates, Cardboard, Contruction Paper, Sponage, Pet Bottles, Wax Crayon, Tumblers, Glass, Tape, Glass jar, Torch, Matches, Ice cubes, Edible colour and Alcohol thermometer.
1. Experiment/Procedure.
Adult supervision is required for this Experiment as dealing with hot water.
Take to clear tumblers and add a drop or two of edible colour to one of the tumblers and fill it with hot water to the brim. Fill the second tumbler up to the brim with cold water.
