The children were made to do three major experiments. They were to make a number of smokeless chulhas and calculate their relative efficiencies through water boiling tests and finally they do full-fledged cooking experiments by cooking the necessary “balanced food” for the camp. The chulha was made a point of departure to interesting concepts like burning, components of smoke, imperfect burning, effect on health, chemical and physical changes, exothermic and endothermic reactions, rate of reaction, the principle of pressure cooker and insulated box, effect of heat on solids, liquids and gases, the functioning of a chimney, heat conduction, convection and radiation, advantages of improved burning and efficiency, scarcity of firewood, the economy and ecology of firewood,various sources of energy, etc.. The water boiling test was used to acquaint the children with the idea of a scientific experiment - how to design and conduct it, how to observe, how to measure, how to make inferences and how to grasp the sources of errors. The cooking experiment was a point of departure for biology: balanced food, human body, its different parts, sources of all food, photosynthesis, efforts to increase photosynthetic efficiency and thus leading to frontiers in molecular biology. The idea was to convince the teacher that there could be any number of points of departure and he/she could teach all the curriculum in life-related and inter-related ways, without the conventional compartmentalisation into physics, chemistry biology, etc.. In a later experiment, seeds were made the point of departure and in yet another one, it was the wheel.
