The questions below are the first stage in preparing an all-encompassing module in science. The topic of heat was chosen because heat is the life force of all existence.
The topic of heat was brainstormed to identify the widest possible range of questions on heat. This included the physiology of all life – plant and animal and the role of heat that comes from the sun. From heat sources come light.
We examine heat transfer, radiation of heat, the seasons, response of birds to the seasons, ocean currents, winds, rainfall, breeding of fish and marine plant life, volcanoes, tectonic plates, infra red and ultra violet radiation, heating in machinery, friction and heat from asteroids entering the earth’s atmosphere.
A science course based on heat could well be appropriate for students in primary and high schools of Papua New Guinea.
To make study relevant for students in village schools, we could choose those aspects of science that are relevant to village life. The early course could be based on these.
These would include rainfall, winds, plants, photosynthesis, volcanoes, cold at high altitudes, construction of houses on the coast and in the highlands, animals, birds and human beings keeping warm and heat rising in rotting vegetables.
We could include also causes of fever, heat in the bodies of reptiles and mammals, cold at night, global warming, mosquitoes moving into the high altitudes, plants growing to the sun, snakes and lizards sleeping on rocks in the mid-morning sun,
There could also be birds sitting on eggs, feathers to keep the birds warm, physical exertion producing increased body heat and heat in engines.
