THE WEB OF ECOLOGICAL CONCEPTS: Eight Year Old / Third Grade
Yogesh Pathak
As discussed earlier, we believe that eight-year olds have the right background to learn material through two long ‘stories’ – essentially natural history and man-nature relationship history.
The story of evolution and biodiversity should cover the following concepts/clusters:
-
How old is the solar system and Earth? What was the Earth like before the formation of early life?
-
Theories of how living beings got created on Earth.
-
The key periods in Earth's history after life happened, and associated life forms (preliminary)
-
Evolution: concepts, preliminary
-
Fossils and their variety
-
Evolution of birds as a more detailed example
-
Examples of naturally extinct species: Dinosaurs
-
Evolution of man
-
Examples of extinction due to man’s interference: Mammoth and other large mammals
The story of man and nature’s relationship and human civilization should cover the following concepts/clusters:
-
Homo Sapiens’ journey from the branching of our species in the tree of evolution, while we were exclusively hunter gatherers.
-
Collaboration among Sapiens
-
Coexistence with other hominins (preliminary, with Neanderthals as an example)
-
Early diet
-
Language
-
Clans
-
Tools: Stone age and variety of tools from stones and animal bones
-
Fire and it’s many applications
-
Settlements and the role of water bodies
-
Cooking
-
Simple machines
-
Impact of settlements and the need for firewood on forests
-
Impact of hunting on other species like small mammals, large mammals, birds
-
Art and it’s evidence in caves
-
Relevant fossils and other artefacts found
-
Migration of Sapiens across the globe
-
Potential myths/religion among early tribes
-
-
Our journey from hunter-gatherers to farmers, pastoralists, and today’s industrialized mode of living
-
Start of goat/cattle herding and start of agriculture
-
Domestication of animals
-
Early villages, cities
-
Communities, tribes and their norms and rules
-
Trade
-
Specialization of skills and vocations
-
Early social stratification
-
Pottery
-
Early housing
-
Start of culture and religion
-
Start of chiefdoms and kingdoms
-
Evolution of arts including beads, painted pottery
-
Evolution of monetary commerce (preliminary)
-
Evolution of science (early, preliminary) and technology: Metal use – Copper, Bronze, Iron, Gold, Silver
-
Wheel and it’s applications
-
Early transportation: On land, rivers, oceans, snow
-
Larger civilization along major rivers: Preliminary. Some examples of dams, farming, and trade
-
Middle ages, role of military in sustaining kingdoms and empires: Impact on nature e.g. wood for navy, hunting of mammals, firewood needs - Preliminary
-
Modern scientific discoveries and inventions: A quick journey
-
Steam engines, electricity, jet engines, globalization, hyper transportation, hyper construction, variety of man-made materials, energy use, information technology: Preliminary, along with impact of nature like pollution and change in land use
-
-
Modern-day hunter gatherers, tribal societies and their co-existence with farmers, pastoralists, and the industrial man
In addition, the following concepts should be covered in this year
-
Basic geographic understanding of their vicinity, town, and county or district.
-
Interpreting the map of their town and district, filling various details in the map, etc.
-
Relate the physical/climatic conditions in the district to the modes of living, vocations, and socio-cultural aspects.
-
Concept of Ecosystem (Preliminary)
-
Natural landscape as a mosaic of ecosystems
-
Mapping natural landscape(s) into the map of town/district -- may not necessarily fit the map’s boundaries.
-
History of nature-man relationship to land, water, and forests (e.g. a river preceding human civilization, and human settlements happening along rivers) can be highlighted – mostly taking local examples from the district.
-
Story of evolution and story of man-nature relationship mapped on the local town/district
