Old Copper complex

Old Copper complex is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Old Copper complex rather than just read about it. In short: The Old Copper complex or Old Copper culture is an archaeological culture from the Archaic period of North America's Great Lakes region. Artifacts from some of these sites have been dated from 6500 to 1580 BCE.

Key takeaways

Old Copper complex belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Old Copper complex to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Old Copper complex from memory before moving on to harder problems.

Reference excerpt

The Old Copper complex or Old Copper culture is an archaeological culture from the Archaic period of North America's Great Lakes region. Artifacts from some of these sites have been dated from 6500 to 1580 BCE. It is characterized by widespread copper artifacts, including tools and weapons, as well as ornamental objects.

Western Great Lakes The Old Copper complex of the Western Great Lakes is the best known, and can be dated to around 6,500 BCE. Great Lakes natives of the Archaic period located 99% pure copper near Lake Superior, in veins touching the surface and in nuggets from gravel beds. Major quarries were located on Isle Royale, the Keweenaw Peninsula, and the Brule River, and copper was deposited elsewhere by glaciation as well. By heating, annealing and hammering, these cultures worked the copper into shape and produced a variety of spearpoints, tools and decorative objects. In addition to their own use, the Copper Complex peoples traded copper goods for other exotic materials. By about 1,000 BCE, copper was increasingly restricted to jewelry and other status-related items, rather than tools. This is thought to represent the development of more complex social hierarchies in the area. The Copper Culture State Park, in Oconto, northeastern Wisconsin, contains an ancient burial ground used by the Old Copper complex culture between around 4,000 and 2,000 BCE.. It was rediscovered in June 1952 by a 13-year-old boy who unearthed human bones while playing in an old quarry. By July the first archaeological dig was started by the Wisconsin Archaeological Survey.

Worked examples

Example 1 — a first encounter with Old Copper complex

Start with the simplest possible case. Write down what Old Copper complex claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Old Copper complex before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Old Copper complex ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Old Copper complex

In research: Old Copper complex appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Old Copper complex in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Old Copper complex is common in secondary-school and first-year university syllabi. It links to neighbouring topics Archaeological cultures in Ontario, Archaeological cultures of North America, Archaeology of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Old Copper complex outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
