Homestead (meteorite)

Homestead (meteorite) is a earth 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 Homestead (meteorite) rather than just read about it. In short: Homestead is a L5 meteorite fallen on 12 February 1875 in Iowa, United States, first described by Gustavus Detlef Hinrichs. Sometimes called the Amana meteorite because of the nearby Amana Colonies it was called the Homestead meteorite, because Homestead, Iowa was the nearest train station.

Key takeaways

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

Reference excerpt

Homestead is a L5 meteorite fallen on 12 February 1875 in Iowa, United States, first described by Gustavus Detlef Hinrichs. Sometimes called the Amana meteorite because of the nearby Amana Colonies it was called the Homestead meteorite, because Homestead, Iowa was the nearest train station. The Amana meteorites also include a large meteorite fallen in May 1879.

History On the evening of 12 February 1875 above Iowa a brilliant fireball was observed. It produced a variety of rumbling sounds and detonations, which shook houses "as if moved by an earthquake". About 100 meteorite fragments fell over a 18-square-mile (47 km2) snowy countryside area from Amana to Boltonville in Iowa County. The first found fragment, a stone weighing about 3.5 kilograms (7.7 lb), was discovered by Sarah Sherlock 3 kilometres (1.9 mi) south of Homestead. The area was wooded and covered by snow, impeding recovery efforts. On 10 February a 40 centimetres (16 in) snowfall blanketed the ground, preventing the great majority of the fragments from being discovered until spring. The 74 pounds (34 kg) main mass was found along with a 48 pounds (22 kg) fragment buried 2 feet (0.61 m) in the soil. The meteorite made international news. Gustavus Detlef Hinrichs, a natural scientist from the University of Iowa reported about it in Popular Science Monthly in 1875. As of December 2011, approximately 230 kilograms (510 lb) has been found. The meteorite has brought "a small fortune" to the Amana area, as pieces were sold for a day s wage per pound at the time and added to collections in the US and Europe.

1879 The Amana meteorites also include a large meteorite fallen in Estherville, Iowa on May 10, 1879. Its largest piece weighed 437 pounds and buried 14 feet deep into a farm field. It is the largest witnessed meteorite in North America. The largest piece can be visited at the Estherville Meteorite Center, in downtown Estherville.

Composition and classification It is a L5 type ordinary chondrite. It is also brecciated and veined.

Worked examples

Example 1 — a first encounter with Homestead (meteorite)

Start with the simplest possible case. Write down what Homestead (meteorite) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Homestead (meteorite) 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 Homestead (meteorite) 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 Homestead (meteorite)

In research: Homestead (meteorite) appears in earth 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 Homestead (meteorite) 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: Homestead (meteorite) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1875 in Iowa, 1875 in science, Chondrite meteorites, so understanding it makes those chapters shorter.
In everyday life: Look for Homestead (meteorite) 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.
