Lake Poso

Lake Poso 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 Lake Poso rather than just read about it. In short: Lake Poso (Indonesian: Danau Poso) is a lake in Central Sulawesi, Indonesia, and the third-deepest lake in Indonesia. The town of Pendolo is situated at the southern end of the lake, the town of Tentena is located at the northern end, while a number of smaller villages dot the shoreline.

Key takeaways

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

Reference excerpt

Lake Poso (Indonesian: Danau Poso) is a lake in Central Sulawesi, Indonesia, and the third-deepest lake in Indonesia. The town of Pendolo is situated at the southern end of the lake, the town of Tentena is located at the northern end, while a number of smaller villages dot the shoreline. The lake drains into the Poso River at Tentena, which flows into the Molucca Sea at the town of Poso.

Ecology The lake contains various fish, including the eel Anguilla marmorata which migrates between the lake and the sea, and 11 fish species that are endemic to the lake, notably buntingi ricefish (Adrianichthys, Oryzias nebulosus, O. nigrimas and O. orthognathus), gobies (Mugilogobius amadi and M. sarasinorum), and the halfbeak Nomorhamphus celebensis. These endemics are all highly threatened; in some cases possibly already extinct. One of the reasons for the drastic decline of the native fish are introduced, non-native species, particularly Mozambique tilapia and common carp. There is also a large number of endemic Tylomelania freshwater snails in the lake, as well as 11 endemic Caridina shrimps and Parathelphusid crabs (genera Migmathelphusa, Parathelphusa and Sundathelphusa). A park containing wild orchids is located near the village Bancea on the lake. As well the forests surrounding the lake still provide rare sightings of the anoa (dwarf buffalo) and the babirusa (literally, pigdeer), a ruminant pig. These two endangered species are among a number of wildlife species found only on the island of Sulawesi.

Worked examples

Example 1 — a first encounter with Lake Poso

Start with the simplest possible case. Write down what Lake Poso 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 Lake Poso 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 Lake Poso 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 Lake Poso

In research: Lake Poso 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 Lake Poso 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: Lake Poso is common in secondary-school and first-year university syllabi. It links to neighbouring topics Freshwater ecoregions, Lakes of Sulawesi, Landforms of Central Sulawesi, so understanding it makes those chapters shorter.
In everyday life: Look for Lake Poso 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.
