Top 100 PSLE Vocabulary List resources can help Grade 6 students read about oceans, coasts, marine life, tides, waves, coral reefs, ocean currents, seafloor features and marine conservation. This guide builds a complete upper-primary marine vocabulary system for science, geography, comprehension and composition.
Ocean vocabulary often appears across several school subjects: geography names coasts and seafloor features, science explains marine organisms and adaptations, and environmental reading discusses pollution, overfishing and conservation. This article brings those connected terms together at one Grade 6 level instead of scattering them across unrelated lists.
This child is deliberately narrower than the Environment, Climate and Sustainability list. Environment owns broad planetary systems; this page owns the ocean system itself—water movement, coastal landforms, marine organisms, adaptations, human impacts and research.
How to Use This Top 100 List
Alicia, Tricia and Kai Kai use this page as an active vocabulary system. Each term is learned through definition, context, contrast, transfer, oral explanation and delayed retrieval. The goal is not simply to recognise the word on the page; it is to understand how the concept works and use the vocabulary accurately in a new Grade 6 reading or writing task.
Study ten terms at a time, then mix sections. Ask which words name structures, processes, locations, measurements, relationships, tools or changes. Build short cloze passages and compare neighbouring terms. This helps the learner move from memorised labels towards a connected knowledge network.
Ocean Foundations
1. ocean
Meaning: a vast body of salt water covering most of Earth’s surface. Model: The Pacific is the largest ocean. Oceans are connected.
Context test: Cover ocean and read the sentence as a cloze item. Identify two clues that narrow the meaning: structure, function, process, location, cause, result or relationship. Predict the category before revealing the answer.
Precision test: Compare ocean with a nearby term from the same section. State one overlap and one important boundary. Then write a sentence where the neighbouring word would be inaccurate. This trains precise scientific language rather than loose synonym use.
Reading transfer: Alicia writes a four-sentence Grade 6 informational passage containing ocean. Tricia underlines the clues that make the meaning recoverable. Kai Kai proposes one plausible distractor and explains exactly which clue removes it. Then the roles rotate.
Writing transfer: Use ocean in a fresh explanatory paragraph. Add one natural collocation and one cause, effect, comparison or example. The word should help the reader understand the system rather than merely make the sentence sound technical.
Oral transfer: Explain ocean aloud in twenty seconds without reading the definition. Then answer one follow-up beginning with how, why, where, what happens next or what is the difference. If the explanation becomes circular, return to a concrete example.
Scenario test: Invent a realistic or scientific situation where ocean matters. Change one condition so a related term becomes more accurate. Explain the switch and name the clue that changed the answer. Oceans are connected.
Delayed retrieval: Two days later, retrieve the term from its definition, the definition from the term and a new example from memory. Mix it with older vocabulary so page order cannot provide the answer.

Meaning: loss of symbiotic algae from stressed coral, causing pale colour. Model: Heat stress triggered coral bleaching. Bleached coral can sometimes recover.
Context test: Cover coral bleaching and read the sentence as a cloze item. Identify two clues that narrow the meaning: structure, function, process, location, cause, result or relationship. Predict the category before revealing the answer.
Precision test: Compare coral bleaching with a nearby term from the same section. State one overlap and one important boundary. Then write a sentence where the neighbouring word would be inaccurate. This trains precise scientific language rather than loose synonym use.
Reading transfer: Alicia writes a four-sentence Grade 6 informational passage containing coral bleaching. Tricia underlines the clues that make the meaning recoverable. Kai Kai proposes one plausible distractor and explains exactly which clue removes it. Then the roles rotate.
