Top 100 PSLE Vocabulary List resources can help Grade 6 students understand the water cycle, freshwater, rivers, groundwater, watersheds, water quality, water treatment and water conservation. Current Grade 6 resources repeatedly foreground evaporation, condensation, precipitation, runoff, infiltration, groundwater, aquifer, transpiration and watershed, making this a strong standalone search and learning job.
This guide expands those familiar water-cycle words into a connected system. Students move from atmospheric processes into rivers and lakes, underground water, drainage basins, water quality, treatment, field measurement and water-resource risk. That broader network makes the vocabulary useful in science, geography, comprehension and informational writing.
This child is narrower than the Environment, Climate and Sustainability list. Environment owns broad ecological and climate systems; this page owns freshwater movement, storage, quality, measurement and human use.
How to Use This Top 100 List
Alicia, Tricia and Kai Kai use this page as an active vocabulary system rather than a glossary. Each term is learned through definition, context, contrast, transfer, oral explanation and delayed retrieval. The goal is not merely to recognise a word on this page, but to use it accurately when the surrounding Grade 6 text, diagram, experiment or explanation changes.
Study ten terms at a time, then mix categories. Ask which words describe processes, structures, measurements, locations, evidence, causes or results. Build short cloze passages and compare neighbouring terms. This helps the learner organise a scientific vocabulary network instead of memorising isolated labels.
Water Cycle Processes
1. water cycle
Meaning: the continuous movement of water through Earth’s atmosphere, land, living things and water bodies. Model: Alicia drew arrows to show the water cycle. The cycle has no single starting point.
Context test: Cover water cycle and read the model as a cloze sentence. Identify at least two clues that narrow the meaning: process, location, movement, measurement, cause, result, material or relationship. Predict the category before revealing the answer.
Precision test: Compare water cycle with a nearby term from this section. State one overlap and one important boundary. Then write a sentence in which the neighbouring term would be inaccurate. This prevents a group of technical words from becoming interchangeable in the learner’s mind.
Reading transfer: Alicia writes a four-sentence Grade 6 passage containing water cycle. Tricia underlines the clues that make the meaning recoverable. Kai Kai creates one plausible distractor and explains exactly which clue eliminates it. Then the roles rotate.
Writing transfer: Use water cycle in a fresh explanatory paragraph. Add one natural collocation and one cause, effect, comparison, measurement or example. The term should make the science clearer rather than simply make the sentence sound technical.
Oral transfer: Explain water cycle aloud in twenty seconds without reading the definition. Then answer one follow-up beginning with how, why, where, what changes or what is the difference. If the explanation becomes circular, return to a concrete example.
Scenario test: Invent a realistic or scientific situation where water cycle matters. Change one condition so a related term becomes more accurate. Explain the switch and identify the clue that changed the answer. The cycle has no single starting point.
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.

Reading transfer: Alicia writes a four-sentence Grade 6 passage containing depth. Tricia underlines the clues that make the meaning recoverable. Kai Kai creates one plausible distractor and explains exactly which clue eliminates it. Then the roles rotate.
Writing transfer: Use depth in a fresh explanatory paragraph. Add one natural collocation and one cause, effect, comparison, measurement or example. The term should make the science clearer rather than simply make the sentence sound technical.
Oral transfer: Explain depth aloud in twenty seconds without reading the definition. Then answer one follow-up beginning with how, why, where, what changes or what is the difference. If the explanation becomes circular, return to a concrete example.
Scenario test: Invent a realistic or scientific situation where depth matters. Change one condition so a related term becomes more accurate. Explain the switch and identify the clue that changed the answer. Depth changes across a channel.
