Top 100 PSLE Vocabulary List | Engineering, Design & Invention Words for Grade 6

Top 100 PSLE Vocabulary List resources can help Grade 6 students understand how ideas become working objects and systems. This guide focuses on engineering vocabulary, design process words, invention vocabulary, structures, forces, machines, materials, electricity, manufacturing, robotics and technical communication.

Current elementary and middle-grade engineering resources commonly organise learning around a design process: define the problem, identify criteria and constraints, brainstorm, prototype, test, evaluate and improve. This article builds that search language into a complete upper-primary vocabulary system while keeping explanations practical and readable.

This child owns the Grade 6 engineering/design search job. It is distinct from the Science Investigation and Experiment list: science focuses on explaining and testing the natural world, while engineering focuses on designing solutions under requirements and constraints.

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 merely to recognise the word on this page; it is to use it correctly when the surrounding problem, text or situation changes.

Study ten terms at a time, then mix sections. Ask which words describe people, tools, systems, processes, evidence, decisions or outcomes. Build short cloze items and mini-scenarios. This makes the vocabulary easier to retrieve in unseen Grade 6 reading and writing tasks.

Design Process

1. engineering

Meaning: the use of science, mathematics and practical knowledge to design solutions to problems. Model: Alicia learned how engineering turns ideas into tested solutions. Engineering is a process as well as a field.

Context test: Cover engineering and read the sentence as a cloze item. Identify two clues that narrow the meaning: purpose, tool, action, structure, source, audience, process, risk or result. Predict the category before revealing the answer.

Precision test: Compare engineering with a neighbouring term. State one overlap and one boundary, then write a sentence where the neighbouring word would be less accurate. Precision prevents technical vocabulary from becoming a set of loose labels.

Reading transfer: Alicia writes a four-sentence Grade 6 passage containing engineering. Tricia underlines the clues that make the meaning recoverable. Kai Kai creates one plausible distractor and explains exactly which clue eliminates it. Rotate the roles.

Writing transfer: Use engineering 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 engineering aloud in twenty seconds without reading the definition. Then answer one follow-up beginning with how, why, what if, who uses this or what is the difference. If the explanation becomes circular, return to a concrete example.

Scenario test: Invent a realistic situation where engineering matters. Change one condition so another term becomes more accurate. Explain the switch and identify the clue that changed the answer. Engineering is a process as well as a field.

Delayed retrieval: Two days later, retrieve the word from the meaning, the meaning from the word and a fresh example from memory. Mix it with older vocabulary so page position cannot help.

Context test: Cover safety and read the sentence as a cloze item. Identify two clues that narrow the meaning: purpose, tool, action, structure, source, audience, process, risk or result. Predict the category before revealing the answer.

Precision test: Compare safety with a neighbouring term. State one overlap and one boundary, then write a sentence where the neighbouring word would be less accurate. Precision prevents technical vocabulary from becoming a set of loose labels.

Reading transfer: Alicia writes a four-sentence Grade 6 passage containing safety. Tricia underlines the clues that make the meaning recoverable. Kai Kai creates one plausible distractor and explains exactly which clue eliminates it. Rotate the roles.

Writing transfer: Use safety 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 safety aloud in twenty seconds without reading the definition. Then answer one follow-up beginning with how, why, what if, who uses this or what is the difference. If the explanation becomes circular, return to a concrete example.

Scenario test: Invent a realistic situation where safety matters. Change one condition so another term becomes more accurate. Explain the switch and identify the clue that changed the answer. Safety is a core engineering requirement.
