Top 100 PSLE Vocabulary List | Science Investigation & Experiment Words for Grade 6

Top 100 PSLE Vocabulary List resources can strengthen both English comprehension and scientific literacy. This guide focuses on Grade 6 science vocabulary, scientific method words, experiment vocabulary, investigation terms, variables, measurement, data and laboratory language. The one hundred terms explain how students ask questions, design fair tests, collect evidence, analyse results and evaluate conclusions.

Current Grade 6 science resources commonly foreground vocabulary such as observation, hypothesis, variables, data, measurement, evidence and scientific method because students need the language before they can explain the reasoning. This page keeps the search job at upper-primary level and does not compete with eduKateSG’s Secondary 1 science vocabulary owner.

The article is world-facing rather than syllabus-locked. It supports informational reading, science passages, cross-curricular English and clear explanation. When a question uses a command such as identify, compare, explain or evaluate, students can connect this science list to the Academic Verbs and Question Command Words list.

How to Use This Science Vocabulary List

Alicia, Tricia and Kai Kai study science words as part of reasoning. Every term should help them observe, measure, compare, explain or evaluate something. Definitions matter, but the stronger test is whether the learner can place the term inside a scientific question, method, result or conclusion without misusing it.

Scientific Inquiry

1. observation

Meaning: information noticed carefully using senses or instruments. Model: Alicia recorded an observation about the colour change. Observation describes what is detected before explaining why.

Context test: Remove observation and ask which clues remain: measurement, equipment, cause, result, comparison or investigation step. Predict the type of concept before revealing the word. This trains scientific reading as well as vocabulary.

Precision test: Compare observation with a related science term. State one important boundary. For example, observation differs from inference, accuracy from precision, and heat from temperature. Then write a sentence where the neighbouring term would be wrong.

Investigation transfer: Alicia designs a simple investigation where observation matters. Tricia identifies the step or evidence. Kai Kai checks whether the term has been used in the right scientific sense. Rotate roles so every learner moves between vocabulary and method.

Reading transfer: Place observation inside a four-sentence Grade 6 science passage. Add enough context for another learner to infer the meaning. Then create one distractor and explain which clue rules it out.

Explanation transfer: Use observation in a two-sentence scientific explanation. The first sentence states an observation or result; the second uses the term to explain, compare or evaluate it. Avoid using technical vocabulary without a clear relationship to the evidence.

Oral transfer: Explain observation aloud in twenty seconds, then answer one follow-up beginning with how would you measure, why does this matter, what is the difference or what would make this test fairer. This reveals whether the vocabulary is connected to scientific thinking.

Delayed retrieval: Return after two days. Write the term from the definition, then give a new example from a different science topic. Observation describes what is detected before explaining why. If the word only works in the original model, keep practising transfer.
