Grade 4 Science Vocabulary | 100 Fourth Grade Science Terms with Definitions, Examples & Practice

Grade 4 Science Vocabulary becomes easier when students learn the words as part of scientific ideas, investigations and explanations. This world-facing guide teaches 100 fourth grade science vocabulary words, Grade 4 science terms with definitions, science vocabulary worksheets, science word lists, matter vocabulary, energy vocabulary, force and motion terms, ecosystem words, plant vocabulary, Earth science terms, weather vocabulary and space vocabulary. Each term is explained in student-friendly language and connected to an example that shows how scientists actually use it.

Current Grade 4 science resources commonly organize vocabulary by topic—energy and motion, matter, ecosystems, Earth’s features, resources, rocks, plants, weather and investigation—and stronger materials ask learners to match definitions, apply words in real situations and use the terms in explanations rather than memorize flashcards alone.

This new page owns the Primary 4 / Grade 4 Science vocabulary search family inside the eduKateSG P4 world lane. It is additive: it does not replace the general Primary 4 vocabulary owner, the academic-verbs article, or any existing Science tuition page. Alicia, Tricia and Kai Kai are used to model the complete scientific-language loop: observe → name → measure → compare → explain → support with evidence → transfer the term to a new problem.

How to Learn Science Vocabulary Without Turning It Into Definitions Only

• Say the term and explain it in ordinary language.
• Identify the science idea or process it belongs to.
• Connect it to an observable example.
• Draw or imagine a simple representation when helpful.
• Use the term in a complete scientific sentence.
• Contrast it with a nearby term that could be confused.
• Retrieve the word from a definition after a delay.
• Use it in a new investigation, diagram or reading passage.
• Explain cause-and-effect relationships using the vocabulary.
• Check whether the term still makes sense outside the original lesson.

Parent Guide — Ask for the Example, Not Only the Definition

If a child says that friction is “a force that resists motion,” ask for two surfaces that would produce different amounts of friction and what the child predicts would happen. If the learner says evaporation is “liquid changing to gas,” ask where they have seen water disappear from a surface. Application reveals whether the definition is usable.

Teacher Guide — Science Vocabulary Is Concept Vocabulary

A child may pronounce and spell a term correctly while holding the wrong concept. That is why matching terms to definitions should be followed by application, diagrams, examples, non-examples and explanation. The most important repair is often conceptual rather than lexical.
