Year 6 Science vocabulary list featuring Taxonomy and Micro-organism definitions to support classification mastery and literacy development across the primary curriculum.
A structured glossary of key Tier 2 and Tier 3 vocabulary with definitions and contextual example sentences, designed to close the vocabulary gap.
Subject: Science | Year: 6
Name: _________________________ Class/Set: ____________ Date: ____________
| Word | Definition | Example Sentence |
|---|---|---|
| Classification | The process of grouping living things based on their similarities and differences. | Scientists use classification to help them identify and study different animals. |
| Organism | An individual living thing, such as an animal, plant, or single-celled life form. | Every single organism in the pond plays a part in the local ecosystem. |
| Micro-organism | A living thing that is so small it can only be seen with a microscope. | Some types of micro-organism, like yeast, are very helpful in food production. |
| Vertebrate | An animal that has a backbone or spinal column. | A human is a type of vertebrate because we have a skeleton inside our bodies. |
| Invertebrate | An animal that does not have a backbone. | An earthworm is a common invertebrate found in school gardens. |
| Taxonomy | The scientific study of how living things are classified. | Carl Linnaeus is famous for his work in taxonomy and the way we name species. |
| Species | A group of similar organisms that can produce offspring together. | The tiger is a species of cat that is currently endangered in the wild. |
| Kingdom | One of the five main groups used to classify all living things. | All trees and flowers belong to the plant kingdom. |
| Fungi | Organisms such as mushrooms or mould that grow on decaying matter. | We found several types of fungi growing on the damp logs in the woods. |
| Bacteria | Tiny, single-celled organisms that can be found almost everywhere. | It is important to wash your hands to remove any harmful bacteria. |
Pedagogical Opportunities & Misconception Alerts 💡
Addressing the literacy gap in primary science requires moving beyond rote memorisation toward a structured understanding of biological hierarchies. By explicitly defining Taxonomy and the distinction between Vertebrate and Invertebrate organisms, the worksheet provides the necessary linguistic scaffolding to navigate complex classification keys. The structural layout of the vocabulary list employs a dual-column definition and contextual example format to reduce extraneous cognitive load, allowing pupils to focus on the semantic relationships between species and kingdoms. This systematic approach ensures Year 6 learners transition from intuitive grouping to formal scientific categorisation, securing the substantive knowledge required for secondary transition.
