Reception Science: States of Matter Knowledge Organiser

Support scientific vocabulary and early understanding with this Reception states of matter knowledge organiser, designed to accompany our full Reception States of Matter science unit.

This child-friendly science reference tool introduces key concepts such as solids, liquids, melting, temperature and texture through clear visuals and simple explanations. It helps children revisit important vocabulary, discuss observations and build confidence when talking about materials and changes they notice in the world around them.

What is included in this Reception states of matter knowledge organiser?

• Key scientific vocabulary with EYFS-appropriate definitions
• Visual prompts to support understanding of solids, liquids and changing materials
• Examples linked to everyday objects and familiar experiences
• Scientific enquiry prompts focused on observation, comparison and discussion
• Child-friendly references to support recall throughout the unit

Supporting scientific vocabulary and understanding in EYFS

Knowledge organisers help children revisit and remember important learning throughout a science topic. This Reception science knowledge organiser supports children as they learn to describe materials, compare objects and talk about simple changes they observe during practical investigations.

It can be used as part of a working wall, during teacher-led discussions, for recap activities or to support children’s independent recording and communication in science.

Linked Reception science unit

This knowledge organiser links directly to our Reception States of Matter science unit and forms part of the wider EYFS Science Scheme. Together, the resources support vocabulary development, scientific enquiry and understanding of materials through practical, age-appropriate investigations.
