Solids, Liquids, and Gases Explained
Understanding the Three States of Matter Year 3 Science
What is Matter?
Everything around us is made of matter Matter takes up space Matter has weight We can see, touch, and feel matter
Meet the Solids!
Solids keep their shape They don't flow like water Examples: ice, rocks, books, toys Particles are packed tightly together
Solid Detective Activity
Look around the classroom Find 5 solid objects Draw or write them down Share with a partner
Lovely Liquids!
Liquids flow and pour They take the shape of their container Examples: water, milk, juice, honey Particles move around more freely
Solids vs Liquids
{"left":"Solids keep their shape\nLiquids change shape\nSolids don't flow","right":"Liquids flow and pour\nSolids are firm to touch\nLiquids feel wet"}
Gassy Gases!
Gases spread out to fill space We can't always see them Examples: air, steam, balloon gas Particles move very quickly
Balloon Experiment
Blow up a balloon Feel how the gas fills the whole balloon Gently squeeze - the gas moves around Let some air out - what happens?
Think and Share
What happens to water when it gets very cold? What happens to water when it gets very hot? Can matter change from one state to another?
Amazing State Changes!
Ice (solid) melts to become water (liquid) Water (liquid) can freeze to become ice (solid) Hot water makes steam (gas) The same matter, different states!
