Matter is made of tiny particles called atoms. Everything around us—air, water, food, toys—is made of these building blocks.
Substances can be mixed without changing. Some materials can be combined, but each keeps its own properties.
Chemist – Mix chemicals to create medicines, cleaning products, or new materials.
Food Scientist/Chef – Combine ingredients and understand how they react when cooked or mixed.
Pharmacist – Know how different medicines interact safely.
Materials Engineer – Design new materials, like stronger plastics, fabrics, or building materials.
Environmental Scientist – Study water, air, and soil to understand pollution and clean up the environment.
Cosmetic Scientist – Create lotions, makeup, and shampoos by mixing substances carefully.
Lab Technician – Test substances to see how they behave or combine.
Matter – Anything that takes up space and has weight. (Everything around you!)
Atom – Tiny building blocks that make up all matter.
Solution – A mixture where one substance spreads evenly in another (like sugar in water).
Mixture – Two or more substances together that keep their own properties (like sand and water).
Matter can change between solid, liquid, and gas:
Melting – solid → liquid (ice → water)
Freezing – liquid → solid (water → ice)
Evaporation – liquid → gas (puddle → water vapor)
Condensation – gas → liquid (steam → water drops)
Sublimation – solid → gas (dry ice → gas)
💡 Tip: Matter changes its form, but it’s still made of the same tiny atoms!
Mixture – Two or more substances mixed together, but each keeps its own properties.
Example: Sand and water mixed together—you can still see and separate the sand.
Solution – A special kind of mixture where one substance spreads completely into another and you can’t see it anymore.
Example: Sugar dissolved in water—the sugar disappears but is still there.
💡 Think about it:
Mixtures are like a fruit salad—you can see all the pieces.
Solutions are like lemonade—everything blends together and looks the same.
Mixture (can easily be separated)
Solution (together forever!)
