Match the method to the property that makes the parts different
Part 1 · Interactive Model
Pick a Mixture & a Method
Choose a mixture, choose a method, and run it. A method only works if the parts differ in the property it targets — size, magnetism, solubility, or boiling point.
Part 2 · Predict Before Reveal
Choose the Right Method
Read the mixture. Pick the method that separates it before the reveal, then lock it in.

Part 3 · Step-by-Step Machines
Three Reasoning Machines
Pick a mixture. The matcher reasons from the parts' properties to the method that works.
Pick a physical property. The detective shows which separation method that property unlocks.
A tricky mixture of salt + sand + iron filings needs several steps in the right order.

Word Box
Mixture
Two or more substances physically combined, not chemically bonded, so they keep their own properties.
Filtration
Separates an insoluble solid from a liquid using filter paper; the solid stays, the liquid passes through.
Evaporation
Heats a solution so the liquid escapes as vapor, leaving the dissolved solid behind.
Distillation
Boils then cools a mixture of liquids to collect them separately by boiling point; recovers the liquid.
Magnetism
A magnet pulls out a magnetic solid (like iron) from a non-magnetic one.
Sieving
Separates solid pieces by size; large pieces stay on the mesh, small ones fall through.
Soluble
Able to dissolve in a liquid; a dissolved solid passes through filter paper.
Physical property
A trait like size, solubility, magnetism, or boiling point used to separate parts without changing them chemically.
