Separating Mixtures

Use knowledge of solids, liquids, and gases to decide how mixtures might be separated through filtering, sieving, and evaporating

Lesson

Set out your lesson

Choose a separation method from material properties and distinguish recovering salt from recovering water.

Before teaching

Use this short check, then start teaching.

Activity

Inferred, not a taxonomy edge: learner can access the supplied prompt with agreed support and can explain or mark a response. If earlier skills are unfamiliar, use the prerequisite topic for teaching; an authored prerequisite is not proof this learner is ready.

Printer, credit, and teaching notes

Sequence

Keep the two adult-only cards off the learner screen. Have a pencil and scrap paper if useful; oral pointing/typing/AAC can replace handwriting unless spelling or composition is the target. No printing, cutting, account or purchase is required.
Open Show first, read the explanation together, and pause to check the central idea. Then do Guided Try together.
For Try, close earlier models and the adult keys unless the task explicitly supplies a reference. Record any hints, read-aloud help or model reopening; do not call supported work independent.
Use only the active learner card. Keep the private key closed until an attempt is recorded. Stop or take a break on request; practical claims stay not observed unless actually done.

No Printer

Use on screen; read aloud or recreate a tactile model only with declared support. No printer or purchased kit.

Privacy

Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view.

Teaching limits and safe use

These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.

Planning only, no practical separation observation. Evaporation alone does not recover all three substances: uncollected vapour is not recovered water.
These bounded examples do not establish independent performance in other situations. Record the support used.

Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.

Check understanding

Choose the correct separation method for a given mixture (sieving for large particles, filtering for small, evaporating for dissolved)
Describe a multi-step separation plan for a complex mixture like sand, salt, and water
Explain why each method works based on the properties of the materials

“If your child has a mixture of sand, salt, and water, can they figure out a step-by-step plan to separate all three using a sieve, filter, and evaporation?”
