Dissolving & Solutions

ScienceMatter & MaterialsAges 9–10

Teaching Table

Set out your lesson

Practise the bounded task in Dissolving & Solutions; see exact limits before inferring broader coverage.

Activity

Can distinguish dissolved from suspended; never taste experimental liquids or heat them.

Policy

Exact directed source edges retained; earlier authorship is not learner attainment.

Materials

These supplied stage cards
Scrap paper and pencil; oral/pointing response where appropriate

Sequence

Read readiness and decide on support without treating prerequisite authoring as learner readiness.
Open Show first and explain its model.
Use Guided Try with support and its separate adult key.
Close Show and guided keys before Try, unless this Try is explicitly supported.
Reflect on an actual attempt, including help used.

No Printer

Use the supplied screen cards; copying the exact task to paper is optional, not required.

Privacy

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.

Teaching limits and safe use

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

Description reasoning and a plan only; no actual dissolution or recovery observed. Historical solution-versus-mixture contrast is explicitly corrected.

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Check understanding

Explain that dissolving means a solid mixes completely into a liquid to form a solution
Describe how to recover a dissolved substance by evaporating the liquid
Distinguish between a mixture (can see separate parts) and a solution (looks clear, fully dissolved)

“Can your child explain what happens when sugar dissolves in tea, and figure out how to get the salt back from salty water?”
