|---|
| Materials | Salt, sugar, sand, water, cups |
|---|
| Key vocabulary | dissolve, soluble, insoluble, solution, solvent |
|---|
| Engage (starter) | "Where does sugar go in your drink?" |
|---|
| Develop (main) | Interactive: test which solids dissolve; sort soluble and insoluble; introduce solution and solvent; tap-to-reveal dissolving. |
|---|
| Plenary (close) | Name a soluble solid. |
|---|
| Assessment | Classifies by solubility. |
|---|
| Teacher notes | Water is the solvent here. |
|---|
Day 3: Factors Affecting Dissolving

| Objectives | Investigate what makes solids dissolve faster. |
|---|
| Materials | Sugar, warm/cool water, timer, spoon |
|---|
| Key vocabulary | fair test, temperature, stirring, rate |
|---|
| Engage (starter) | "How can we speed up dissolving?" |
|---|
| Develop (main) | Interactive: plan a fair test changing one factor (heat, stirring, or grain size); time and record; tap-to-reveal fair testing. |
|---|
| Plenary (close) | What made the sugar dissolve faster? |
|---|
| Assessment | Plans a fair test. |

|---|
| Key vocabulary | separate, sieve, filter, magnet, evaporate |
|---|
| Engage (starter) | "How would you separate salt from sand?" |
|---|
| Develop (main) | Interactive: separate mixtures by sieving, filtering, magnetism, and evaporation; match method to mixture; tap-to-reveal methods. |
|---|
| Plenary (close) | How can we separate salt from salt water? |
|---|
| Assessment | Separates mixtures. |
|---|
| Teacher notes | Method depends on the properties. |
