Educational worksheet on separating mixtures, featuring matching exercises and a table to identify the correct separation method for different mixtures.

Let's solve this step by step.

Part 1: Match the process to its correct description

We need to draw a line from each separation process on the left to its correct description on the right.

#### Processes and Descriptions:

1. Evaporating and Condensing
→ *Separates soluble solids from liquids*
✔ Correct: This is used to separate a dissolved solid (like salt) from a liquid (water). The water evaporates, leaving the solid behind; then the vapor can be condensed back into liquid if needed.

2. Decanting
→ *Separates two liquids which have different weights*
✔ Correct: Decanting is used when two immiscible liquids (like oil and water) form layers based on density. You pour off the top layer.

3. Magnetism
→ *Separates iron and steel from non-magnetic materials*
✔ Correct: A magnet attracts magnetic materials like iron and steel, separating them from non-magnetic substances.

4. Filtering
→ *Separates insoluble solids from liquids*
✔ Correct: Filtering uses a filter paper or mesh to trap solid particles while allowing the liquid to pass through.

5. Sieving
→ *Separates different sized solids*
✔ Correct: Sieving separates solids based on particle size—larger particles stay on the sieve, smaller ones pass through.

✔ Matching Summary:

| Process | Correct Description |
|-----------------------|---------------------|
| Evaporating and Condensing | Separates soluble solids from liquids |
| Decanting | Separates two liquids which have different weights |
| Magnetism | Separates iron and steel from non-magnetic materials |
| Filtering | Separates insoluble solids from liquids |
| Sieving | Separates different sized solids |

Part 2: Write in the process used to separate each mixture

Now, apply the above knowledge to choose the correct separation method for each mixture.

| Mixture | Process | Explanation |
|----------------------|------------------------|-----------|
| salt + water | Evaporating and Condensing | Salt is soluble in water. Heating evaporates water, leaving salt behind. |
| sugar + water | Evaporating and Condensing | Sugar dissolves in water. Same as above—evaporation recovers sugar. |
| rice + pasta shapes | Sieving | Both are solids but of different sizes. Sieving separates them by size. |
| sand + water | Filtering | Sand is insoluble in water. Filtering removes sand from water. |
| flour + rice | Sieving | Flour is fine powder, rice is larger grains. Sieving separates them. |
| paperclips + sawdust | Magnetism | Paperclips are made of steel/iron and are magnetic; sawdust is not. A magnet pulls out the clips. |
| oil + water | Decanting | Oil and water don’t mix and form layers due to different densities. Pour off the top layer (oil). |

✔ Final Answers Table:

| Mixture | Process |
|----------------------|----------------------------|
| salt + water | Evaporating and Condensing |
| sugar + water | Evaporating and Condensing |
| rice + pasta shapes | Sieving |
| sand + water | Filtering |
| flour + rice | Sieving |
| paperclips + sawdust | Magnetism |
| oil + water | Decanting |

✔ Summary of Key Concepts:

- Soluble solids (salt, sugar) → Evaporating and Condensing
- Insoluble solids in liquid (sand in water) → Filtering
- Different-sized solids (rice vs. pasta, flour vs. rice) → Sieving
- Magnetic vs. non-magnetic solids (paperclips vs. sawdust) → Magnetism
- Immiscible liquids with different densities (oil & water) → Decanting
