Teaching the Kid: Separating Mixtures - Free Printable

Let's solve this step by step. The image is about separating mixtures using different physical methods. We are given four pictures (labeled #1 to #4), and we need to identify each method, describe how it works, and then answer questions based on these techniques.

🔹 Step 1: Identify the Separation Methods

Let’s analyze each picture:

#### #1: Funnel with liquid pouring into a flask
- This shows filtration.
- A mixture is poured through a filter paper in a funnel.
- Solid particles are trapped in the filter; liquid passes through.

✔ Name: Filtration
✔ Description: Filtration separates solids from liquids by passing the mixture through a filter. The solid remains on the filter, while the liquid (filtrate) passes through.

---

#### #2: Colander over a bowl
- This is a sieve or screen used to separate larger particles.
- It's used to separate materials by size.

✔ Name: Sieving
✔ Description: Sieving separates components of a mixture based on particle size. Larger particles remain on top of the sieve, while smaller ones pass through.

---

#### #3: Evaporation setup (dish over heat with steam)
- A mixture is heated, causing the liquid to evaporate, leaving behind solids.
- Commonly used for salt water.

✔ Name: Evaporation
✔ Description: Evaporation separates a soluble solid from a liquid by heating the mixture until the liquid turns into vapor, leaving the solid behind.

---

#### #4: Magnet attracting iron filings from a mixture
- A magnet is used to attract magnetic materials like iron.

✔ Name: Magnetic separation
✔ Description: Magnetic separation uses a magnet to attract magnetic materials (like iron) from a mixture, separating them from non-magnetic substances.

✔ Table Answers:

| Picture | Name | Description |
|--------|--------------------|-----------|
| #1 | Filtration | Separates solids from liquids using a filter. The solid stays on the filter, and the liquid passes through. |
| #2 | Sieving | Separates particles by size. Larger particles stay on the screen; smaller ones fall through. |
| #3 | Evaporation | Heats a mixture to turn the liquid into vapor, leaving behind dissolved solids. |
| #4 | Magnetic separation| Uses a magnet to attract magnetic materials (like iron) from a mixture. |

🔹 Now, Answer the Questions Using These Techniques

#### 5. I have a mixture of salt, water, and iron. I pass them through a filter. What is left in the filter and what passes through into the cup?

- Filter (left behind): Iron (because it’s a solid that won’t dissolve)
- Passes through (filtrate): Saltwater (salt dissolves in water, so it goes through)

> ✔ Answer:
> - Left in filter: Iron
> - Passes through: Saltwater

> 📌 *Note:* Salt doesn't get filtered out because it's dissolved.

#### 6. I have a mixture of tomato sauce, sugar, and carrots. I bring a magnet close by. What does the magnet pick up and what is left behind?

- None of these (tomato sauce, sugar, carrots) are magnetic.
- So, the magnet picks up nothing.

> ✔ Answer:
> - Magnet picks up: Nothing
> - Left behind: All three (tomato sauce, sugar, carrots)

---

#### 7. I have a mixture of rocks, sand, and water. I pass it through a screen. What is left on top of the screen and what has fallen through the screen?

- Rocks are large → stay on top
- Sand is small → may go through depending on screen size
- Water → will flow through

Assuming a standard screen:
- On top: Rocks (larger than screen holes)
- Through: Sand and water (smaller particles and liquid)

> ✔ Answer:
> - On top: Rocks
> - Through: Sand and water

---

#### 8. I have a mixture of iron, salt, and water. I heat it up to a boil. Explain what happens to each part of my mixture.

- Water: Turns into vapor (evaporates)
- Salt: Dissolved in water, so it remains in the liquid — as water boils away, salt is left behind
- Iron: Not dissolved; it’s a solid and not affected by boiling. It might sink or float but stays as solid

> ✔ Answer:
> - Water: Evaporates into vapor
> - Salt: Stays dissolved, then crystallizes when water evaporates
> - Iron: Remains as solid particles (does not dissolve or change state)

---

#### 9. I have a mixture of iron, salt, and water. I bring a magnet close by. What does the magnet pick up and what is left behind?

- Magnet attracts iron
- Salt and water are not magnetic

> ✔ Answer:
> - Magnet picks up: Iron
> - Left behind: Salt and water

---

#### 10. I have a mixture of iron, salt, and water. I pass them through a screen. What stays on top and what passes through?

- Iron and salt are fine particles; water is liquid
- If the screen is fine enough:
- Iron and salt may stay on top if they’re solid particles
- But water will pass through
- However, salt dissolves, so it becomes part of the solution

So:
- On top: Iron (solid, not dissolved)
- Through: Saltwater (dissolved salt + water)

> ✔ Answer:
> - Stays on top: Iron
> - Passes through: Saltwater

---

✔ Final Summary Table

| Question | Answer |
|--------|--------|
| 5 | Filter: Iron; Cup: Saltwater |
| 6 | Magnet: Nothing; Left: All components |
| 7 | Top: Rocks; Through: Sand and water |
| 8 | Water: Evaporates; Salt: Leaves behind; Iron: Remains solid |
| 9 | Magnet: Iron; Left: Salt and water |
| 10 | Top: Iron; Through: Saltwater |
