Worksheet demonstrating four methods of separating mixtures: filtration, evaporation, distillation, and magnetic separation.

Problem Overview:

The task involves identifying and describing four methods of separating mixtures, as depicted in the images. After that, you need to apply these separation techniques to solve specific problems involving different mixtures.

Step 1: Identifying and Describing the Separation Techniques

#### Image #1:
- Name: Filtration
- Description: Filtration is a method used to separate solids from liquids by passing the mixture through a filter. The solid particles are retained on the filter, while the liquid passes through.

#### Image #2:
- Name: Evaporation
- Description: Evaporation is a method used to separate a soluble solid from a liquid by heating the mixture. The liquid turns into vapor and escapes, leaving the solid behind.

#### Image #3:
- Name: Distillation
- Description: Distillation is a method used to separate components of a liquid mixture based on their boiling points. The liquid with the lower boiling point evaporates first and is condensed back into a liquid.

#### Image #4:
- Name: Magnetization (Magnetic Separation)
- Description: Magnetic separation is used to separate magnetic materials (like iron) from non-magnetic materials by using a magnet to attract the magnetic component.

Step 2: Applying the Separation Techniques to Solve the Problems

#### Question 5:
Problem: 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?

- Solution:
- Filter: Iron (solid, cannot pass through the filter).
- Cup: Salt solution (salt dissolved in water can pass through the filter).

#### Question 6:
Problem: 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?

- Solution:
- Magnet picks up: Nothing (tomato sauce, sugar, and carrots are not magnetic).
- Left behind: Tomato sauce, sugar, and carrots.

#### Question 7:
Problem: 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?

- Solution:
- On top of the screen: Rocks (larger particles cannot pass through the screen).
- Falls through the screen: Sand and water (smaller particles and liquid pass through).

#### Question 8:
Problem: 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.

- Solution:
- Iron: Remains as a solid at the bottom of the container (iron does not evaporate).
- Salt: Remains as a solid at the bottom of the container (salt does not evaporate but stays dissolved until all the water is gone).
- Water: Evaporates into the air as steam.

#### Question 9:
Problem: 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?

- Solution:
- Magnet picks up: Iron (magnetic material).
- Left behind: Salt and water (non-magnetic materials).

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

- Solution:
- On top of the screen: Iron and salt (both are solids and will not pass through the screen).
- Passes through: Water (liquid can pass through the screen).

Final Answers:

1. Filtration: Separates solids from liquids.
2. Evaporation: Separates a soluble solid from a liquid by heating.
3. Distillation: Separates components of a liquid mixture based on boiling points.
4. Magnetic Separation: Separates magnetic materials from non-magnetic materials using a magnet.

#### Specific Problem Solutions:
5. Filter: Iron; Cup: Salt solution.
6. Magnet picks up: Nothing; Left behind: Tomato sauce, sugar, and carrots.
7. On top of the screen: Rocks; Falls through: Sand and water.
8. Iron: Remains as a solid; Salt: Remains as a solid; Water: Evaporates.
9. Magnet picks up: Iron; Left behind: Salt and water.
10. On top of the screen: Iron and salt; Passes through: Water.
