Classify mixtures as homogeneous or heterogeneous worksheet | Live ... - Free Printable

Problem Overview:

The task is to determine whether the given mixtures are heterogeneous or homogeneous. Here are the key definitions to guide our analysis:

- Homogeneous Mixture: A mixture that has a uniform composition throughout. The components are blended together, and it appears consistent in appearance.
- Heterogeneous Mixture: A mixture that has different compositions in different parts. The components are not uniformly distributed, and it can be visibly separated into distinct parts.

Step-by-Step Analysis:

#### 1. Lentils
- Substances: Lentils (seeds) with visible vegetables like carrots, onions, etc.
- Mixture: A bowl containing lentils and other vegetables.
- Analysis: The lentils and vegetables are visibly distinct and can be easily separated. Each component retains its original properties (e.g., lentils remain lentils, carrots remain carrots).
- Conclusion: This is a heterogeneous mixture.

#### 2. Smoothie
- Substances: Fruits (e.g., strawberries, bananas, spinach) and possibly other ingredients like yogurt or milk.
- Mixture: A blended drink where all ingredients are mixed together.
- Analysis: In a smoothie, the fruits and other ingredients are blended until they form a uniform consistency. You cannot see individual pieces of fruit or distinguish between the components.
- Conclusion: This is a homogeneous mixture.

#### 3. Fruit Salad
- Substances: Various fruits (e.g., strawberries, blueberries, grapes, etc.).
- Mixture: A bowl containing mixed fruits.
- Analysis: The fruits in a fruit salad are clearly visible and can be easily separated. Each type of fruit retains its original shape and properties.
- Conclusion: This is a heterogeneous mixture.

#### 4. Cake
- Substances: Ingredients like flour, sugar, eggs, butter, and other baking components.
- Mixture: A baked cake with a uniform texture.
- Analysis: After baking, the cake has a uniform appearance and texture. The individual ingredients (flour, sugar, eggs, etc.) are no longer visible or separable.
- Conclusion: This is a homogeneous mixture.

Final Answers:

- Lentils: Heterogeneous
- Smoothie: Homogeneous
- Fruit Salad: Heterogeneous
- Cake: Homogeneous

Completed Table:

| Substances | Mixture | Answer |
|---------------------------------------------------------------------------|-----------------------------------|----------------|
|  |  | Heterogeneous |
|  |  | Homogeneous |
|  |  | Heterogeneous |
|  |  | Homogeneous |

Final Answer:

\boxed{
\begin{array}{ccc}
\text{Lentils} & \text{Heterogeneous} \\
\text{Smoothie} & \text{Homogeneous} \\
\text{Fruit Salad} & \text{Heterogeneous} \\
\text{Cake} & \text{Homogeneous} \\
\end{array}
