Mixtures and Solutions 5th Grade

What is a mixture?

• A mixture is a combination of two or more substances that can be easily separated.

• A mixture is a single substance that cannot be separated.

• A mixture is a chemical reaction between two or more elements.

• A mixture is a solution that has uniform composition throughout.

What is an example of a homogeneous mixture?

• Saltwater

• Sand and salt

• Oil and water

• Fruit salad

What happens when you mix oil and water?

• They form a homogeneous mixture and blend completely.

• They form a heterogeneous mixture because they do not mix well.

• They create a chemical reaction that produces gas.

• They dissolve into each other and create a solution.

Can mixtures be homogeneous or heterogeneous?

• No, mixtures can only be homogeneous.

• Yes, mixtures can be homogeneous (uniform composition) or heterogeneous (different components visible).

• Mixtures can only be heterogeneous.

• Yes, but they are always uniform.

What is an example of a heterogeneous mixture?

• A salad

• Saltwater

• Air

• Concrete

What is the difference between a mixture and a compound?

• A mixture is a combination of substances that can be separated, while a compound is a substance formed when two or more elements are chemically bonded.

• A mixture is a pure substance, while a compound is a combination of different elements.

• A mixture cannot be separated by physical means, while a compound can be.

• A mixture has a fixed composition, while a compound does not.

Is a mixture a way to classify matter?

• Yes, a mixture is a way to classify matter.

• No, a mixture is not a way to classify matter.

• A mixture is a type of element.

• A mixture is a form of energy.

What is a solvent?

• A substance that dissolves a solute to form a solution.

• A solid that cannot dissolve in any liquid.

• A mixture of two or more substances.

• A chemical reaction that produces heat.

What is filtration?

• Filtration is a method used to separate solids from liquids using a filter.

• Filtration is a process of mixing liquids to create a solution.

• Filtration is a technique for heating liquids to evaporate them.

• Filtration is a method of compressing solids into a smaller volume.

What is a solute?

• A substance that is dissolved in a solution.

• A type of solvent used in chemical reactions.

• A mixture of two or more substances.

• A solid that forms from a solution.
