A mixture in which substances break up into their most basic particles, which are too small to be seen, and spread evenly through another substance.

5th Grade Science: Exploring Mixtures, Solutions, and Properties of Materials

1. What is a mixture?

A mixture of substances where the atoms are chemically bonded together.

A substance that cannot be separated into simpler substances by chemical means.

A single substance formed by the chemical combination of two or more elements.

Two or more substances that can be mixed together, but can be separated out, because their atoms are not combines.

A mixture consists of two or more substances that are physically combined, not chemically bonded, allowing them to be separated out.

Explanation

A mixture consists of two or more substances that are physically combined, not chemically bonded, allowing them to be separated out.

2. What is a solution?

A solid substance formed by the solidification of a liquid.

A thick liquid substance used for cooking or lubricating machinery.

A gas with a scent that is spread through the air.

A solution specifically refers to a mixture where substances break down into smaller particles and are evenly distributed within another substance. It is different from the other options provided.

Explanation

A solution specifically refers to a mixture where substances break down into smaller particles and are evenly distributed within another substance. It is different from the other options provided.

3. What does hardness refer to?

How heavy an object is

What color an object is

How tall an object is

Hardness refers to the ability of a material to resist scratching, abrasion, or indentation. It is not related to weight, color, or height of an object.

Explanation

Hardness refers to the ability of a material to resist scratching, abrasion, or indentation. It is not related to weight, color, or height of an object.

4. What does the term 'Texture' refer to?

What color is it?

How big is it?

How heavy is it?

Texture refers to the surface quality or feel of an object, not its color, weight, or size.

Explanation

Texture refers to the surface quality or feel of an object, not its color, weight, or size.

5. What is magnetism related to?

Is it conductive? Will it allow electricity to flow through it?

Is it magnetic? Will a magnet attract it?

Is it transparent? Will light pass through it?

Is it heat-resistant? Will it withstand high temperatures?

The correct answer assesses if an object exhibits magnetic properties and if it will be attracted to a magnet. The other incorrect answers do not pertain to magnetism.

Explanation

The correct answer assesses if an object exhibits magnetic properties and if it will be attracted to a magnet. The other incorrect answers do not pertain to magnetism.

6. What does odor refer to?

What does it sound like?

How does it look?

What does it taste like?

Odor specifically relates to the sense of smell, and it is perceived through the nose. It is different from how something looks, sounds, or tastes.

Explanation

Odor specifically relates to the sense of smell, and it is perceived through the nose. It is different from how something looks, sounds, or tastes.

7. What does the term melting point refer to?

The point where a substance releases gas

At what temperature will it melt or freeze? For example, water melts or freezes at zero celsius.

The point where a substance changes color

The point where a substance becomes solid

The melting point of a substance refers to the temperature at which it changes from a solid to a liquid state or vice versa. It is specific to each substance and can be used to identify and characterize different materials.

Explanation

The melting point of a substance refers to the temperature at which it changes from a solid to a liquid state or vice versa. It is specific to each substance and can be used to identify and characterize different materials.

8. What is elasticity?

A fabric's ability to remain in its original shape after being stretched.

How much will it stretch or bend without breaking? Will it bounce?

The measure of a material's weight compared to its volume.

The ability for a material to change color when exposed to light.

Elasticity refers to a material's ability to stretch or bend without breaking and also its ability to return to its original shape after being stretched. It is not related to weight, volume, or color change.

Explanation

Elasticity refers to a material's ability to stretch or bend without breaking and also its ability to return to its original shape after being stretched. It is not related to weight, volume, or color change.
