# 5th Grade Science : Model that matter is too small to see

## Example Questions

### Example Question #1 : Model That Matter Is Too Small To See

Which of these is the best models that matter is made of tiny particles?

Possible Answers:

Correct answer:

Explanation:

Matter is anything that takes up space. Matter is in the form of solid, liquid, or gas. Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don’t move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid. The particles of a liquid are close together, always moving, and can slide past one another. In a gas, the particles have very little attraction to each other. They are very far apart compared to the particles in a solid or liquid, and are constantly moving. The particles don’t interact with one another but just hit and bounce off of each other when they collide.

### Example Question #2 : Model That Matter Is Too Small To See

Which of these images best represents the type of matter that has particles that are vibrating in place but not moving past each other?

Possible Answers:

none of these

### Example Question #3 : Model That Matter Is Too Small To See

This image shows the particles in a type of matter. Which type of matter is this image probably showing?

Possible Answers:

gas

none of these

liquid

solid

Correct answer:

liquid

Explanation:

The answer is a liquid. They are too close together to be a gas, but not in a specific formation like a solid.

### Example Question #1 : Model That Matter Is Too Small To See

What answer choice(s) is the benefit of using a scientific model?

Possible Answers:

Models can be used as a tool to support thinking.

All of the answer choices are correct.

Models can be used to generate new questions.

None of the answer choices are correct.

Models are tools that scientists can use to predict events.

Correct answer:

All of the answer choices are correct.

Explanation:

A scientific model can be used a show scientists' understanding of an object, event, or process. Models can be used to generate new questions, used as a tool to support thinking, and models are tools that scientists can use to predict events.

### Example Question #7 : Model That Matter Is Too Small To See

Solids, liquids, and gases are made of tiny particles called ________ and ________.

Possible Answers:

flexibility; neurons

molecules; atoms

electrons; vibrations

protons; molecules

Correct answer:

molecules; atoms

Explanation:

Solids, liquids, and gases are made of tiny particles called atoms and molecules. Atoms and molecules are what make up all matter. They are the smallest particles of any element. They still have the same properties as the element they make up. An atom of aluminum still has the same melting point as an aluminum can. They are so tiny we cannot see their color, but if we zoomed in with a scanning tunneling microscope or electron microscope, we would see they would be the same color.

### Example Question #8 : Model That Matter Is Too Small To See

### Example Question #10 : Model That Matter Is Too Small To See

What is the name of the scientific theory that recognizes that all matter is made of up parts that are too small to be seen without magnification?

Possible Answers:

Law of Thermodynamics

Quantum Theory

Newton's 3rd Law of Motion

Atomic Theory

Correct answer:

Atomic Theory

Explanation:

Atomic theory is the name of the theory described in the question. Atoms are very tiny and cannot be seen without a microscope. They are made up of parts that determine what the atom is, how it acts, and its mass. Inside of atoms are protons, neutrons, and electrons.
