Which of these students is doing a demonstration that proves matter is made of tiny particles we cannot see?
- Monica blows air into a balloon and it gets bigger and bigger. She can't see anything inside the balloon, but she can feel that there is air in it!
- Deontay is ripping apart a piece of paper. He keeps ripping it into smaller pieces until he can't anymore. He thinks if he had a machine to keep ripping it, he could make it smaller.
- Celeste is using a light to grow plants in a dark closet indoors. The plants are growing even though they aren't in the sun!
Monica
Monica and Deontay
Celeste
Celeste and Deontay
Deontay
Explanation
The answer is Monica because she is moving more matter (tiny particles) into a balloon and even though we cannot see them, we can see how the balloon gets larger. Deontay is correct that he could keep breaking things apart, but he has a hypothesis and is not conducting an experiment or a demonstration. Celeste's project is about photosynthesis.
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.
What answer choice(s) is the benefit of using a scientific model?
Models can be used to generate new questions.
All of the answer choices are correct.
Models can be used as a tool to support thinking.
Models are tools that scientists can use to predict events.
None 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.

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.
What type of matter is described below?
- In this type of matter, the particles have very little attraction to each other. They are far apart and frozen in place, but can slide past each other if necessary.
solid
liquid
gas
none of these
Explanation
The answer is none of these because the description mixes several key features of solids, liquids, and gases.
