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.

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.

The answer is none of these because the description mixes several key features of solids, liquids, and gases.

Atoms 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.

We cannot see atoms with the naked eye. Trillions of atoms could fit inside the dot on top of the letter "i." The radius of an atom is less than one nanometer or a billionth of a meter.

Electrons have a negative charge. The proton moves around the nucleus of an atom, which is in the center. The charge of an electron is opposite but equal to the charge of a proton. Atoms have the same number of electrons as protons. We cannot see these with our eyes, and even with a high-powered microscope, they are too tiny and too low in mass to see.
