In a gas, the particles have very little attraction to each other.The particles of a liquid are close together, always moving, and can slide past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid.They are close together and vibrate in position but don’t move past one another. In a solid, the particles are very attracted to each other.
Solids, liquids, and gases are made of tiny particles called atoms and molecules.Matter on Earth is in the form of solid, liquid, or gas.Finally, students will use their models of solids, liquids, and gases to explain their observations in the lesson. Students will use the model to describe the differences in attraction among the particles of a solid, liquid, and gas. Students will develop a model to describe that matter is made up of tiny particles, too small to be seen.
