Scientists Model Particles in a Medium
Scientists Model Particles in a Medium is a skill on Pengi from Lesson 1: The Medium (Particle Theory) in Amplify Science (California) Grade 4.
Key Concepts
Because particles are too small to be observed directly, scientists use models to explain their behavior. A particle model visualizes the medium as a collection of unconnected spheres. This helps explain phenomena that are invisible, such as sound waves .
By using this model, scientists can demonstrate that sound is not a continuous stream of air, but rather a sequence of vibrations passing between individual, interacting particles according to particle theory .
