Explanation:
The muscular system allows for movement within the body, for example, during digestion or urination. Smooth muscles in the gastrointestinal or GI tract control digestion. The GI tract stretches from the mouth to the anus. Food moves through the digestive system with a wave-like motion called peristalsis.
Particles in a solid are tightly and closely packed together. They do not move. For example rock, wood etc.
Particles in a liquid are loosely packed as compared to solids.They move or slide slowly. For example water.
Particles in gases are very loosely packed and freely move and float. For example oxygen.
The students will have to model their marbles accordingly. For solids they will have to put the marbles together in a cluster. For showing liquids, they will have to arrange marbles with slight gaps between them. For showing gases, they will have to arrange the marbles sparsely and scatter them in the box.
