There are three basic states of matter: Solid, liquid, and gas. Help your learners with visual impairments to understand the chemical nature of each state of matter with tactile elements. Marbles are used to model the particles in each state of matter, and then trash bags are filled with a solid, a liquid, and air to represent each state. This is a great idea, but you could also have them feel a rock, water, and air blowing as well.
