This is an activity about the states of matter. Learners will participate in a demonstration to reintroduce them to three states of matter: solid, liquid, and gas. The demonstration also introduces them to a fourth state of matter, plasma, through... (View More) investigation of the properties of volume and shape as they relate to common solids, liquids, and gases, and to the mystery matter later identified at the end as plasma. The demonstration also covers plasma's connection to the Sun and connections to science related to the Interstellar Boundary Explorer, or IBEX, spacecraft. This activity complements other IBEX informal education materials. The demonstration requires use of a small plasma ball and, ideally, a slightly darkened room so that the plasma ball can be more easily seen. An instructional video explaining how to facilitate this activity is available: http://bit.ly/125ZW5k. (View Less)
