Meet physicist Andrew Zwicker who is working to raise the status of plasmas in science education. A plasma physicist by training, Andrew is Head of Science Education at Princeton University’s Plasma Physics Laboratory (PPPL) where he spends much of his time introducing high school students, undergraduates and K-12 teachers to the glowing, ionized gases that make up plasmas, and to the important role plasmas play in science.
“Plasmas are hot gases containing a significant number of electrically charged particles, and are common in nature,” says Andrew, “as exemplified by lightning, the solar core and the aurora borealis.” Plasmas also make up such man-made devices as fluorescent light bulbs, fusion reactors, and plasma televisions, he adds. But while 99 percent of the visible universe is in the plasma state, Andrew says, “many schools still teach that there are three states of matter–solid, liquid, and gas– ignoring plasmas entirely.”
Because of the predominance of plasma in the universe, Andrew likes to say, “It’s not the fourth state of matter, it’s the first state.” But textbooks and state and national education standards, for the most part, don’t mention plasmas, so many high school teachers don’t teach them, says Andrew, who is also a lecturer in Princeton’s Writing Program.
To bring home the wonders of plasmas in an unforgettable way to learners , Andrew likes taking undergraduate students and K-12 teachers aboard NASA’s Weightless Wonder aircraft in Houston to conduct mid-air experiments in “dusty plasmas”(relevant to the rings of Saturn or the tail of a comet) and to examine whether hot air rises in microgravity (using a plasma ball or a lava lamp).
