Tyler watched the students filing in, arms crossed before him and a covered Styrofoam chest with a slight curl of steam rising from it resting on the lab table at the front of the class. When it seemed like everyone who was going to come was there, he started to talk.
"Morning. I am hoping all of you got through the weekend okay. I had visits with some of your friends and relatives; I promise everything I said was true, and most of it was good."
He drew a deep breath, lifting the loose-fitting lid off the chest and watching the steam rise. "All right. Now. Fun part. Dry ice. This is frozen carbon dioxide -- the same stuff that makes soda fizzy. Cool thing about dry ice, it doesn't really want to freeze on this planet, so if you force it to, it's continuously evaporating and turning into a gas." With gloved hands, he reached into the chest and brought out a kernel of the ice, then dropped it into a black plastic film can. A few seconds later, the lid of the canister flew off, narrowly missing the first row of chairs. Tyler smirked, then continued his lecture about the properties and uses of dry ice and the science behind it.
"For your lab segment today, I'm just going to let you play with this stuff." He started handing out one-pound chunks in small trays, placing them in front of each student alongside some other supplies they might want to use to test the ice. A light fog from the ice's evaporation filled the room. "Wear lab gloves unless a cold burn sounds like fun to you. Here is a handout with some ideas to get you started. I like the comet myself."
Once everyone had some ice, he waited at the back of the classroom. "Go to it. I'm around."
