I have a question in regard to a lesson I plan on doing. I wanted to give students different samples of matter in regard to the three states. What could I use for 3rd graders to know a gas? I mean of course the air in the room is something that can be used, but what are some other ideas? Also, what are some other activities that I can do to help students classify and describe the three states of matter?

Here's an idea for another example: the neon gas in a tube, the helium gas in a balloon, the anesthesia patients get in a hospital. If you look up "triple point", there's videos of substances at the exact temp & pressure where all 3 phases can exist. Other than acting out the molecules, I don't have any activities.

Here is a short video from FunScienceDemos which you may show or reproduce the lesson. FunScienceDemos is a youtube channel which teaches young learners important science concepts that they should know before entering highschool. These concepts are tied to the Next Generation Science Standards. For ELL learners, it is translateable into any language.
