Here's what I would do.
Why not let the kids search magazines for solids, liquids, and gases (hard to find, but perhaps containers of gases like a hot air balloon or a picture of the sky). Also I'd have the kids do a phase-change dance. You call out "solid" and they stand really close and wiggle just a little, keeping their feet on the floor. When you say, "liquid" they move a little more, spread out, and can walk about. When you say, "gas" they spread out more and really move about. Yell out these phases in any order for a while and you can take a digital picture of them acting out each phase. Then, put pictures of them in these three phases on your bulletin board.
I'd skip all the non-newtonian solids and liquids. I'd also avoid weird things like foams, aerosols, and gels. Too complicated right now. Just stick with the typical liquids, solids, and gases.
