Freeze! Sign up right now for this workshop if you teach about our favorite molecule, Dihydrogen Monoxide! We have the solution (or precipitate) for a far out morning of learning about solids, liquid and gas.  Topics will range from chemistry in your classroom to Pluto’s icy moon.

Don’t be all wet, go with the flow and join us as we investigate the Mickey Mouse molecule. See you real soon.
