Your test dialog: Is water a metal? No water is not a metal. So, it is liquid.
I can think of a lot of other scientific terms that need to be taught in another lesson:
-molecule
-bond
-evaporate
-condense
-boil (غلى؟)
-atom
-nucleus
-proton
-electron
-neutron
-ion
-chemical formula
-base
-acid
-organic
-inorganic
-polymer
-isotope
-half life
-equilibrium
Of course, admittedly this vocabulary can be a bit on the ممل side of things unless you have a good motivation to learn it.
