Students are introduced to the pain reliever 'Entonox' a gas made from molecules comprised of nitrogen and oxygen.

Students have ten minutes to build a moli-model and read an information sheet related to a compound of nitrogen and oxygen to see if it would be suitable for pain relief.

Once students have completed three models they come to a conclusion of which gas would be most suitable: nitrogen monoxide, dinitrogen monoxide or nitrogen dioxide.

Higher level students can be introduced to coefficients and subscripted numbers in relation to symbol formulae.
