EXPERT ANSWER
A model of neutralization reaction between acid and base by showing the change in pH  can be done easily. It can be used as an model for the reaction or to show a chemical change.  pH paper or a pH indicator can be used to show the progress of the reaction.

for phsics : magent is a nice topic- by converting a metal into megnet by elecriticity

for chem. : 1)by showing volcanic erropsion by acid reactions

2) with a little skill in electronics u can create working models of different models of atoms

3)you can always display the neutralisation reaction

naoh +hcl ------> h2o + co2
use concentrate materials
then 
acid and base when mixed gives salt and water
thats the general idea

4)stucture of DNA (double helix)

  •  you may construct an electric bell and show its switch inside a water which concludes that water is a conductor of electricity
  • u may even rotate a turbine by water showing hydle power
