The demonstration of refraction using a ripple tank is tricky, and it is a good idea to practise this.
Class practical: The caustic curve and how the aberration can be reduced by reducing the aperture.
Class practical: Showing angle of incidence equal to angle of reflection.
Demonstration: This experiment is well worth the effort of setting it up.
Demonstration: Comparing the paths of a reflected ray of light and a rubber ball.
Class practical: Shows that image and object positions are symmetrical in a plane mirror.
Class practical: identifying that the image in a plane mirror is virtual.
