Some solutions have been mixed up – help the technicians work out which is which

This activity offers a microscale approach to the classic ‘Technician in trouble!’ Some solutions have been mixed up – students must help the technicians work out which is which by planning and carrying out an investigation using only some dropper bottles and a couple of dropping tiles.

Download the student worksheet as well as the teacher and technician notes to try this creative investigation activity with your 14–16 or post-16 classes.
