Try these ideas for chemical "egg race" competitions that engage students and motivate them to follow a scientific or technical career
These resources have been taken from the book In search of solutions. Aimed at those following post-16 chemistry courses, the book encourages students to design their own experiments in relation to the tasks set, and as they overcome the obstacles within the tasks, their inventiveness and enthusiasm flourishes.
