4. Make a folding 'knife' using spent shaving blades. (Safety, elegance). 5. Make a folding easy chair or scale model. (weight, cost) 6. A “post office" balance for weighing letters up to 100g. (cost, ease) 7. Make a device for weighing a cow. (ease of operation, cost) Such examples could be multiplied. Initially, the teachers and students will find the problems very difficult. But this is no cause for despair; it is a part of education. They should start, notwithstanding a high rate of "failures". These are not failures. They are necessary learning stages. Even while they progress, the students could think of new projects. These projects could be taken group wise or individually depending on the ease of getting materials, the cost etc. The time allowed may also be adjusted but should not be too long; a month may be a good interval to start with. If it is too long, the students do not give serious attention until the time limit comes close. We expect that once started, problem-solving exercises will be fun and enjoyed by all.
