Why not use a controversial, intriguing or mysterious object to kick start a discussion?
For a lighthearted discussion, the Talk Science team recommends:

- Gas energy saving gadget - energy saver or waste of time?
- Eco Wash Balls - an envriomentally-friendly alternative to washing with detergents.
For a serious and challenging discussion, try showing your students these controversial objects from the museum's collections:
