Help Tinkering table

As part of their inquiry into 'Will all of the world's problems ever be solved?', the Year 3-6 students are going to be tinkering and exploring the features of inventions we use every day. They will be exploring the design processes that inventors use when they come up with new ideas.  

If you have any old hand tools and household items (toasters, DVD players, computers, etc) that the students can tinker with and pull apart to explore we would be really grateful. Please send them into school.
