Here are pictures of 'big things', all found in South Australia, with Internet links. 
Your task is to find out what the big thing is called and where it is found.
(I am wondering too if I have missed any.  Do you know of any others?)

I suggest you print this page out so you can keep a record of your findings.

When you have found all the answers, you need to send a list by email to sapp2002@senet.com.au
In your email make sure you give the number of 'the big thing', that you say what it is, and where it is found.

I would prefer that you work in small teams and that you give your team a name.
