One of our favourite places we visited on our recent holiday was the Inverloch Shell Museum. It is a community museum with over 6000 shells in display. Little B loves everything to do with the ocean and has quite the shell collection himself, so this was a must do for us, but I think most people would find it interesting as well.
The museum cost $5 entry for a family and is made up of collection of shells, crabs and even preserved octopuses. The sheer variety of shells was mind boggling as was the size of some of them. In different corners they have touch tables, where you can touch different shells as well as things like starfishes, and fish bladders.
It is set within the Bunurong Environment Centre, which also had other really interesting free displays. Firstly a dinosaur display provided by Monash University, which allows children to dig for fossils, do dinosaur puzzles and watch the history of dinosaur discoveries in the South Gippsland area.
Secondly more hands on displays about the forests and the seas. Little B loved a faux forest floor where you could search for different objects with tweezers and a magnifying glass.
This area allowed children to put shells into alphabetical order, or draw pictures to add to a collage of the foreshore. It was also really interesting for Granny B and I as it talked about all the environmental conservation measures the local community had taken to eradicate the marine pest, the Northern Pacific Seastar (they removed them all by hand over a 2 year period).
Little B absolutely loved the hands on nature of these displays, especially being able to touch shells and starfishes. He hopes to go there again "really soon" :-)
