Ocean Sensory Bottles

I thought we could use some themed sensory as part of our unit.  I thought it funny looking back at this photo that the bottles were sitting next to the hard hat, as they have been tossed around a bit.  The students in our room like the sounds certain toys make when they hit the tile floor.  Small plastic screws, wooden alphabet blocks, and a few other items must really sound interesting to them as they are dropped on the floor because the students will drop them and then stand still for a moment as if they heard something fascinating....
