Mini Aquarium in a Bottle (Ocean Sensory Play)

These ocean sensory bottles — or, as I like to call them, “mini aquariums” — are ridiculously easy and are a great sensory activity for little hands.
There’s nothing wrong with making these bottles just for something fun and pretty to shake around, but they’re also a great way to learn about sea creatures and ocean life.
Just add a few books ….
Mister Seahorse by Eric CarleIn the Sea by David Elliott
National Geographic Little Kids First Big Book of the Ocean
… and some videos …
Video – Ocean Animals for Kids
Ocean Animals for Preschool & Kindergarten
… throw in some ocean-themed snacks, and you’ve got a super-easy, hands-on unit study!
We used a Voss water bottle for this, but you can certainly be creative with the type and size of bottle that you use.
You can also add a nice touch to your bottle by adding a few small seashells.
