In continuing to learn about unique animal body parts, students learned about how fish have a ‘Swim Bladder’ which allows fish to swim at different depths of the ocean with ease thanks to the gases inside of it.

Students focused their learning about the Sunfish; a large dish like shaped fish that is distinctly missing a tail! They swim with the fins on the top and bottom of them, and have a special swim bladder that helps them navigate the water.

Together, we made a weighted water craft in a bottle to show how the fish move from the top to the bottom of the ocean.

Students had a lot of fun and at the same time made a great accessory for the classroom.
