Side note: If you’ve been around for a while, then you already know there really wasn’t any begging necessary because this homeschool mama is always up for engaging and hands-on educational activities!

This submarine STEAM definitely packs a lot of punch! You can use this quick and easy under the sea activity to teach your preschoolers and kindergartners about technology, experiment with how submarines work, and even learn about simple physics concepts.

Your kiddos can learn all of that and more with just a few clear bottles, a large bin, and of course some water.

Food coloring is optional, but lots of fun! You know, because who doesn’t love a beautiful blue ocean?

How do you explain a submarine to a child? STEAM activities for kids make explaining how things work easy. After all, little kids learn best through play, and this submarine bottles investigation station is no exception.

Submarines are large vessels that move underwater. The windows of submarines, called portholes, are usually round. Submarines have a tool called a periscope that sticks out above the water.

When a submarine dives, its ballast tanks are filled with water, which makes the submarine heavier. When it’s time to resurface, the water is replaced with air, which makes it lighter and the submarine rises.

Today’s submarine STEAM activity is a wonderful simulation of how submarines work. When we initially put the empty bottles into the water, they both floated on the surface, but as they filled them with water, they sank to the bottom of the bin.

This submarine activity for kids is also a great way to cool off on a hot day! Both the little guy and baby girl had a blast splashing around in the “ocean water” while learning about submarines.
