Submarine Day Unit Study

There are a few different dates noted as “Submarine Day,” one of which is this Saturday, April 17. There seems to be some debate as to whether the date refers to naval submarines or the sandwich of the same name, so why not use both as an inspiration for a fun, unique submarine day unit study. There are a ton of great ways to incorporate a submarine unit study into your homeschool STEM activities. This Homeschool Living features a variety of submarine activities for all ages.

Submarine STEM

This awesome submarine project is a large scale craft project, which is always popular with younger kids! If you have some old cardboard and paper plates, take advantage of a rainy afternoon and build this cool submarine with a view. On March 17, 1898, Irish engineer John Phillip Holland successfully demonstrated his submarine for the first time. His submarines were the first to make use of internal combustion engines on the surface and electric battery power submerged. Challenge your older kids to research and construct replicas of different submarine styles with this homeschool STEM challenge. This is a great opportunity for students to practice their design and critical-thinking skills.

This submarine in a bottle is simple to make, and makes an excellent sensory or calm-down bottle. You can add your own twist on it by adding a variety of ocean-themed accessories. Consider also adding blue and green glitter or sequins, and you can cut out your own simple sea creatures from craft foam.

Experiment with the functions of fins on a submarine by constructing one out of recycled plastic bottles. Note that this science project requires the use of tools and a tub of water, and will require some adult assistance and supervision.

Lunch Sub

Take a break from your submarine day unit study for a submarine-themed lunch featuring one of these interesting–and delicious!–recipe ideas that take you far further than the quintessential lunch meat sandwich.

You might not call this style of sandwich a “sub.” Depending on where you’re from, you may know it as a hoagie, hero, or po’boy. Check out some of the various origin stories for this type of sandwich and it’s different names.
