Ideas for Teachers on the Theme "Under the Sea"

Updated April 17, 2017

There are several content areas that can be covered when designing an "Under the Sea" theme for a classroom. The animals and plant life under the ocean's surface offer a wide variety of ideas for classroom decorations, lesson plans and projects for students. The "Under the Sea" theme can stimulate students' imagination and create a thirst for learning about life under the sea.

"Under The Sea" Classroom Decorations

If you are going to teach an "Under the Sea" unit, your classroom should reflect the theme. Decorate the room with images of fish, sea shells, sunken ships and other items you would find under the surface of the sea. Many of these items can be found at teacher supply stores, but most can be made by your students. Have your students colour and cut out pictures of starfish, seashells, fish and other creatures. Have students decorate the walls with their artwork.

"Under The Sea" Lesson Plans

You can create useful and enjoyable lesson plans for your "Under the Sea" unit. All four core subjects can blend into the theme to keep the classroom interested. Grade level reading units about the ocean can be obtained from the Internet or from the school library. Writing prompts can then be assigned from the reading, allowing students to expand and demonstrate the knowledge they have learnt from the reading. Math sheets can be made sea-related by putting nautical-theme clip art on the top. Science and social studies can be blended in a mixed lesson plan where the plant and animal life of the sea can be combined with a social studies unit on sea travel.

School-Based "Under The Sea" Student Projects

Individual and group projects for students geared toward the "Under the Sea" theme can be easily made. One such project could be to put together an aquarium for the classroom. Students can decide what kind of rocks should be at the bottom, what kind of coral or decorations should be used, whether the tank should be fresh or salt water, and what kind of fish will go into it. This could branch into a discussion about competition, environment, life cycle and nutrients that the aquarium needs to be a healthy environment for fish.

"Under the Sea" Home Projects

Projects your students can do at home as part of the "Under the Sea" unit can relate to water salinity, density and undersea life. Have students bring shells or other ocean artefacts from home for show and tell. The students can do experiments at home with salt water and fresh water to find which is more dense and determine salinity levels. Assign students to watch undersea programs on Animal Planet or National Geographic channels and write a response on what they have learnt.
