Book fairs are exciting events that promote literacy and a love for reading among students. They provide an opportunity for students to explore a wide range of books and discover new stories, characters, and worlds. One of the most popular themes for book fairs is the "Under the Sea" theme. This captivating theme takes students on an underwater adventure, immersing them in a world of imagination and wonder. In this article, we will explore the "Under the Sea" book fair theme and discuss how it can be brought to life in a school setting.

Setting the Stage

Creating an Underwater Atmosphere

To create an immersive experience for students, it is essential to set the stage and create an underwater atmosphere. Start by transforming the book fair venue into an underwater world. Decorate the space with blue and green streamers, hang fish and sea creature cutouts from the ceiling, and place inflatable sea creatures around the room. Use blue lighting to mimic the ocean's depths and play soft, ambient sounds of waves and underwater life to complete the atmosphere.

The Entrance

The entrance is the first impression students and visitors will have of the book fair. Make it memorable by creating an impressive entrance that transports them to the underwater world. Hang a sign that says "Welcome to the Under the Sea Book Fair" and decorate it with colorful fish and sea plants. Use blue fabric or a tarp to create a tunnel-like entrance, resembling the entrance to the ocean.

Book Displays

The heart of any book fair is the books themselves. Arrange the books in creative and visually appealing displays that align with the "Under the Sea" theme. Create displays that resemble coral reefs, shipwrecks, or treasure chests. Use blue fabric or tablecloths to mimic waves and incorporate seashells, starfish, and other sea-inspired props to enhance the displays.

Activities and Games

Storytime with Mermaids and Pirates

Organize special storytime sessions where mermaids and pirates read aloud to the students. Encourage them to dress up in mermaid or pirate costumes to add to the excitement. This interactive storytelling experience will captivate the students' imagination and make them feel like they are part of the underwater adventure.

Underwater Treasure Hunt

Create an underwater treasure hunt activity where students search for hidden treasures throughout the book fair. Provide them with treasure maps and clues that lead them to different book displays. The students can collect stamps or stickers at each display, and those who complete the treasure hunt can receive a special prize or certificate.

Sea Creature Crafts

Set up a craft station where students can create their own sea creatures using various art materials. Provide templates and instructions for making paper plate jellyfish, seashell ornaments, and fish puppets. This activity not only engages students creatively but also reinforces the "Under the Sea" theme.

Author Visits and Book Talks

Inviting Oceanographers and Marine Biologists

Arrange for guest speakers, such as oceanographers or marine biologists, to visit the book fair and give talks about the wonders of the ocean. They can share their experiences, knowledge, and stories related to marine life, conservation, and exploration. This will not only educate the students but also inspire them to learn more about the ocean and its inhabitants.

Author Book Signings

Invite authors who have written books with an underwater theme to participate in the book fair. Organize book signing sessions where students can meet the authors, ask questions, and get their books personally signed. This interaction with authors creates a memorable experience and encourages students to further explore their works.

Merchandise and Souvenirs

Under the Sea-themed Bookmarks

Create custom bookmarks featuring popular sea creatures or quotes from underwater-themed books. These bookmarks can be given out as freebies or sold at a minimal cost. They not only serve as practical souvenirs but also promote reading and remind students of their underwater adventure at the book fair.

Underwater-themed Stationery

Design and produce underwater-themed stationery items such as pencils, erasers, notebooks, and stickers. These items can be sold at the book fair, providing students with a tangible reminder of their experience. The stationery can feature popular sea creatures, underwater landscapes, or quotes from beloved books.


The "Under the Sea" book fair theme offers a magical and immersive experience for students, encouraging their love for reading and exploration. By creating an underwater atmosphere, organizing engaging activities and games, inviting guest speakers and authors, and offering themed merchandise, the book fair becomes a memorable event that sparks the students' imagination and curiosity. Through this theme, students dive into a world of stories and discover the treasures hidden in the depths of the ocean.
