For K-12 teachers, engaging students in science, technology, engineering, and math (STEM) topics can spark curiosity and promote a lifelong love of learning. One innovative way to do this is by teaching them about submarines! In this blog post, we provide ideas for incorporating submarine-based lessons into your K-12 curriculum.

Begin with the basics by discussing the history of submarines, showcasing their evolution from simple submersible vessels to the advanced technologies we have today. Show your students images and videos of early submarines and explain how they functioned. Provide context by linking their development to historical events like the Civil War, World War I & II, and the Cold War.

Next, introduce students to the science behind submarine engineering. Explain how buoyancy works and demonstrate with hands-on activities like creating a Cartesian diver – a small plastic bottle filled with water that sinks or floats when pressure is applied to it. Discuss the importance of ballast tanks in ensuring that submarines can maintain buoyancy at varying depths.

Once students have a basic understanding of buoyancy, it’s time to delve deeper into submarine propulsion systems. Teach them about diesel-electric engines found in conventional submarines and how nuclear reactors power modern submarines’ propulsion systems. Explain how propellers have evolved over time from simple designs to sophisticated contrarotating varieties for improved efficiency.

To support comprehension of complex concepts, incorporate multimedia content such as films or documentaries about submarines and include fascinating real-life stories of famous submariners throughout history. Assign reading exercises on underwater exploration or biographies dedicated to pioneering pioneers like Jules Verne’s fictional Captain Nemo or real-life US Navy Admiral Hyman G. Rickover.

Encourage hands-on learning through group projects that prompt creativity and teamwork. For younger students, organize submarine-themed arts and crafts sessions where they can construct their own models using everyday materials such as plastic bottles, cardboard, and duct tape. For older students, consider assigning challenging engineering projects like designing and building an underwater remotely operated vehicle (ROV) to provide real-world applications of their knowledge.

Incorporate field trips or virtual tours to nearby submarine museums, navy bases, or research institutions if it is feasible. This can create an even more immersive educational experience, allowing students to observe actual submarines and interact with professionals in the field.

By teaching students about submarines, K-12 educators can enhance their science curriculum by making abstract STEM concepts approachable and engaging. Submarine-themed lessons open the door to a deeper understanding of not only science and technology but also history, geography, and decision-making skills. Dive into this fascinating topic and witness your students’ enthusiasm for learning grow exponentially!
