In Kingdom Builders: The Case of the Sinking Boat, Chris, John, Mary, and Martha set out for a fun day of racing toy boats at the local pond. However, when John’s boat unexpectedly sinks instead of floating, the Kingdom Builders spring into action to figure out why and how to fix it. Using the Engineering Design Cycle, the team works together to redesign the boat, making it buoyant and seaworthy.
John gathers lighter materials, Martha sketches a new boat design with a wider, more stable base, and Mary keeps the group focused on working with care and responsibility. After testing and refining their design, the Kingdom Builders successfully create a boat that floats perfectly on the water, allowing them to enjoy their day of boat racing.
This story teaches young readers about the principles of buoyancy and stability, while also reinforcing the importance of teamwork, persistence, and faith. The Kingdom Builders show how even a simple setback can be overcome with creativity, careful planning, and a positive attitude, inspiring children to tackle challenges with confidence and trust in their abilities.
