Build, Test & Sail Paper Engineering Kit

Use without printing: Read the explanations and diagrams on screen and keep a digital experiment journal with predictions, observations and comparisons of the two hull designs, sail shapes and folded supports. You can study and plan the experiments without making a model. Physical building still requires the specified materials and correctly measured templates; follow the supplied safety and dry-table instructions.

Build two paper hull designs, compare sail shapes and investigate folded-paper support structures with printable templates, directions, experiment records and explanations. These are modern engineering models, not scale historical ship replicas.

20 pages. Ages 8+ with adult supervision throughout. This is a printable activity kit, not a shipped materials kit. Use only the specified supplies and dry-table activities; keep models out of water. The templates and instructions were digitally checked, but the activities have not been physically prototyped. Treat results as experiments, not guaranteed performance. Read the safety pages before building, print cut sheets single-sided at 100%, and check every template scale.
