Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the construction technique?Predominantly 'bread and butter' construction, involving laminated and shaped wooden layers
2. What is the hydrodynamic focus?Emphasizes the hull's form to analyze and optimize stability, speed, and seaworthiness
3. Why do people build half hull models instead of full ship models?They are simpler and focus only on the hull, the part that touches the water. This helps engineers study how fast a ship can go, how steady it is, and how much it can carry.
4. How are half hull models made?Builders cut thin wooden planks and glue them together in layers, shaping them to match the hull’s curves. This technique is called "bread and butter" construction.

Naval Architecture: The engineering discipline concerned with the design, construction, and maintenance of ships and other marine structures.
Hydrodynamics: The study of the forces acting on objects moving through fluids, particularly water in the context of ships.
CAD (Computer-Aided Design): The use of computer systems to assist in the creation, modification, analysis, or optimization of a design.
Seaworthiness: The ability of a ship or boat to withstand the stresses and conditions of normal operation at sea.
