Question 1: Describe what a three-dimensional shape is and give two examples of common 3D objects you might find in everyday life.

Answer: A three-dimensional shape has length, width, and height, giving it volume. Examples include a cube and a sphere.

Question 2: Explain the difference between solid and hollow 3D forms. Provide an example of each.

Answer: A solid form is completely filled with material, like a brick. A hollow form has an empty space inside, like a pipe.

Question 3: List three different materials that can be used in 3D design projects and mention one characteristic of each.

Answer: Wood (sturdy and natural), clay (malleable and soft), metal (strong and durable).

Question 4: Describe the process of building a simple 3D model using basic materials such as paper, cardboard, or modelling clay.

Answer: Start by sketching your design, then cut or mould the materials into the shapes needed, and assemble them using glue or tape to create the final form.

Question 5: Sketch a simple 3D geometric shape, such as a cube or cylinder. Include shading to suggest depth.

Answer: A correct sketch would show a 3D shape with visible edges, proper perspective lines, and shading on one side to indicate light source and depth.

Question 6: Design and sketch an ergonomic handle for a tool or object. Think about how the shape fits comfortably in the hand.

Answer: A successful sketch would depict a handle with smooth curves, a grip area with textured surface, and appropriate size for holding comfortably.

Question 7: Explain how texture can be added to a 3D model and why it is important in design.

Answer: Texture can be added by carving, adding materials, or painting. It makes the object more realistic and interesting, and can influence how it feels or looks.

Question 8: Identify two different ways to join or assemble parts of a 3D model and describe when you might use each.

Answer: Gluing is used for paper or lightweight materials; screwing or bolting is used for stronger, more durable connections in heavier materials.

Question 9: Describe what a scale model is and how it can be useful in 3D design projects.

Answer: A scale model is a smaller or larger version of an object, used to study or present the design before making the full-size version.

Question 10: Discuss the importance of symmetry in 3D design. Provide an example of a symmetrical object.

Answer: Symmetry creates balance and harmony in design. An example is a human face or a decorative vase.

Question 11: Sketch a concept for a futuristic 3D sculpture that incorporates multiple forms and textures. Label the different parts of your design.

Answer: A successful sketch would show various shapes combined into a cohesive form, with different textures indicated by shading or patterning, and labels pointing to each part explaining their features.
