Question 1: Describe the difference between a solid form and a hollow form in 3D design.

Answer: A solid form is a fully filled shape with volume, like a cube or sphere, whereas a hollow form has empty space inside, like a box with open sides or a hollow sphere.

Question 2: List three different materials commonly used in 3D art and sculpture.

Answer: Clay, wood, metal.

Question 3: Explain why understanding light and shadow is important when creating 3D artwork.

Answer: Light and shadow help create the illusion of depth and volume, making the object appear more realistic and three-dimensional.

Question 4: Sketch a simple 3D geometric shape, such as a cube or cylinder, in the space provided. Label the front, side, and top faces.

Answer: A correct sketch should show a basic 3D shape with visible edges and angles. The labels should identify the different faces clearly.

Question 5: Draw a small sculpture of a fruit (like an apple or banana) showing how light falls on its surface. Include highlights and shadows.

Answer: A correct drawing would depict a rounded fruit with areas of highlight where light hits directly and darker shadows on the opposite side, showing volume.

Question 6: Describe two different methods artists use to add texture to their 3D models or sculptures.

Answer: Artists can carve or etch patterns into the surface, or apply different materials or finishes (like rough or smooth textures) to create tactile variety.

Question 7: Sketch a conceptual design for a practical 3D object, such as a pencil holder or keychain, in the space provided.

Answer: A suitable sketch would show the overall shape, with details indicating function, such as openings for a pencil or hooks for keys.

Question 8: Explain what is meant by 'balance' in a 3D sculpture and why it is important.

Answer: Balance refers to the distribution of weight and visual elements so the sculpture remains stable and looks visually steady. It is important for safety and aesthetics.

Question 9: Describe how you would make a lightweight 3D model using recycled materials.

Answer: Use lightweight materials like cardboard, plastic bottles, or foam, and assemble them securely with glue or tape, ensuring the structure is stable and balanced.

Question 10: Design and sketch a futuristic 3D vehicle or gadget, focusing on its form and volume.

Answer: A successful sketch would show a three-dimensional form with clear perspective, showing curves, angles, and volume, indicating it is a functional object.
