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

Answer: A solid form is a completely filled, three-dimensional shape with no hollow spaces inside, like a clay cube. A hollow form has empty space inside, such as a wireframe sculpture or a hollow sphere.

Question 2: List three different materials you could use to create a 3D sculpture and briefly explain one advantage of each.

Answer: Clay: easy to shape and carve. Cardboard: lightweight and inexpensive. Wire: flexible and useful for creating frameworks.

Question 3: Explain what is meant by 'texture' in 3D design and give an example of how texture can be added to a sculpture.

Answer: Texture refers to the surface quality or feel of a material, which can be smooth, rough, bumpy, etc. Texture can be added by carving patterns into clay or attaching different materials like fabric or sand.

Question 4: Sketch a simple 3D geometric shape, such as a cube or cylinder, and label its main features in the space provided.

Answer: A correct sketch would show a three-dimensional shape with visible edges, a clear base, and top face, with labels indicating the 'front face,' 'top,' and 'edges.'

Question 5: Describe the process of constructing a basic 3D form using papier-mâché.

Answer: Start by creating a wire or cardboard armature, then apply layers of papier-mâché strips coated in glue or paste over the frame. Allow each layer to dry before adding the next until the form is solid. Finally, you can paint or decorate the surface.

Question 6: Identify and explain two different ways to add stability to a free-standing sculpture.

Answer: One way is to widen the base to lower the center of gravity. Another is to use internal supports or frames to reinforce the structure and prevent it from toppling.

Question 7: Draw a design for an ergonomic handle that could fit comfortably in a hand. Include labels showing key features.

Answer: A good sketch would show a handle with a curved shape that fits the palm, with finger grooves or textured surface for grip. Labels might include 'curved shape,' 'finger grooves,' and ' textured surface.'

Question 8: Explain the importance of balance in 3D sculpture and how an artist can achieve it.

Answer: Balance is important to ensure the sculpture does not topple over. An artist can achieve balance by carefully distributing weight, positioning heavier parts at the bottom, and considering the overall shape.

Question 9: Sketch a concept for a small decorative 3D object, such as a jewelry box or paperweight, in the space provided.

Answer: The sketch should show a simple, recognizable shape with details like a lid, surface texture, or decorative elements, and be proportioned to fit on a small object like a paperweight.

Question 10: Describe how light and shadow can be used to enhance a 3D sculpture's appearance.

Answer: Light and shadow can highlight the form, surface textures, and contours of a sculpture. Shadows create depth, while highlights emphasize protruding or raised areas.
