In this lesson, students explore cross-sections of 3D objects. The lesson comes in the middle of the semester–long course in which students learn 3D computer imaging and work with actual 3D materials .
Age Group: 9th -12th grade
Goals:
1. To be able to visualize the shapes of cross-sections of a 3D object.
2. To imaginatively arrange and re-arrange 2D shapes to create new 3D forms.
3. To get inspiration from the interconnections between natural and constructed forms.
4. To learn how to use a 3D imaging program.
Process:
Part 1: Using 3D materials: (e.g., clay, plasticene, etc.)
1. Create a simple 3D object.
2. Think about different ways you could slice the object (horizontally, vertically, diagonally). What would the different slices look like? (What would the shapes be?)
3. Choose one way to slice the object. Look at the different cross-section shapes and draw them on paper or on the computer.
4. Put the cross-sections back together again in a new configuration. (Stack them in different orders, arrange them on the diagonal, stagger them, etc. to invent new 3D shapes.
Part 2: Using a 3D computer program (Cinema 4D):
1. Construct an object that makes a connection between an object from nature and a constructed object (e.g., a shell and a candlestick holder).
2. Experiment with re-arranging the order or placement of the cross-sections.
Standards:
1. Students demonstrate their powers of observation, abstraction, and invention and expression by using a variety off media and materials and techniques.
2. Students apply their knowledge of the arts to the study of science and technology/engineering. (Interdisciplinary connections)
Assessment Criteria:
1. Digital photo of 3D object before and after slicing
2. Drawings of cross-sections (slices of object)
3. Final 3D computer image
4. Presentation of images of entire process to class
